Is Airbnb Legal in Japan? 2026 Minpaku Law, 180-Day Rule, Tokyo Wards, Fines & Complete Expat Guide
The definitive English-language guide for expats, non-residents, and foreign property investors renting on Airbnb in Japan. Covers the Minpaku Law (住宅宿泊事業法), the 180-day annual cap, Tokyo's ward-by-ward restrictions (Shinjuku weekends only, Shibuya school holidays only), Okinawa's beach STR opportunity, the three legal pathways, 80% condo HOA ban rate, fire safety inspections, non-resident tax at 20.42%, fines up to JPY 1,000,000, and how to build a tamper-proof compliance file.
June 15, 2018: Airbnb delisted 80% of its Japan listings overnight -- approximately 48,000 properties removed in a single day. Hosts who had been earning steady income for years woke up to cancelled bookings, stranded guests, and zero revenue. Airbnb created a $10 million emergency fund to cover guest rebookings. An estimated 80% of all reservations during the transition period were cancelled.
January 2026: Tokyo's first criminal prosecution under the Minpaku Law. A 34-year-old Chinese CEO of K-Carve Life in Shinjuku was referred to prosecutors for operating illegally on weekdays in Arakawa Ward (weekends only allowed). The company accommodated 590 foreign tourists over 3.5 years, earning JPY 22 million. They falsely reported only 8 days of operation when they actually operated 49 illegal days in a two-month period. Multiple noise complaints, illegal garbage dumping, groups of 7-8 guests at a time.
Now imagine this: Shinjuku Ward has issued 30-day business suspension orders to 12 operators and permanent discontinuation orders to 4 operators (banned for 3 years). Complaints surged from 70 cases (2021) to over 900 (2025). Your listing is legal -- but can you prove you only operated on permitted days?

British national arrested in Tokyo (2017) -- first foreigner prosecuted
A 28-year-old British male was arrested for operating an unlicensed minpaku from a 3-room wooden house in Tokyo, offering rooms at JPY 2,500-5,000/person/night. Received a summary criminal order (略式命令). One of the first arrests of a foreigner under the Hotel Business Act.
K-Carve Life, Shinjuku -- first criminal referral under Minpaku Law (Jan 2026)
Chinese CEO and one other person referred to prosecutors. Operated illegally on weekdays in Arakawa Ward (weekends only). 590 foreign tourists, JPY 22 million revenue over 3.5 years. Falsified operating day reports. Multiple noise complaints, groups of 7-8 guests, illegal garbage dumping. Ignored improvement orders. The CEO told investigators he believed it was acceptable because "other operators were doing the same."
Tokyo District Court -- condo owner ordered to pay JPY 970,000 (Aug 2018)
Owner purchased apartment in 2015, listed on Airbnb at JPY 13,000/night. Building association amended bylaws with 75%+ approval to ban STR. Owner claimed he stopped but guest reviews continued appearing. Court ordered owner to pay JPY 970,000 in legal fees to the association. At the time, only 0.3% of Japanese HOAs had approved short-term letting.
Osaka Minami -- JPY 32.67 million lawsuit (Aug 2017)
Condo management association filed suit seeking JPY 32.67 million in damages against Chinese and Japanese property owners operating minpaku via Airbnb and Chinese platform Zizaike. Separate Osaka District Court ruling (Jan 2017) awarded JPY 500,000 in attorney fees, stating operations "may constitute circumvention of the Hotel Business Act."
Shinjuku Ward -- 12 operators suspended, 4 permanently banned (Sep 2025)
Complaints surged from 70 (2021) to over 900 (2025). Ward issued 30-day suspension orders to 12 operators (22 facilities) and permanent discontinuation orders to 4 operators (11 facilities) -- banned from operating for 3 years. 37 operators violated reporting obligations.
Osaka "Illegal Minpaku Eradication Team" -- 4,200 operations shut down (2018-2020)
68-person team including former police officers, established April 2018 ahead of G20 Osaka Summit. In the first four months: investigated over 2,000 illegal operations, ordered over 1,800 shut down (over 80% of suspected cases). Coordinated with Osaka Prefectural Police and health inspectors.
Ota Ward, Tokyo -- sewage overflow from neighbor's Airbnb
A woman experienced repeated problems when her neighbor's house became a vacation rental hosting up to 10 guests at a time. The sewage system overflowed into her adjacent property. She reported: "Things like finely shredded toilet paper came out, and the smell was awful." Repeated noise and abandoned trash issues.
