Most short-term rental operators in Japan know vaguely that they’re supposed to check guest IDs.

Not because the requirements are extreme, but because they sit across three different pieces of legislation — and nobody gives you a single checklist. You piece it together from the fire department, the ward office, and the building management company, often getting slightly different answers from each.
