Minpaku Neighbor Complaints in Japan: Your Legal Duties and the 2026 Crackdown in Tokyo's Wards

Minpaku Neighbor Complaints in Japan: Your Legal Duties and the 2026 Crackdown in Tokyo's Wards

Last updated: October 28, 2026

Handling neighbor complaints at a Japanese minpaku is not a courtesy — it is a legal duty under the Housing Accommodation Business Act. You are expected to respond at any hour, including late at night, in July 2026 the national government told municipalities they may now ban minpaku outright in designated areas, and Shibuya, Toshima and Bunkyo wards have since tightened their ordinances (Shinjuku has published a draft).

"A neighbor called me at 1am. Am I really required to pick up every time?"

"The guest made the noise — so why am I the one getting the angry call?"

"If the complaints keep coming, what's the worst that can happen? Could I lose the business?"

Hello from the Digital Marketing team at AirHost. If you run a minpaku (a Japanese short-term rental), you probably know this already: once you open, neighbor relations are the part that really wears you down. You sort out the license, you install the equipment — and then one noise complaint sours things with the building. It happens more often than you'd think.

And this area moved a lot in 2026. Drawing on the Japan Tourism Agency's official minpaku portal, the July 15, 2026 advisory notice and Tokyo ward ordinances, this guide walks you through exactly how far your legal duties go, what changed in 2026, and what to do about it starting tomorrow.

⚡️ The 3-minute version

• There are two separate duties: explaining rules to guests before they stay (Article 9), and responding to complaints from neighbors afterwards (Article 10).

• Complaint response is expected at all hours, including late night and early morning — and even while no guest is staying.

• The shorthand: Article 9 is the system that prevents the noise; Article 10 is the responsibility after it happens.

• On July 15, 2026, the government issued an advisory stating that municipalities may impose "zero-day regulation" — effectively banning minpaku in specific areas. The 2017 guideline had called this "not appropriate."

• The same notice said municipalities may require ICT-based management by ordinance — noise meters, entrance cameras, and data retention.

• In short, complaint handling has moved from a matter of manners to a condition of staying in business.

What is the minpaku complaint-response duty?
Under Article 10 of Japan's Housing Accommodation Business Act, a housing accommodation business operator must respond appropriately and promptly to complaints and inquiries from residents in the area surrounding the notified property. Together with the Article 9 duty to brief guests on noise and waste, it exists to protect the living environment of the surrounding neighborhood.

1. Neighbor trouble is regulated, not just frowned upon

Let's start with the context. Here's something many people don't realize: the Housing Accommodation Business Act exists in large part because of neighbor trouble.

The Japan Tourism Agency lists the drivers behind the law as inadequate safety and sanitation, neighbor trouble from noise and garbage disposal becoming a social problem, and diversifying accommodation needs (Japan Tourism Agency minpaku portal, "What is the Housing Accommodation Business Act?", in Japanese).

So neighbor management is not a side condition of the framework — it is one of its founding purposes. Which is why the obligations are written in explicitly, in two stages:

• Before the stay: brief the guest (Article 9)

• After the stay begins: respond to neighbors (Article 10)

Think of a school trip. Before the train leaves, the teacher tells the class, "Keep your voices down on the train" — that's Article 9. If someone still gets loud, the teacher apologizes to the other passengers and steps in — that's Article 10. In a minpaku, you are the teacher.

2. Article 9: what you must explain to guests

The Tourism Agency's portal sets out four categories you must cover (Japan Tourism Agency minpaku portal, "Operator duties (1)", in Japanese).

Notice how specific the official examples are. A simple "Please be quiet" doesn't cut it. The expectation reaches down to "close the windows late at night" and "no parties on the balcony."

Foreign guests must be briefed in a foreign language

This one is easy to miss: for guests who are foreign tourists, the explanation must be given in a foreign language.