Minpaku Law caps hosting at 180 days/year. Tokyo wards go further: Shinjuku weekends only, Shibuya school holidays only, Toshima 120 days from April 2026. 80% of condo HOAs ban minpaku. Fines: up to JPY 1,000,000 + 6 months prison. Non-residents: 20.42% withholding tax, licensed management company mandatory. The bottom line: 2018 purge deleted 80% of listings overnight. 2025-2026 enforcement is intensifying -- first criminal prosecution in January 2026, Shinjuku suspended 12 operators, Osaka shut down 1,800+. You need timestamped proof of your operating days, registration, and compliance.

I. Is Airbnb Legal in Japan? The Minpaku Law (住宅宿泊事業法) Explained
The Private Lodging Business Act (住宅宿泊事業法, commonly called the "Minpaku Law") was enacted on June 15, 2018, after years of debate over Japan's rapidly growing -- and largely unregulated -- home-sharing market. Before the law, an estimated 50,000+ unregistered Airbnb listings operated in a legal gray zone across Japan.
The law created a legal framework for renting private homes to tourists, but with strict conditions:
- 180-day annual cap: No property may be rented as a minpaku for more than 180 days in any calendar year. Many municipalities impose even tighter limits.
- Mandatory registration (届出): Every host must file a notification with the prefectural governor and receive a registration number before listing on any platform.
- Platform compliance: Airbnb, Booking.com, and other platforms must verify that every listing displays a valid registration number. Listings without one are removed.
- Guest records: Hosts must maintain a guest register (宿泊者名簿), including passport copies for all non-Japanese guests, and report guest information to local police.
- Management company requirement: If the host does not live in or near the property ("owner-absent" type), they must appoint a licensed residential lodging management company (住宅宿泊管理業者).
- Signage: A sign must be posted near the property entrance indicating it is a registered minpaku, with the registration number displayed.
- Biannual reporting: Hosts must submit activity reports to authorities every two months.
Key numbers
Japan welcomed 42.7 million visitors in 2025 (target: 60 million by 2030). Demand for short-term accommodation is growing -- but so is enforcement. The 2018 law transformed Japan from unregulated home-sharing into one of the most tightly regulated STR markets in the world.
Registration makes you legal. It does NOT make you safe.
The minpaku registration solves the legal framework problem. But it does not solve the proof problem. Because:
- -- Your ward can accuse you of operating on prohibited days -- K-Carve Life was registered but operated weekdays illegally and got criminally prosecuted
- -- Your HOA can change bylaws at the next general assembly -- and claim they "always" prohibited minpaku (80% ban rate)
- -- Your bimonthly reporting can be disputed -- the centralized system goes live April 2026 for real-time matching
- -- Your neighbors file 900+ complaints in Shinjuku alone -- one sustained complaint triggers a full investigation of your operation
- -- The NTA can audit your income -- 20.42% withholding on gross, with 15-40% surcharges for underreporting
Registration makes your minpaku legal. Timestamped evidence makes it provable. When the ward office, your HOA, or the NTA asks for proof, a screenshot you took today does not prove what your listing or bylaws said six months ago. A blockchain-locked capture does.
II. Minpaku vs Ryokan vs Special Zone: Three Legal Pathways
Japan offers three distinct legal frameworks for operating a short-term rental. Each has different requirements, limits, and costs. Choosing the right one depends on your property, location, and business goals.
| Feature | Minpaku (New Law) | Simple Lodging (旅館業法) | Special Zone Minpaku |
|---|---|---|---|
| Day limit | 180 days/year (less in some wards) | None (365 days) | None (365 days) |
| Minimum stay | 1 night | 1 night | 2 nights / 3 days minimum |
| Authorization type | Notification (届出) | License (許可) | Certification (認定) |
| Difficulty | Easiest | Hardest (building codes) | Medium (limited zones) |
| Fire safety | Basic (detectors, extinguisher) | Full hotel-grade | Enhanced (closer to hotel) |
| Building type | Residential only | Commercial zones OK | Designated zones only |
| Available zones | Nationwide | Nationwide | Ota Ward, parts of Osaka, etc. |
| Setup cost | JPY 100K-500K | JPY 500K-3M+ | JPY 200K-1M |
| New applications (2026) | Open | Open | Frozen in some areas |
For most expat investors: Pathway 1 (minpaku) is the easiest entry point. Registration is a notification -- the government cannot refuse if you meet requirements. The trade-off is the 180-day cap. Pathway 2 (Simple Lodging) offers year-round hosting but requires hotel-grade building codes and JPY 3M+ in renovations. Pathway 3 (Special Zone) allowed year-round operation in Ota Ward and Osaka, but new applications are frozen in both areas since late 2025.
