Due to the new law started in Japan on June 15th, 2018, all guests staying must provide the following details before their check-in day. This process allows me to operate legally in Japan as a BnB host. Please be advised that I cannot let you stay if you cannot provide me with these details.
1. Full name of each guest staying (including children) 2. Full home address of each guest 3. Occupation of each guest (student, engineer, housewife etc) 4. Photo of everyone's passport page that shows the name, nationality and passport number.
If you feel uncomfortable giving me the information above (or skeptic), please refer to this website as it's stated that I will need those information.