And it goes beyond Article 9. The same portal lists these requirements for ensuring the comfort and convenience of foreign tourists:

• Providing guidance on how to use the property's equipment, in a foreign language

• Providing information on transportation options, in a foreign language

• Providing guidance on emergency contact points in the event of fire, earthquake or other disaster, in a foreign language

• Other measures necessary to ensure the comfort and convenience of foreign guests

The more overseas guests you host, the heavier this gets. The good news? As we'll see below, it's also one of the easiest parts of the job to automate.

3. Article 10: responding at any hour, even with no guest present

The statutory wording is short. The government's July 2026 notice quotes it directly:

"Complaints and inquiries from residents of the area surrounding the notified property must be responded to appropriately and promptly."
(MHLW / MLIT / Japan Tourism Agency, "Zero-day regulation etc. for notified properties under the Housing Accommodation Business Act (technical advice)," July 15, 2026, in Japanese)

The question is what "appropriately and promptly" means in practice. The portal sets a demanding bar:

• Response is required at all times, regardless of late night or early morning, by answering in person or by telephone

• Complaints and inquiries must be handled even while no guest is staying at the property

• Respond in good faith, and state a deadline for your reply

• If the situation does not improve, take necessary steps such as rushing to the site and requesting that the guest leave

• Where urgent action is needed, contact the appropriate authorities — police, fire department, medical institutions

Bottom line: "business hours only" and "only when a guest is checked in" don't meet this standard. Sending calls to voicemail and calling back the next morning falls short.

From a neighbor's point of view, your contact number is like the phone line of a shop that's supposed to be open 24 hours. If nobody picks up at night, the next call goes to the city office — or the police.

And yes, the portal even mentions going to the property in person. Honestly, that's the tough part. If you self-manage a property far from where you live, you need a concrete plan for how that gets covered.

4. Comparison: Article 9 vs. Article 10

The two duties look similar but differ in audience, timing and purpose.

Put simply: Article 9 is the system that prevents the noise; Article 10 is the responsibility after it happens. The better you do Article 9, the less Article 10 you have to absorb.

5. July 2026: the national position changed

Here is the part worth your attention. On July 15, 2026, the Ministry of Health, Labour and Welfare, the Ministry of Land, Infrastructure, Transport and Tourism, and the Japan Tourism Agency jointly issued technical advice to prefectures and designated cities (Japan Tourism Agency press release, in Japanese).

The notice cites a large increase in notified properties and resulting concerns in some areas about "the quiet residential environment of residential districts and the maintenance of the resident population."

It covers two things.

① Zero-day regulation (locational restriction)

Municipalities may prohibit new minpaku operations in designated areas. Picture a calendar where every day you could start a minpaku in that area is crossed out. The notice gives these examples:

• Where, near residential districts or educational facilities, frequent guest traffic risks damaging the quiet residential environment or the wholesome environment of schools — prohibiting new operations, or limiting operating days to weekends and days before public holidays

• Where, in residential districts, the maintenance of the resident population or local community would otherwise become difficult — prohibiting new operations

The turning point is this note in the accompanying material:

The guideline (December 2017) had stated that zero-day regulation was "not appropriate."

So a restriction previously treated as going too far is now permitted, within reasonable limits.

Existing properties can be caught too

The notice goes further. Where many minpaku already operate, the quiet living environment is already significantly harmed, a strong necessity is recognised, and no other appropriate measure exists:

restrictions may also be considered for existing notified properties, after providing a certain grace period — such as prohibiting operation or limiting operating days to weekends and days before public holidays.

"Already operating" is no longer a guarantee. There is also a succession trap: in an area where new operations are prohibited, if the operator (notifier) changes, a fresh notification under Article 3 is required — and therefore the business cannot continue at that property. Worth knowing if you plan to sell or transfer.

② ICT-based management

The notice states that responding to complaints properly requires being able to identify their causes quickly and accurately, and that municipalities may consider requiring by ordinance:

installing noise meters and cameras at entrances, conducting monitoring, and retaining the data for a set period (such as the past one year).

It also states explicitly that even where no complaint has been made, if noise is occurring the operator must act on their own initiative. Waiting for a complaint is not the standard.