III. Airbnb Tokyo Rules: Ward-by-Ward Restrictions
While the national Minpaku Law sets the 180-day ceiling, individual Tokyo wards impose far tighter restrictions. These local ordinances (条例) can limit when and where you can host. Understanding your specific ward's rules is essential before purchasing any property for STR use.
| Ward | Restriction | Effective days | Notes |
|---|---|---|---|
| Shinjuku | Weekends and national holidays only (residential areas) | ~150 days/year | One of Tokyo's strictest wards for residential zones |
| Shibuya | School holidays only (residential areas) | ~60-80 days/year | Designed to prevent children encountering strangers on school routes |
| Minato | Weekdays restricted in residential zones | ~150 days/year | Commercial areas less restricted |
| Toshima | Reduced to 120 days/year + 70% of ward banned | 120 days/year | Effective April 1, 2026; existing facilities must comply by Dec 16, 2026 |
| Sumida | Friday noon to Sunday noon only (new facilities; unless superintendent on site) | ~100 days/year | Effective April 2026. Existing facilities exempt. |
| Ota | Special Zone -- year-round possible | 365 days (min 2 nights) | New applications frozen since Oct 2025 |
| Chiyoda | No additional restrictions beyond national law | 180 days/year | Relatively permissive |
| Taito (Asakusa) | No additional restrictions beyond national law | 180 days/year | Tourist-friendly zone near Senso-ji |
| Other major cities | |||
| Kyoto (residential zones) | January 15 to March 16 only | ~60 days/year | Strictest in Japan. New accommodation tax from March 2026: JPY 200-10,000/night (tiered by room rate) |
| Osaka (Special Zone) | New applications frozen (Oct 2025) | 365 days (min 2 nights) | Existing licenses valid. Standard minpaku (180-day) still accepted |
The practical impact: In Shibuya's residential zones, your 180-day national cap effectively becomes ~60-80 days during school holidays (spring break, summer, winter break, Golden Week). In Shinjuku residential areas, weekday hosting is banned, cutting your available days to roughly 150. If your target market is business travelers who book weeknights, Shinjuku and Shibuya are poor choices.
Commercial vs. residential zones: Many ward restrictions apply only to residential zones (住居専用地域). Properties in commercial or mixed-use zones may face fewer restrictions. Check the zoning designation (用途地域) of your specific property -- this information is available at the ward office or online via the Tokyo Metropolitan Government's zoning maps.
Evidence tip: Ward-level ordinances change frequently. Capture the current ordinance page for your ward with ProofSnap, creating blockchain-timestamped proof of what rules were in effect when you registered. If rules tighten later, your timestamped capture proves you were compliant under the rules that existed at the time.
IV. Okinawa: The Beach STR Opportunity
While Tokyo's dense urban wards are tightening regulations, Okinawa presents a different picture. Japan's subtropical beach resort prefecture is one of the fastest-growing STR markets in the country, with 693 new listings added in 2025 alone.
Okinawa STR market data (2025)
Why Okinawa works for expat investors
- More permissive local regulations: Unlike Tokyo's wards, Okinawa's municipalities generally do not impose additional restrictions beyond the national 180-day cap. Some areas allow Special Zone minpaku for year-round operation.
- Strong demand from US military community: Okinawa hosts multiple US military bases (Kadena, Camp Foster, Camp Hansen). Military personnel on temporary duty, families in transition, and visiting relatives create consistent demand for furnished short-term rentals -- a market that doesn't depend on tourism seasons.
- Resort vacation market: Okinawa's beaches, diving, and subtropical climate attract domestic and international tourists year-round, with peaks during Golden Week (late April-May), summer (July-August), and New Year.
- Lower property prices: Compared to Tokyo, Okinawa property prices are significantly lower, improving ROI. A beachfront apartment or small house suitable for STR can cost JPY 15-30 million ($100K-$200K) vs. JPY 50-100M+ in central Tokyo.
