Renting Your Japanese House on Airbnb: The Minpaku Rules

Plenty of overseas owners let their Japanese house to short-stay guests, and the rules are clear and workable. They are also more specific than the "just list it on Airbnb" advice suggests, and for an owner living abroad there's one requirement that shapes the whole operation. Here is how it works, what it costs, and the two numbers that decide whether a rural minpaku makes money.

Three legal routes

The private lodging law, or minpaku route. Introduced in 2018, this is the route almost every foreign owner uses. You notify the prefecture, you get a notification number, and you may host paying guests for up to 180 nights a year. No licence, no discretionary approval. The house must be a residence with a kitchen, bath, toilet and washbasin, and it must actually be used as a residence: lived in, on the rental market, or used at least once a year as a second home. A holiday house you visit every summer qualifies. A newly built investment flat with no residential history does not.

A hotel business licence. For unlimited nights, you apply to the public health office for a licence, usually in the "simple lodging" category. It's a real permit with real conditions on the building, fire equipment and zoning, and it isn't available in some residential zones. For a single house it's usually more trouble than it's worth unless you are running it as a proper business year-round.

Special zone minpaku. A handful of designated areas run their own scheme with different day limits. The best known, Osaka's, is closing to new operators in 2026. Mention it only so you recognise the term.

For a house, the minpaku route is the one, and the rest of this guide is about it.

The 180 nights, and how they're counted

The year runs from noon on 1 April to noon on the following 1 April. Nights count per house, not per owner, so if you buy a property that is already operating, the nights its previous owner hosted this year are yours. Get the figure in writing before contract.

For most owners the cap isn't the constraint it sounds like. A ski house in Niigata runs a season of around 100 nights against the 180 available. A beach house in Chiba fills summer and the long weekends. The cap bites on city apartments trying to run year-round, which is not the property most of our clients own.

Why an absent owner must appoint a manager

This is the requirement that shapes everything. The law puts seven statutory duties on the operator: keeping the house clean and hygienic, maintaining safety equipment, providing guidance for foreign guests, keeping a guest register for three years, briefing guests on rubbish and noise rules, handling complaints including attending in person, and maintaining the property. If you don't live at or next to the house during stays, you can't do those yourself, and the law says you must entrust all of them, as a package, to a single registered private lodging manager. You can't keep some and outsource others, and you can't split them between two firms.

What stays with you is the commercial side: the listing, pricing, calendar, guest messaging about bookings, and the money. Many owners run all of that themselves and pay the manager only for the statutory duties, which is cheaper. Others hand over the lot.

The manager doesn't have to be local. What has to be local is the person who turns up when a guest locks themselves out at midnight or the neighbour complains about noise. Managers routinely subcontract that callout role to a local cleaning firm, which the law allows. So when you choose a manager, the question isn't where their office is; it's who physically attends, and whether that arrangement is already in place for your area.

The manager must be contracted before you file the notification, because the contract is attached to it.

Fire safety

An operator who isn't present during stays puts the house into the lodging category for fire purposes, whatever its size. In practice, for a typical detached house, that means an automatic fire alarm system, which under 300 square metres can be the wireless, battery-powered type that an owner can fit without a licensed installer. Exit signage is often waived for a small house, and an extinguisher is required from 150 square metres. The fire department inspects and issues a certificate, which is attached to the notification.

On a 40 square metre single-storey house we handled recently, three detectors covered it, the paperwork ran to six forms, and the whole fire process took about five weeks. Budget the time as much as the money.

One genuinely helpful quirk: a notified minpaku house is treated as a residence under the building code, so there's no change-of-use application and no 200 square metre threshold to worry about. The hotel licence routes don't get that concession.

Local rules

Prefectures and cities can restrict the days or the areas where minpaku operate, and some do. Kyoto is the strictest in Japan and tightening further. Osaka bans it in residential-exclusive zones and near schools on weekdays. Most rural areas add nothing. Since July 2026, municipalities also have national guidance allowing them to prohibit new minpaku altogether, and a house in a town that has done so loses its minpaku capability when it's sold, with no grandfathering. Checking the local position is a ten-minute job before you buy, not after.

Buying a house that already operates

The notification doesn't transfer. The seller files a closure and you file a fresh notification in your own name, with a new number, a new sign on the door and, usually, new fire paperwork if the seller was a resident operator in the lighter fire category. Only one notification can exist for a house at a time, so the two filings are sequential, but with a pre-consultation with the prefecture the gap is days rather than weeks. Ask the seller for the full notification file, the nights hosted this year, and photographs of the fire equipment before you sign.

The two numbers that decide it

Neither is a legal issue. Both kill more rural minpaku plans than the law does.

Cleaning. It doesn't scale down with remoteness; it scales up. In the Minamiboso area of Chiba, the cheapest cleaner we could find for a 40 square metre house charged ¥12,000 per clean. For a 180 to 200 square metre farmhouse, expect ¥25,000 to ¥40,000 per turnover, if you can find anyone at all. On a two-night booking at ¥15,000 a night, that's your margin gone.

The callout. Someone has to be able to reach the house within roughly half an hour, at any hour, for the life of the operation. In a town with an existing cleaning and management trade that's a phone call. In a remote area it's the reason a manager declines the job or prices it accordingly.

We model both explicitly in any yield analysis we do for a client. If the numbers work, they work. If they don't, there's a better option.

The alternative that avoids all of it

Furnished rentals of 30 days or more, on a fixed-term lease, sit entirely outside the accommodation laws. No 180-night cap, no notification, no manager, no callout duty, and cleaning only at move-in and move-out. For an owner who lives overseas and has a house somewhere quiet, mid-term letting to remote workers, seasonal staff and long-stay visitors is often the better business and the simpler one. It's the model behind Kichi, our sister platform, which lists furnished houses on 30-day leases and markets them on the owner's behalf for a share of the rent. If your house sits idle for most of the year, it's the way to make it earn without any of the minpaku hassle: no notification, no registered manager, no fire pack, no night count, no callout. It's worth running both models before you commit to either, and if you'd like your house considered for Kichi, say so when you get in touch.

Where we fit

We help clients decide which route a property suits, find and vet a registered manager and a local cleaning and callout arm, handle the fire consultation and the notification, and, if you buy a house that's already operating, manage the handover so you're not dark for a month. The tax side of rental income is covered in the tax representative guide. Talk to us before you buy rather than after; it's the cheapest advice you'll get.
