"I want to run a minpaku in Japan — but do I need to follow the Ryokan Business Act or the Minpaku New Law?"

Great question, and you're not alone in asking it! In this article, we'll walk you through how each law works, which one applies to your property, and how to choose the right path for your rental business — all based on the latest 2026 information.

The short answer? It depends on your location and how you want to operate. Read on to find the right fit for you!

Ryokan Business Act vs. Minpaku New Law: Which Should You Choose?

When starting a vacation rental in Japan, the law you need to follow depends on where your property is and how you plan to run it.

Under the Ryokan Business Act, your property is classified as a "ryokan, hotel, or simple lodging facility." Under the Minpaku New Law, you're renting out a regular home as a short-term rental.

Both laws require you to meet safety, hygiene, and neighbor-consideration standards — and operating without proper registration or permits is not an option!

What Each Law Actually Covers

Ryokan Business Act

This law governs hotels, ryokan, and other lodging facilities in Japan. It sets strict standards to ensure guests stay somewhere safe and clean. The barrier to entry is higher, but the big payoff is that you can operate 365 days a year with no cap on operating days.

Minpaku New Law (Housing Accommodation Business Act)

Enacted in 2018, this law was designed to make it easier for homeowners to rent out their homes to travelers on a short-term basis. The facility requirements are much lighter than the Ryokan Business Act, and you can operate in residential areas — making it a much more accessible starting point.

The catch? The "180-day rule" limits you to 180 operating days per year. For the remaining days, some operators shift to monthly or weekly rentals to keep income flowing.

⚠️ 2026 update: Cities like Tokyo and Osaka have been introducing additional local ordinances ("jorei") on top of the national Minpaku New Law — including weekday bans or even stricter caps on operating days. Always check your local municipality's rules before you start!

Which One Is Right for You?

Start by checking your property's zoning classification (more on that below). If both laws apply to your zone, here's how to think about it:

For example: if you want to rent out a stylish city apartment, the Minpaku New Law is probably the easier route. But if you're running a resort villa year-round and want stable income, the Ryokan Business Act is the stronger foundation.

Rules for Operating Under the Ryokan Business Act

Zoning Requirements

Japan's zoning system determines what kinds of buildings and activities are allowed in each area. Operating under the Ryokan Business Act isn't possible in strictly residential zones — you'll generally need to be in a commercial, quasi-industrial, or mixed-use zone.

The Minpaku New Law is more flexible: it's allowed in almost all zones except exclusively industrial areas.

One more thing to note: if your property is within about 100 meters of a school or childcare facility, your permit may be denied on environmental grounds. Adding a visual barrier may help in some cases — check with your local authority to be sure!

Building Use Classification

Under the Ryokan Business Act, your property must be classified as a "ryokan or hotel" under Japan's Building Standards Act. That said, if your property is 200㎡ or smaller, you may be able to start operating without going through complex usage-change procedures — though zoning rules still apply!

Fire Safety Requirements

Under the Ryokan Business Act:

Under the Minpaku New Law:

※ If you're running an owner-absent minpaku, the same fire safety standards as hotels/ryokan apply.

Front Desk Requirements

Since Japan's 2018 revision to the Ryokan Business Act, small lodging facilities are no longer required to have a physical front desk — as long as you have an adequate alternative system in place (smart locks, video monitoring, AI check-in, etc.).

That said, local rules vary. For example, Chuo Ward in Tokyo still requires a front desk. Always check with your municipality before assuming you can go fully unmanned!

What Happens If You Operate Without a Permit?

Penalty Overview

Beyond the fines, the real risk is being removed from OTA platforms and facing neighborhood disputes that lead to forced closure. The total business impact can easily be many times the fine itself — so it's always worth doing things by the book.

How to Stay Compliant

1. Talk to your local authority first: Consult your local health center or relevant municipal office before you start — local rules vary

2. Prepare all required documents: Proof of ownership, safety inspection reports, insurance coverage, etc.

3. Welcome inspections: Municipal inspections are part of the process — embrace them as a way to confirm you're guest-ready

4. Consider hiring a specialist: A licensed administrative scrivener (行政書士) can make the application process much smoother

Once your Ryokan Business Act permit is approved, you'll receive an official "Ryokan Business Operating Permit" — which you'll need to display at your property.

Why the Ryokan Business Act Can Be a Smart Choice

Yes, the bar is higher — but the benefits can be well worth it!

Year-Round Operations

No 180-day cap. You can welcome guests every day of the year, maximize occupancy during peak seasons, and build a stable, predictable revenue stream.

Broader OTA Access

Some OTA platforms only list properties that hold a Ryokan Business Act permit. More listings = more visibility = more bookings.

Flexible Guest Capacity

You can accommodate guests based on your room count — great for families, group tours, sports teams, or corporate retreats. Just keep in mind that both the Ryokan Business Act and the Minpaku New Law require at least 3.3㎡ of floor space per guest.

Credibility and Guest Trust

Holding a Ryokan Business Act permit signals quality and safety to guests. It's a trust signal that can lead to higher ratings, more reviews, and repeat bookings.

Easier Access to Local Support

Local governments tend to be more cooperative with licensed lodging operators. That can translate to easier access to subsidies, grant programs, and support networks.

Wrapping Up

Here's the quick summary:

• Ryokan Business Act: For operators who want to run a full-time, year-round lodging business. Higher barrier, but bigger upside.

• Minpaku New Law: For those starting small — side income, empty home use, or combining with personal use. Easier to start, but capped at 180 days/year.

• Local ordinances: In 2026, more cities are layering additional restrictions on top of national rules. Always verify local rules before launching.