- Detached houses available: Unlike Tokyo where condominiums dominate (and 80% ban minpaku), Okinawa offers more detached houses and small villas that avoid the condo HOA problem entirely.
Key risks: Typhoon season (June-October) causes cancellations. Distance management requires a local management company. Outside Naha, guests need parking (limited public transport).
V. How to Register Minpaku as a Foreigner (Step by Step)
Registering a minpaku as a foreigner in Japan is a bureaucratic process that requires patience. Here is the step-by-step process:
Verify your eligibility
You must either hold a valid Japanese residence status (visa) or appoint a domestic representative. Non-resident foreigners can own and operate minpaku, but all communications with authorities must go through a Japan-based representative. Many judicial scriveners (司法書士) offer this service.
Check building eligibility
Confirm that the building's management bylaws (管理規約) do not prohibit minpaku. For condos, obtain written confirmation from the management association. Check the zoning designation (用途地域) and any ward-specific ordinances.
Consult the fire department
Visit the local fire department (消防署) with your floor plans. They will specify required fire safety equipment. After installation, schedule a fire inspection. Upon passing, you receive the Fire Law Conformity Certificate (消防法令適合通知書).
Contract a management company (if owner-absent)
If you do not live in or adjacent to the property, you must contract a licensed residential lodging management company (住宅宿泊管理業者). They handle guest check-in, safety monitoring, complaints, and cleaning. Fees typically range from 15-25% of revenue.
File the notification (届出)
Submit the notification to the prefectural governor (or designated city) through the Minpaku System online portal or at the local government office. Required documents: floor plans showing room sizes and fire equipment, fire safety certificate, proof of ownership or lease, management company contract, and condominium management association confirmation (if applicable).
Receive your registration number and begin hosting
After processing (typically 2-4 weeks), you receive your registration number (届出番号). Display this on all platform listings and on signage at the property entrance. You can now list on Airbnb, Booking.com, and other platforms.
Evidence tip: Capture your registration confirmation page, your listing showing the registration number (届出番号), and your management company contract with ProofSnap. This creates blockchain-timestamped proof of your compliance date. If authorities question your registration status, you have immutable evidence showing when you registered and that your listing displayed the correct number.
VI. Can Your Condo Ban Airbnb? The 80% HOA Rejection Rate
This is the single biggest pitfall for foreign investors in Japanese STR. A survey by the Condominium Management Companies Association (CMCA) found that 80% of homeowners' associations (管理組合) ban minpaku operations. Only 0.3% of surveyed associations explicitly allow it.
Why the bans? Japanese condo culture prioritizes quiet, orderly communal living. The concerns are practical:
- Noise from tourists in late hours
- Improper waste sorting (Japan has strict recycling rules)
- Strangers in common areas -- security concerns, especially in buildings with children
- Elevator and facility overuse
- Language barriers preventing guest compliance with building rules
How to check before buying
- Request the management bylaws (管理規約) from the seller or real estate agent before purchasing
- Look for explicit language about 住宅宿泊事業 (private lodging business) or 民泊 (minpaku)
- Check the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) model bylaws -- if your condo uses the standard template, it likely includes a minpaku prohibition clause
- Ask the management company (管理会社) directly
- Review recent general assembly (総会) minutes for any minpaku-related discussions or votes
Evidence tip: If your building's 管理規約 permits minpaku, capture it with ProofSnap immediately. HOA rules can change at the next general assembly meeting. A blockchain-timestamped capture proves what the bylaws stated when you began operations -- critical if the rules change after you've already invested.
The safe alternative: Detached houses (一軒家) and akiya (vacant/abandoned houses, of which Japan has ~9 million) avoid the condo HOA problem entirely. Many akiya can be purchased for JPY 1-10 million ($6,500-$65,000) and renovated for STR use, particularly in tourist areas outside major cities.
VII. Fire Safety Requirements
Fire safety compliance is a non-negotiable prerequisite for minpaku registration. The requirements vary based on whether the host is present ("host-present") or absent ("host-absent"):
Required equipment (all minpaku)
- Smoke detectors (火災警報器) in every guest room and hallway
- At least one fire extinguisher (消火器)
- Clear escape route markings posted in guest rooms (in English and Japanese for foreign guests)
- Emergency contact information displayed prominently
Owner-absent properties require more
Emergency exit signs (誘導灯) and emergency lighting (非常照明) -- same as commercial lodging. Properties under 50 sqm guest area qualify as "general housing" with simpler requirements.
