Guest Registers for Minpaku: Rules for Foreign Guests, Retention Periods, and Penalties for Non-Compliance

Guest Registers in Minpaku: A Legal Obligation That Includes Proper Handling of Foreign Guests

If you’re running a minpaku property, maintaining a guest register isn’t optional—it’s a core part of day-to-day compliance. Whether you operate under the Private Lodging Business Act (the “minpaku law”) or the Hotel Business Act, creating and preserving a guest register is a clearly defined legal requirement. Foreign guests require different entry fields, including mandatory passport verification, which makes this an area where oversights happen easily. This article walks through the basics of guest registers in minpaku operations, the practical steps for handling foreign guests, retention periods, and the risks you face if something goes wrong.

What Information Must Be Recorded in a Guest Register

Article 8 of the Private Lodging Business Act requires private lodging business operators to create a guest register. Article 6 of the Hotel Business Act similarly requires inns and hotels to keep one on hand. The specific fields vary slightly depending on your business type, but the following information is universally required.

For Japanese Guests

Name, address, occupation, and contact information are the baseline fields. Under the enforcement regulations of the Private Lodging Business Act, these details are meant to be recorded based on information provided directly by the guest. Even if you’re using an online check-in system, you need to confirm that it’s actually built to capture and store this information properly.

For Foreign Guests

For foreign guests, you’re required to record name, nationality, passport number, and occupation—and you must request to see the passport itself and verify the number before recording it. Article 5 of the Hotel Business Act’s enforcement regulations contains corresponding provisions. In practice, most operators scan or photograph the passport’s photo page and keep it on file, but handling this personal information also requires separate compliance with the Act on the Protection of Personal Information.

Where Foreign Guest Handling Actually Trips Operators Up

Even in properties we manage directly at Stay Buddy, guest register handling for foreign visitors is something that needs repeated checking. In one case, a self check-in system the owner had installed was designed around Japanese-language input, and the nationality field—entered in Romaji by foreign guests—was treated as “optional,” letting guests submit the form with it left blank. When we reviewed the register after checkout, we found that several passport number fields were empty. We immediately changed the system settings to make these fields mandatory, so guests couldn’t proceed to the next step without filling them in. Gaps like this emerge precisely because people assume that simply installing a tool means the job is done.

There’s also the question of identity verification accuracy when passport number confirmation happens entirely online—this needs to include matching the guest’s face to their passport photo. The Japan Tourism Agency’s guidelines require identity document verification even for non-face-to-face check-ins, and in some cases, simply having guests type in a number is deemed insufficient.

How Long You Must Keep Guest Registers

The enforcement regulations of the Private Lodging Business Act set the retention period for guest registers at three years. The Hotel Business Act’s enforcement regulations impose the same three-year requirement. If you’re managing records on paper, you’ll need to deal with storage space and the risk of loss, but switching to cloud-based digital management improves both searchability and data integrity. That said, even digital records carry the risk of loss if the storage service you use shuts down, so a regular backup routine is still essential.

Penalties for Incomplete or Missing Guest Registers

Incomplete entries or failure to maintain a guest register can trigger administrative penalties and criminal liability. Under Article 17 of the Private Lodging Business Act, prefectural governors may issue business improvement orders, and in serious cases, this can escalate to a business suspension order under Article 18 of the same law. Under the Hotel Business Act, Article 26 similarly allows prefectural governors to impose a suspension of operations.

On the criminal side, Article 48 of the Private Lodging Business Act establishes penalty provisions for false entries or incomplete registers, which can result in fines depending on the circumstances (the upper limit is specified in that article). “I didn’t know” or “the system wasn’t set up for it” are not valid legal defenses.

Making Guest Register Management Actually Work in Practice

A guest register isn’t something you can just create and file away—it needs to be kept in a state where it can actually be produced on demand. If a government inspector shows up and your staff can’t immediately present the register, your entire management system comes under scrutiny. For the properties we manage, we’ve built in a routine to regularly check whether guest register data is being automatically collected after check-in, and whether the passport number fields for foreign guests have actually been filled in. Oversights tend to happen when volume spikes during busy periods, so we’ve standardized a weekly review process to catch them.