③ Other restrictions municipalities may set

The notice adds that ordinances may also set restrictions such as check-in/check-out time limits and caps on occupancy, according to local circumstances.

This is not a nationwide ban taking effect immediately. It is technical advice under Article 245-4(1) of the Local Autonomy Act, intended to guide municipalities drafting ordinances. What actually applies to you depends on your municipality's ordinance. The notice states its content will be reflected in the official guideline in due course.

④ Tokyo wards are already tightening their ordinances (as of October 2026)

Municipalities with many minpaku have started revising their ordinances. Key examples (effective dates and scope differ by ward):

As the table shows, the change is no longer only about new openings — some wards are cutting the operating days of existing properties. If you plan to buy, lease or take over a property in Tokyo, check the ward's latest rules before you commit.

6. What to do starting tomorrow

Translating the law into practice:

• Write house rules with concrete examples — not "be quiet" but "no balcony use after 10pm." The official examples can be used almost verbatim.

• Send them twice: at booking confirmation and the day before check-in. Few people read rules after arriving.

• Prepare foreign-language versions. This is an obligation, not a nicety.

• Match waste rules to the municipality. Separation rules are not national. Copy your local ones.

• Decide who answers at 2am. Forwarding number, named person, escalation steps — written down. Ambiguity here fails at exactly the wrong moment.

• Introduce yourself to neighbors and leave a contact number. It keeps complaints from going straight to the city or the police. Displaying the official sign is also a duty.

• Log every complaint — date, content, action taken, reply deadline. Where ICT management becomes an ordinance requirement, records become evidence of adequate management.

• Re-check your municipal ordinance periodically. Since the 2026 notice, several Tokyo wards have already changed their rules (see section 5).

On signage: per the portal, the sign must be displayed at each notified property in a location visible to the public, continuously while the business operates, positioned roughly 1.2–1.8 metres above ground, and made durable against wind and rain (for example laminated). In apartment buildings, a simple sign should also be displayed at the shared entrance, mailboxes or similar visible locations.

7. For operators: the prevention side can be systematised

By now you might be thinking, "Responding around the clock, on my own? No way." We completely understand.

Straight answer: ICT management using noise meters and cameras requires dedicated hardware. That is not an AirHost feature. Speak to a specialist vendor for that.

But most neighbor trouble is reduced at the entrance — and the entrance, meaning the Article 9 briefing and your communication channel with guests, is exactly what a system handles well.

AirHost is a cloud platform combining a property management system and a channel manager. The parts relevant here:

• Automated messages — send guidance automatically at set points such as after booking or before check-in, so house rules go out every time without manual effort

• AI Assistant — reservation-aware AI that detects the guest's language and replies in multiple languages, 24/7. It references reservation data and stay status (dates, guests, room type, rate plan, payment status), maintains conversation history, works across OTA messaging channels, and includes issue detection with staff notification. It is natively integrated into AirHost HMS / AirHost ONE (AirHost AI Assistant)

• Messaging (chat / email / SMS / social) and phone — guest communication consolidated in one place

• Smart lock integration and on-site arrival authentication (GPS / Wi-Fi) — clearer visibility of who entered and when

• Channel manager — bookings across Airbnb, Booking.com, Expedia, Rakuten Travel and other platforms in one view

This matters directly for compliance. Briefing foreign guests in a foreign language is an obligation, not a nicety (see section 2) — and doing it manually breaks down as soon as you have guests arriving in several languages. If you operate in Japan without fluent Japanese-language staff on call at 2am, the multilingual 24/7 layer is the part that makes the Article 9 duty repeatable.

Not just neighbor trouble: the small daily tasks, all in AirHost

Think about your living room. A TV remote, an air-conditioner remote, a light remote… with that many, you keep grabbing the wrong one. One remote that runs everything would make life a lot easier.