Inspection process
Submit floor plans to local fire department → install equipment → schedule inspection → receive Fire Law Conformity Certificate (消防法令適合通知書). This certificate is required for minpaku registration.
Evidence tip: Capture your Fire Law Conformity Certificate (消防法令適合通知書) with ProofSnap. Fire safety certificates can be lost, and fire departments may not retain records indefinitely. A blockchain-timestamped capture proves your property passed inspection on a specific date.
VIII. How Much Tax Do Foreigners Pay on Airbnb Income in Japan?
Japan's tax system for STR income is complex, especially for non-residents. Three tax categories apply:
1. Income tax (所得税)
- Residents (tax residents of Japan): Progressive rates from 5% to 45%, plus a 2.1% surtax on the income tax amount (for reconstruction after the 2011 earthquake)
- Non-residents: Flat rate of 20.42% on Japan-sourced rental income (20% tax + 2.1% reconstruction surtax)
- Filing deadline: March 15 of the following year
- Tax representative: Non-residents must appoint a tax agent (納税管理人) in Japan to handle filings and communications with the National Tax Agency (NTA)
2. Consumption tax / JCT (消費税)
- Japan's consumption tax rate is 10%
- If your annual STR revenue exceeds JPY 10 million (~$65,000), you become a "taxable enterprise" and must charge, collect, and remit consumption tax
- Below JPY 10M: you are a tax-exempt enterprise (免税事業者) for JCT purposes
- Note: The JPY 10M threshold is based on base period revenue (two years prior), so your first two years may be exempt regardless
3. Accommodation tax (宿泊税)
This is a local tax that varies by municipality. Not all cities impose it, and minpaku properties may be exempt in some jurisdictions. Key rates:
| City | Rate per guest per night | Notes |
|---|---|---|
| Tokyo | JPY 100-200 ($0.65-$1.30) | Tiered by room rate; being expanded in 2026 |
| Kyoto | JPY 200-1,000 ($1.30-$6.50) | Highest in Japan; applies to all accommodation types |
| Osaka | JPY 100-300 ($0.65-$2.00) | Tiered by room rate |
| Fukuoka | JPY 150-450 ($1.00-$3.00) | Introduced 2020 |
Platform reporting: Airbnb and other platforms report host income data to the Japanese National Tax Agency. Non-compliance with tax filing obligations can result in penalties, back-taxes with interest, and -- in severe cases -- revocation of your minpaku registration.
Tax tip: ProofSnap is a deductible business expense for STR hosts in Japan under 必要経費 (necessary expenses). At $16.99/month ($203.88/year), it reduces your taxable income while protecting your compliance record. Other deductible expenses include management company fees, cleaning, furnishings, insurance, and platform commissions.
IX. What Happens If You Get Caught? Fines & Enforcement
Japan takes illegal minpaku seriously. Enforcement has intensified significantly since 2018, and 2025-2026 has seen a further crackdown driven by noise complaints and tourism pressure.
| Violation | Maximum penalty |
|---|---|
| Operating without minpaku registration | JPY 1,000,000 (~$6,500 USD) |
| Operating as unlicensed hotel (旅館業法 violation) | JPY 1,000,000 + up to 6 months imprisonment |
| Exceeding 180-day limit | Business suspension order + registration revocation |
| Failure to keep guest records | JPY 300,000 (~$2,000 USD) |
| Failure to report foreign guests to police | JPY 300,000 (~$2,000 USD) |
| Violating ward-specific operating hours | Business improvement order + potential registration revocation |
How you get caught
- Neighbor complaints: In Japan's tight-knit communities, noise and nuisance complaints trigger investigations within 2-4 weeks. A single sustained complaint can force you to cease operations.
- Platform data sharing: Airbnb and Booking.com share data with authorities. From April 2026, the centralized system matches listings against registrations in real-time.
- Ward-level inspections: Shinjuku and Osaka actively scan platforms and conduct on-site inspections (see real cases above).
Shinjuku suspended 12 operators. Osaka shut down 1,800+. Are you next?
Authorities use listing screenshots, day-count records, and guest reviews as evidence. If you are compliant, prove it -- before an investigation starts. 7-day free trial.
X. The 2018 Airbnb Purge: Lessons for 2026
The June 2018 purge (detailed in the real cases section above) taught four lessons that matter even more in 2026:
- Platforms will comply instantly: Airbnb delisted 80% of listings in one day rather than risk its own legal position. Never assume a grace period.
