If you’ve registered a property under Japan’s Minpaku Act (住宅宿泊事業法, often called 民泊新法), there’s a good chance you’re not actually allowed to run it entirely on your own. Depending on whether you’re on hand while guests are staying — and how many rooms you’re renting out — the law may require you to hand day-to-day operations to a registered third party called a 住宅宿泊管理業者, a registered management business operator.

This trips up a lot of new hosts, especially overseas owners who assume that hiring “a co-host” satisfies the requirement. It doesn’t, unless that co-host is actually registered with the national government. Here’s what the rule actually says and when it kicks in.

TL;DR

  • Under the Minpaku Act, hosts who are absent while guests are staying (beyond a temporary absence, with narrow exceptions) or who use more than five rooms (six or more) for the lodging business must delegate operations to a registered 住宅宿泊管理業者 — an informal co-host does not satisfy this.
  • Registration for management businesses is done nationally through MLIT (国土交通省), separate from the prefectural/health-center notification you file for the property itself.
  • A registered manager must demonstrate the operational and compliance capacity MLIT requires — including a structure for complaint handling and remote response, shown through qualifying experience, training, or registrations such as 宅建士 or 管理業務主任者 — and takes on legal responsibility for guest safety, complaint response, and information disclosure. It’s a compliance role, not just a booking-calendar service.
  • Overseas owners will usually need one, since being present while guests are staying isn’t something you can do from abroad.
  • Fee structures vary by operator, so confirm the written remuneration, payment timing/method, separately charged costs, responsibility/exemptions, and contract period, renewal, and cancellation terms before signing.

What Is a Registered Management Business Under Japan’s Minpaku Law?

A registered management business (住宅宿泊管理業者) is a company or individual registered with Japan’s Minister of Land, Infrastructure, Transport and Tourism (MLIT) to operate a minpaku property on behalf of the host. Applications are submitted to the regional development bureau (or equivalent authority) with jurisdiction over the operator’s main office. It’s a distinct legal category from the property notification itself — when you register a listing under the Minpaku Act, that filing goes through your local prefecture or health center. The management business registration is a separate, national registration, and it’s what lets a third party legally take on operational responsibility for a property they don’t own.

This is different from a simple co-hosting arrangement, which we’ve written about before for overseas owners. An informal co-host can help with messaging and cleaning coordination, but only a registered management business can legally satisfy the operational-delegation requirement under the Act.

When Do You Actually Need One?

You need a registered management business if you’ll be absent from the property while guests are staying (beyond a temporary absence), or if you use more than five rooms (six or more) for the lodging business. The Minpaku Act’s default assumption is that the host is on hand while guests are staying and handles operations directly — guest check-in, safety and sanitation upkeep, complaint response, required guest information (evacuation routes, noise rules, neighborhood etiquette). If that’s not realistically true for your situation, the law requires you to delegate those duties to a registered operator instead of doing it informally.

The two most common triggers are:

  • You’re absent while guests are staying. Delegation is required unless the absence is temporary, or unless your home base is in the same building/site as the property (or adjacent to it) so that you can perceive nuisance impacts and respond, and you’re personally managing five rooms or fewer. A host who is itself a registered 住宅宿泊管理業者 can also self-manage under this exception. This covers most overseas owners by default, since being present for every guest stay isn’t practical from abroad.
  • You use more than five rooms (six or more) for the lodging business. Even a host who is present for every stay is required to bring in a registered manager once the room count exceeds five.

If neither applies — you’re present while guests are staying (or qualify for the narrow exception above) and use five rooms or fewer — you can self-manage without hiring a registered operator.

How Do You Find and Vet a Registered Manager?

You vet a registered manager the same way you’d vet any regulated professional: by confirming the registration, not just taking their word for it. MLIT maintains a public registry of registered 住宅宿泊管理業者, and a legitimate operator will have a registration number they can show you without hesitation. To register, an operator must also demonstrate the system needed to perform management duties properly — legal-compliance capacity and an operational structure for handling complaints and responding remotely. Depending on the applicant type, this is shown through registered practical training, two or more years of relevant housing transaction/management experience, qualifying registrations such as 宅地建物取引士 (宅建士), 管理業務主任者, or 賃貸不動産経営管理士証明, a qualifying employee, or qualifying corporate registration — so it’s worth asking how the operator satisfies this requirement.

Beyond the registration check, treat the relationship like any vendor contract: get the scope of work in writing (guest communication, cleaning coordination, complaint handling, incident response), and confirm who’s accountable if something goes wrong with a guest. Fee structures vary by operator, so before signing, get the written remuneration, payment timing and method, any separately billed costs, responsibility and exemption terms, and the contract period, renewal, and cancellation terms — these are items MLIT requires to be disclosed in pre-contract and contract documents.

For overseas owners, a registered management contract can cover both day-to-day operations and the statutory delegation requirement; confirm the operator’s registration number and contract scope before operating. It’s also worth reviewing any prefectural ordinances that apply to your property — they can add local operational restrictions on top of the national rules.

FAQ

Q: Can I just ask a friend or informal co-host to manage my minpaku property instead of hiring a registered business?

No, not if you’re legally required to delegate management. If you’ll be absent while guests are staying (beyond a temporary absence, and without qualifying for the narrow on-site exception) or you use more than five rooms (six or more), the Minpaku Act requires delegation specifically to a registered 住宅宿泊管理業者 — an informal arrangement with someone who isn’t registered doesn’t satisfy the requirement, regardless of how capable they are.

Q: Is the management business registration the same as my minpaku property notification?

No. The property notification (住宅宿泊事業の届出) is filed with your prefecture or local health center and registers the property itself. The management business registration (住宅宿泊管理業者登録) is a separate national registration issued by MLIT that authorizes a company or individual to operate properties on behalf of hosts.

Q: What happens if I’m required to use a registered manager but don’t?

Operating without the required delegation violates the Act’s Article 11 delegation duty and can result in a fine of up to ¥500,000 under Article 75. Separately, for violations of laws or administrative orders tied to the business, the prefectural governor can order a business suspension of up to one year, or order the business abolished, under Article 16. Since enforcement and specifics can vary by case, confirm your obligations with your local government office or a qualified professional before you start operating.
