Which properties can obtain a hotel/inn (ryokan) business licence — how to tell before you sign

In short: whether a property can obtain a year-round ryokan/hotel business licence turns on three points checked before you sign. (1) Does the zoning allow a "hotel or inn" (Building Standards Act, Appended Table 2)? (2) Can it meet the structural standards of the Ryokan Business Act enforcement order — guest-room floor area, and a front desk or an ICT substitute? (3) Can it carry the fire-service equipment required of a Fire Service Act Enforcement Order Appended Table 1, item (5)(a) property, such as an automatic fire alarm? This is a different yardstick from minpaku, which is capped at 180 nights a year.

"Minpaku is capped at 180 nights a year and the numbers do not work, so I want to look for a property on the premise of a year-round ryokan business licence." We hear this more and more. Yet minpaku, special-zone minpaku, and the ryokan business each demand different things of the property. This article is for anyone wanting to start a small hotel, inn, or guesthouse as a business, and sets out how to tell — before signing — whether a building can obtain a ryokan/hotel business licence.

How do the property requirements differ between the ryokan business and minpaku?

The regulatory frame differs first: whether there is a cap on nights, and which law governs the property.

Scheme	Governing law	Cap on nights	Procedure
Ryokan business (ryokan/hotel business)	Ryokan Business Act (Act No. 138 of 1948), Art. 3(1)	None (year-round)	Licence from the prefectural governor etc.
Housing accommodation business (minpaku)	Housing Accommodation Business Act (Act No. 65 of 2017), Art. 2(3)	180 nights a year	Notification to the governor etc.
Special-zone minpaku	National Strategic Special Zones Act (Act No. 107 of 2013), Art. 13	Minimum stay set by local ordinance (e.g. 2 nights/3 days)	Certification by the governor etc.

Push "I want to run it year-round" to its conclusion and the choice narrows to a ryokan business licence. By the amendment under Act No. 84 of 2017 (in force 15 June 2018), the Ryokan Business Act merged the former "hotel business" and "inn business" into a single "ryokan/hotel business" and abolished the minimum room counts (10 rooms for a hotel, 5 for an inn). You can now aim for a ryokan/hotel business licence with a single room.

The property conditions for minpaku are set out in Which properties qualify for minpaku. This article goes one step further, to whether a building can obtain a year-round ryokan business licence.

Which zoning districts allow a ryokan/hotel business?

A facility licensed for the ryokan business is treated under the Building Standards Act as a "hotel or inn," and is subject to zoning limits. This is a major difference from minpaku, which is treated as housing and is possible under certain conditions even in residential-only districts.

Under Appended Table 2 of the Building Standards Act (Act No. 201 of 1950), the districts where a "hotel or inn" may and may not be built are as follows.

Zoning district	Hotel/inn	Note
Category 1 / 2 exclusively low-rise residential	Not allowed	Not permitted in Appended Table 2
Category 1 / 2 exclusively medium/high-rise residential	Not allowed	Same
Agricultural-residential	Not allowed	Same
Category 1 residential	Allowed (floor area 3,000㎡ or less)	Over 3,000㎡ not allowed, Table 2 (he)
Category 2 residential / quasi-residential	Allowed	—
Neighbourhood commercial / commercial / quasi-industrial	Allowed	—
Industrial / exclusively industrial	Not allowed	Not permitted in Appended Table 2

Turning a detached house in a residential-only district "straight into an inn" is generally not possible. Zoning is fixed by the property's location and cannot be changed afterwards. Check the zoning of a candidate site in the city-planning information first.

Is a front desk mandatory, or is an ICT substitute allowed?

A "front desk" (genkan chōba) and its dimensions used to be required. The amendment in force on 15 June 2018 abolished the dimensional rule and allows not installing a front desk, under certain conditions.

The structural standards for the ryokan/hotel business under Article 1 of the Ryokan Business Act enforcement order (Cabinet Order No. 152 of 1957) require, in principle, a front desk suited to meeting the person seeking to stay — but permit measures in its place where the operator has in place a system for prompt response in emergencies such as an accident and other measures needed to secure guests' safety. In practice, a setup that uses ICT (information and communication technology) such as a video call or a tablet to verify identity and grasp comings and goings on a par with in-person handling is treated as the substitute.

Do not, however, jump to "so no front desk is needed." Even for unmanned operation, confirm with the local authority (public health centre) before signing whether the following can be met, in both the property and the operation.

