Staying in a Japanese home, and knowing it's legal
By Minpaku X editorsUpdated 3 min read4 sources
The short answer
A minpaku puts you in a home, with someone who knows the place. A legal one holds one of three permissions: a minpaku registration (住宅宿泊事業, up to 180 nights a year), an inn licence (旅館業) or a special-zone certificate (特区民泊). Ask for its number and look for the sign at the door.
Three ways to be legal
Anyone in Japan who takes money to put up travellers needs a permission from the government. For homes and small inns there are three, and each sets its own rules for how many nights the place may open.
| Permission | Law | Nights a year | The number |
|---|---|---|---|
| Minpaku registration (住宅宿泊事業) | 住宅宿泊事業法 (2018) | Up to 180, from noon on 1 April | "M" and nine digits (to verify) |
| Ryokan, hotel or simple lodging (旅館業) | 旅館業法 | Every night | Set by the local health centre |
| Special-zone minpaku (特区民泊) | 国家戦略特別区域法 | Every night; stays of two nights or more (to verify) | Set by the city |
The 180-night rule
A home registered as a minpaku may host paying travellers on up to 180 nights a year. The year runs from noon on 1 April to noon on the next 1 April, and the count belongs to the registration, so nights sold on every website add up together.
That is why a minpaku can show closed dates even when it looks empty: once its nights are used, it must close until April. On Minpaku X a closed date says why.
What to look for
Before you book, and again when you arrive:
- The registration or licence number on the listing, with the kind of permission.
- The same number on the sign (標識) by the door.
- Whether the host lives on site; if not, the name of the registered manager who answers at night.
- A phone number for emergencies, and the nearest clinic.
- One price that includes the town's tax, so nothing is asked for at the door.

Questions to ask the host
A legal host answers these without fuss:
- What is your registration or licence number?
- Do you live here? If not, who manages the home?
- Who do I call late at night?
- Will you need my passport at check-in? (If you don't live in Japan, yes: it's the law.)
- Is the town's accommodation tax in the price?
Signs to walk away
Think twice if you see any of these:
- No number anywhere, or a number the host won't show.
- A request to pay outside the booking site, or to send card details by chat, email or WhatsApp.
- "No need for a passport" when you don't live in Japan.
- A price that grows at the door.
How Minpaku X checks
We look at each place's papers (the 届出受理通知書, the sign, or the 許可証) and print the date we checked them beside the number. We don't inspect buildings or fire safety, and until we are registered as a 住宅宿泊仲介業者 we can't check numbers against the national system; the trust page says exactly what we do and don't check.
Questions
Are minpaku legal in Japan?
Yes, when the home is registered under the 2018 minpaku law (住宅宿泊事業法), or the place holds a ryokan licence or a special-zone certificate. An unregistered home taking paying travellers is not legal.
Why can a minpaku open only 180 nights a year?
The law sets the cap so that homes stay homes. The year runs from noon on 1 April, and nights sold on every website count towards the same 180.
Can I check a registration number myself?
Some cities publish lists of registered homes, but there is no single search across Japan. Ask the host for the number, check it matches the sign at the door, and book where the number is shown with the date it was checked.
Why does the host need my passport?
Hosts must keep a guest register. For travellers without an address in Japan, the law asks for nationality and passport number and a copy of the passport. It isn't the host's choice.
What does 'host-occupied' mean?
The host lives in the home and is there while you stay (家主居住型). When the host isn't, the home must be run by a registered property manager, who answers if something goes wrong.