AirHost is that "one remote" for running your property. On top of the guest briefings and guest messaging above, the everyday tasks sit on the same screen:

• Bookings: bookings from Airbnb, Booking.com and other OTAs in one place (Channel Manager)

• Cleaning: cleaning schedules on a calendar, with cleaners notified automatically (PMS)

• Room assignment: rooms assigned and optimized automatically (PMS)

• Payments: authorizations, payments and cancellation fees charged automatically according to each booking's cancellation policy (Auto Payment Collection)

• Guest registry: track how many guests completed the registry before arrival (PMS)

• Revenue: revenue, occupancy, ADR and RevPAR in reports (PMS)

In short: put the routine work into AirHost, and spend your own time on your neighbors. "Admin for the system, neighbors for people" — that's the most sustainable way to run it, in our view.

Frequently asked questions

Q. Do I really have to answer complaints in the middle of the night?

Yes. The Tourism Agency's portal states that response is required at all times, regardless of late night or early morning, in person or by telephone — and that complaints must be handled even while no guest is staying (Japan Tourism Agency, "Operator duties (1)", in Japanese). Voicemail with a next-morning callback does not meet this standard.

Q. If complaints keep coming, could I lose my business?

Complaints alone do not automatically trigger a shutdown. But under the July 15, 2026 technical advice, in areas where many minpaku already operate and the living environment is already significantly harmed, municipalities may by ordinance prohibit new operations and — after a grace period — impose restrictions on existing notified properties as well (technical advice, full text PDF, in Japanese). Deterioration of the area as a whole can bring regulation.

Q. What is "zero-day regulation"?

A locational restriction that effectively reduces permitted operating days to zero in a designated area, prohibiting new minpaku there. The December 2017 guideline had called it "not appropriate"; the July 2026 technical advice recognised it as possible within reasonable and necessary limits (Japan Tourism Agency press release, in Japanese).

Q. Is there a fixed list of what I must tell guests?

Yes — the portal sets out four categories: noise prevention, waste disposal, fire prevention, and other matters (such as not using sexual services in the property). Each comes with official examples, down to closing windows at night and not holding parties on balconies (Japan Tourism Agency, "Operator duties (1)", in Japanese).

Q. Must foreign guests be briefed in their own language?

Yes. Guests who are foreign tourists must receive the explanation in a foreign language. Guidance on equipment use, transportation, and emergency contact points is also required in a foreign language (Japan Tourism Agency, "Operator duties (1)", in Japanese).

Q. Have any Tokyo wards restricted minpaku further?

Yes. As of October 2026, Shibuya (for notifications filed on or after July 1, 2026), Toshima (from December 16, 2026: operation limited to 120 days a year across the ward, including existing properties) and Bunkyo (from January 7, 2027: weekday operation restricted across the ward) have revised their ordinances, and Shinjuku has published a draft for public comment. Sources: the official pages of Shibuya, Toshima, Bunkyo and Shinjuku (in Japanese).

Q. Do I need to install noise meters and cameras now?

As of October 2026 this is not a nationwide requirement. The July 2026 technical advice indicates municipalities may require ICT management by ordinance — noise meters, entrance cameras, and retention of data for a period such as the past year (technical advice, full text PDF, in Japanese). Check your own municipality's ordinance.

Summary

Neighbor management at a Japanese minpaku carries two legal duties:

• Article 9 — brief guests before the stay (noise, waste, fire, other; in a foreign language for foreign guests)

• Article 10 — respond to neighbors' complaints at all hours and even when no guest is staying

On July 15, 2026 the national position shifted, and several Tokyo wards have since revised their ordinances. Zero-day regulation, previously called "not appropriate" in the 2017 guideline, is now recognised as possible — and existing properties may be restricted after a grace period. Municipalities may also mandate ICT-based management by ordinance.

Complaint handling has become a condition of staying in business rather than a matter of manners. The practical response has not changed, though: build the system that prevents the noise first. That is Article 9, and it is what keeps Article 10 manageable.

Actual restrictions vary by ordinance. Always confirm the current rules with your own municipality.