Point	Confirm before signing
Identity verification	Communications, power, and space to install ICT equipment
Grasping comings and goings	A structure that lets you install cameras or lock management at entrances
Emergency response	A system (distance, staffing) to reach the site for accidents or sudden illness
Guest register	An operation that keeps an accurate record and retains it

The concrete operation of the front desk and its ICT substitute varies by the local ryokan-business ordinance and guidelines. This article is general information; check individual feasibility with the competent public health centre and with the administrative scrivener we work with.

What to confirm before signing on fire equipment and the Building Standards Act use

A hotel or inn falls under item (5)(a) of Appended Table 1 of the Fire Service Act (Act No. 186 of 1948) / Fire Service Act Enforcement Order (Cabinet Order No. 37 of 1961) — "inns, hotels, lodging houses and the like." This is a designated fire-prevention property where an unspecified number of people stay, and heavier fire equipment is required than for a dwelling.

Item to confirm	Basis / benchmark
Automatic fire alarm	Enforcement Order Art. 21; required for (5)(a) by floor area etc.
Guide lights / guide signs	Enforcement Order Art. 26
Fire extinguishers, sprinklers, etc.	Requirement varies by scale and number of storeys
Confirmation for change of use	Building Standards Act Arts. 87 and 6; for a "hotel or inn" (special building), confirmation is needed where that use exceeds 200㎡

Where a dwelling or office is converted to a hotel or inn, if the floor area for that use exceeds 200㎡, confirmation is required under Article 87 of the Building Standards Act. The existing building's legal compliance (whether an inspection certificate exists, whether it is a nonconforming existing building) is also a point to confirm first, as a premise for the ryokan licence.

Who obtains the licence, and in what order (the separation of engagements)

A ryokan business moves the property, the licence, the building, and the fire side all at once. Deciding who does what in advance keeps the order from stalling.

Role	Who
Brokerage of the sale or lease; survey of compliance and terms	Yotsuba Real Estate Co., Ltd. (licensed real estate agent, Tokyo Governor (1) No. 113304)
Preparation and filing of the ryokan licence application	Yotsuba Administrative Scrivener Office (the firm we work with)
Confirmation for change of use; architectural design	Architect / designated confirmation and inspection body
Fire-law compliance; fire equipment	Competent fire station / fire-equipment engineer

Yotsuba Real Estate Co., Ltd. and Yotsuba Administrative Scrivener Office are two independent business entities, engaged separately and directly by you. We neither pay nor accept referral fees or introduction commissions. The architect, the designated confirmation and inspection body, and the fire-equipment engineer are each engaged by you directly as well.

The flow of the ryokan licence application itself (the difference between ryokan/hotel and simple-lodging businesses, and the order of filing) is set out on the administrative scrivener side in How to apply for a ryokan (simple lodging) licence. For the notification requirements of minpaku, see The notification requirements for housing accommodation. Consultation is free.

Frequently asked questions

Q. Can I buy a detached house in a residential-only district and turn it into an inn?
A. Generally no. A facility licensed for the ryokan business is treated as a "hotel or inn" under the Building Standards Act and cannot be built in Category 1/2 exclusively low-rise or medium/high-rise residential districts or in the agricultural-residential district (Appended Table 2). The same building, run as minpaku within 180 nights a year, may be possible as housing even in a residential-only district. If year-round operation is the premise, check the zoning first.

Q. Can I run it unmanned, without a front desk?
A. The amendment in force on 15 June 2018 abolished the front-desk dimensional rule and allows operating without one under certain conditions. The premises are that ICT etc. can verify identity and grasp comings and goings on a par with in-person handling, and that there is a system to respond promptly in emergencies. Feasibility varies by the local ordinance and guidelines, so check with the competent public health centre and an administrative scrivener.

Q. From how many rooms can I obtain a ryokan business licence?
A. The amendment in force on 15 June 2018 abolished the minimum room counts (10 for a hotel, 5 for an inn). You can aim for a ryokan/hotel business licence from a single room. The guest-room floor area, however, must be at least 9㎡ for a room with a bed and at least 7㎡ for other rooms, under Article 1 of the enforcement order.

Q. When converting a former office into an inn, is a confirmation application needed?
A. A "hotel or inn" is a special building under the Building Standards Act, and a change of use exceeding 200㎡ for that use requires confirmation under Article 87. Even at 200㎡ or less, fire equipment must be reviewed separately. Together with whether the existing building has an inspection certificate and its nonconforming status, confirm with an architect and the competent fire station before signing.
