Japan Minpaku Law: What Airbnb Hosts Must Know About Guest ID Rules
Japan minpaku law requires short term rental hosts to collect identifying information from every guest and keep those records on file for three years. This applies whether the property operates under the Private Lodging Business Act (minpaku) or the Hotel Business Act (ryokan gyoho), and it exists so hosts can produce guest records if police or local authorities ever request them.
This article breaks down exactly what information Japan's law requires hosts to collect, how the three year retention rule works in practice, and what Airbnb and vacation rental hosts operating in Japan can do to stay compliant without adding hours of manual paperwork to every check-in.
Key Takeaways
Japan minpaku law requires hosts to collect each guest's name, date of birth, address, occupation, and dates of stay, and to keep those records for three years.
Foreign guests staying at a minpaku or ryokan in Japan must also provide their nationality and passport number as part of the guest register.
Hosts are not required to proactively submit guest records to the Japanese government, but they must be able to produce them if police or local authorities request them.
Digital ID and passport collection tools can help Airbnb hosts in Japan gather and store required guest information as part of the pre-arrival check-in process.
Properties that automate identity verification can achieve up to 93 percent online check-in completion, which can make compliance easier to maintain alongside guest experience.
What Japan's Minpaku Law Requires Hosts to Collect
Under Japan’s guest register requirements, hosts must record each lodger’s full name, date of birth, address, occupation, and the dates of their stay. This obligation applies to minpaku operators under the Private Lodging Business Act as well as traditional ryokan and hotels regulated under the Hotel Business Act. The rule exists primarily as a public safety and identification measure, not as a marketing or guest communication requirement.
For foreign guests, the requirement goes further. Hosts must also collect the guest’s nationality and passport number, and in many cases a photo or scanned copy of the passport itself is expected as supporting documentation. Japanese nationals typically only need to provide their basic contact details, since their identity can already be verified through other means.
Under Japan minpaku law, the guest register a host maintains should typically include:
full legal name
date of birth
home address
occupation
dates of stay
How the Three Year Retention Rule Works
Once a host collects this information, Japan minpaku law requires it to be kept on file for a minimum of three years from the date of the guest’s stay. Hosts do not need to send this information to a government agency as a matter of routine, and there is no requirement to file it with immigration or tax authorities unless specifically asked.
What the law does require is availability on demand. If local police or another authorized government body requests guest records, typically as part of an investigation, a host must be able to produce them promptly. Keeping records only on paper, or scattered across email threads and messaging apps, can make this harder than it needs to be when a request actually comes in.
Hosts who want to stay organized and audit ready over a three year window generally need to plan for:
nationality for foreign guests
passport number for foreign guests
photo or scan of passport
a consistent storage location for every guest record
records that remain retrievable after a booking is closed
Making Guest ID Compliance Part of the Check-in Experience
For Airbnb and vacation rental hosts managing a Japan property remotely, collecting this information manually for every guest can become one more task squeezed into an already busy check-in process. Asking guests to email a passport photo or fill out a paper form on arrival works, but it is easy for records to go missing or stay incomplete.
Digital pre-arrival tools that combine online check-in with ID and passport collection can fold this requirement into a step guests already expect to complete before their stay. Properties that build ID verification into the online check-in flow can achieve up to 93 percent completion before arrival, which can reduce the number of guests a host has to chase down for documentation once they are already on site.
A pre-arrival workflow built around Japan’s guest register requirements can typically combine:
a process for protecting sensitive data from unauthorized access
a way to quickly retrieve a specific guest's file if authorities request it
backups in case of device loss or damage
online check-in with built in ID and passport upload
selfie or biometric verification to confirm the guest matches their ID
secure digital storage that satisfies the three year retention rule
automatic reminders for guests who have not yet completed verification