- Registration backlogs are real: In 2018, hosts who applied late missed the deadline because government offices were overwhelmed. Register early.
- No grandfather clause: There was no transition period. When the law took effect, compliance was immediate.
- Documentation is your re-entry ticket: Hosts who could demonstrate prior compliance (guest records, tax filings) re-entered the market faster. Hosts with no records struggled.
In 2025-2026, enforcement is intensifying again: Toshima Ward cut its limit to 120 days (April 2026), Sumida Ward restricted to weekends only, and the new centralized management system (一元管理システム) goes live April 2026 for real-time platform-to-registry matching. Compliance is not optional, and documentation is your insurance policy.
XI. Osaka Special Zone Freeze
In October 2025, Osaka City announced it would suspend acceptance of new applications for Special Zone minpaku. This means the pathway to year-round operation (without the 180-day cap) is temporarily blocked in Osaka.
Triggered by market saturation: 9,599 active listings, complaints about overtourism in Namba, Shinsaibashi, Tennoji. Key facts: existing licenses remain valid (freeze = new applications only). Standard minpaku (180-day) still accepted. Simple Lodging licenses still available. No timeline for lifting the freeze. Ota Ward (Tokyo) also frozen. If you already hold a Special Zone license: it is now a scarce asset that may increase property value.
XII. Managing Your STR from Abroad
For expats living outside Japan -- or even in a different Japanese city from their property -- the Minpaku Law mandates appointing a licensed residential lodging management company (住宅宿泊管理業者). This is not optional: it is a legal requirement for all "owner-absent" properties.
The management company handles check-in, guest ID, police reporting, 24-hour emergency contact, cleaning, day-count tracking, and biannual reports. Typical costs: 15-25% of revenue + JPY 5,000-15,000/turnover cleaning + JPY 50,000-200,000 one-time setup.
Additional requirements: Non-residents must appoint a tax representative (納税管理人) and open a Japanese bank account for income and tax payments.
Evidence tip: Your management company can run the ProofSnap capture protocol on your behalf -- taking monthly screenshots of your listing, guest reviews, and compliance dashboard. You don't need to be in Japan to build your compliance file. One capture per month, 10 seconds, blockchain-timestamped.

XIII. 5 Real Situations Where Timestamped Proof Saves You
Japan's enforcement is intensifying -- Shinjuku complaints surged from 70 to 900+ in four years, and Osaka's Eradication Team shut down 4,200 operations. Here are five situations where timestamped proof is the difference between keeping your license and losing it.
-
1. Ward office accuses you of operating on prohibited days
Like K-Carve Life in Arakawa Ward: you operate weekends only (as allowed), but the ward claims you had guests on weekdays. They check your listing today -- but what did your calendar show 3 months ago? K-Carve falsified reports and got criminally prosecuted.
With ProofSnap: Monthly captures of your Airbnb calendar and availability settings, each with a blockchain timestamp, prove you only had bookings on permitted days. The ward verifies each capture independently. Case closed.
-
2. Your condo HOA amends bylaws to ban minpaku
Like the Tokyo District Court case: you bought your unit when bylaws allowed STR. The HOA votes to ban it and claims the bylaws "always prohibited" short-term rentals. You have no proof of the original rules. The court awarded JPY 970,000 against the owner.
With ProofSnap: Your 2024 blockchain-timestamped capture of the management agreement proves what was permitted when you purchased. The ban applies prospectively, not retroactively.
-
3. Bimonthly reporting: proving your day count to the ward
Japan requires bimonthly activity reports (定期報告) to the prefectural government -- your cumulative day count, guest numbers, and operating details every two months. From April 2026, the new centralized management system (一元管理システム) matches platform listings in real-time against registration data. If the system flags a discrepancy, you need to prove what your dashboard showed when you filed. Your management company's spreadsheet is disputable.
With ProofSnap: Capture your Airbnb dashboard showing cumulative day count before each bimonthly submission. If the ward disputes your numbers six months later, you have blockchain proof of what the dashboard showed on the exact day you filed. No other tool provides this.
-
4. Neighbor files a complaint and ward investigates
In Ota Ward, a neighbor's sewage overflowed from an Airbnb hosting 10 guests. In Shinjuku, 900+ complaints in one year. When a neighbor complains, the ward investigates your entire operation -- registration, day count, guest records, listing accuracy.
