Guest Personal Data in Japan: What Short-Term Rental Operators Actually Owe Under the APPI
Every time a guest checks into one of our properties, we log their details in our guest ledger and verify who they are. For foreign guests without a Japan address, that means recording their nationality and passport number and keeping a copy of the passport itself. Multiply that by however many bookings a month, across however many properties, and you’re sitting on a pile of personal data that most small operators never think about as a compliance problem — until something goes wrong.