With ProofSnap: You show your listing (correct registration number displayed), your calendar (within day limits), and your house rules (quiet hours, max guests). All timestamped. The investigator sees documented compliance and moves on.
-
5. Tax audit -- NTA questions your income vs. reported earnings
Non-residents face 20.42% withholding. Late filing penalties: 15-30% surcharge. If the NTA finds undeclared income from Airbnb, you face back taxes plus penalties of up to 40% on underreported amounts.
With ProofSnap: Monthly captures of your Airbnb payout history, booking confirmations, and management company invoices create a complete financial trail. Your tax representative uses it to reconcile every yen.
Cost perspective: ProofSnap costs $16.99/month. A Japanese property lawyer (不動産弁護士) costs JPY 30,000-50,000/hour. A minpaku fine is JPY 1,000,000. The Osaka Minami HOA lawsuit sought JPY 32.67 million. Monthly captures take five minutes and cost less than a single bento box.
XIV. 15-Point Compliance Checklist
XV. Frequently Asked Questions
Can foreigners legally run an Airbnb in Japan in 2026?
Yes. There is no nationality requirement for minpaku registration. However, non-resident foreigners must appoint a domestic representative for government communications and a tax representative (納税管理人) for tax filings. If you don't live in the property, a licensed management company is mandatory. The biggest practical barrier is the 80% condo HOA ban rate -- not nationality.
What happens if I exceed the 180-day limit?
You will receive a business improvement order from the prefectural governor, which can escalate to a business suspension order and ultimately registration revocation. If you continue operating after revocation, you face fines up to JPY 1,000,000 and potential criminal prosecution under the Hotel Business Act. Platforms also track day counts and may automatically suspend your listing.
Is Okinawa a good market for STR investment as a foreigner?
Okinawa is one of Japan's strongest STR markets for foreign investors. Median occupancy is 70%, average daily rate is JPY 21,327 ($136), and average annual revenue is approximately JPY 5 million ($32,000). Lower property prices than Tokyo, more detached houses (avoiding the condo ban problem), steady demand from US military personnel, and less restrictive local regulations make it attractive. The main challenges are typhoon risk, distance management, and car dependency for guests.
How much does it cost to set up a minpaku in Japan?
For a standard minpaku registration: JPY 100,000-500,000 ($650-$3,250) including fire safety equipment installation, management company setup fee, signage, and administrative costs. For a Simple Lodging license under the Hotel Business Act: JPY 500,000-3,000,000+ ($3,250-$19,500+) due to stricter building and fire codes. The property itself is separate -- Tokyo condos start around JPY 30-50 million ($195K-$325K), while Okinawa detached houses can be found for JPY 15-30 million ($100K-$195K).
Can my condo HOA ban minpaku after I've already started?
Yes. The management association can amend the bylaws (管理規約) at a general assembly meeting with a 3/4 majority vote. If minpaku is banned after you've started operating, you must cease operations. This is why capturing your bylaws with ProofSnap before starting is critical -- it establishes what the rules were when you began, which may be relevant in any dispute over transition periods or damages.
Do I need to report foreign guests to the police?
Yes. Under the Minpaku Law, hosts must maintain a guest register (宿泊者名簿) that includes name, address, nationality, passport number, and dates of stay for all non-Japanese guests. This information must be submitted to the local police. Your management company typically handles this obligation, but you remain legally responsible.
What is the difference between Shinjuku and Ota Ward for Airbnb?
Shinjuku uses the standard minpaku framework with strict ward-level restrictions: hosting is limited to weekends and national holidays only in residential areas (~150 days/year max, often less). Ota Ward is a National Strategic Special Zone where year-round operation was possible with a special certification (no 180-day cap), but with a minimum 2-night/3-day stay requirement. However, Ota Ward has frozen new special zone applications as of late 2025. New operators in Ota can still register under the standard minpaku law (with the 180-day cap).
How does the 2018 Airbnb purge affect me as a new host in 2026?
The 2018 purge (when Airbnb delisted ~80% of Japan listings overnight) demonstrates that platforms will enforce compliance without warning. In 2026, the lesson is: never list without a valid registration number. Airbnb Japan actively verifies registration numbers and removes non-compliant listings. If new regulations are introduced, expect immediate enforcement -- there will be no grace period. Register early, maintain documentation, and keep timestamped evidence of your compliance.
