US Address GeneratorJapan Address Format Guide
Japanese postal codes are 7 digits (XXX-XXXX): the first 3 identify a broad area, the last 4 narrow it down to a specific delivery zone. Japan's addressing system is fundamentally different from the Western street-and-house-number model — it uses a block-based system instead. The hierarchy, largest to smallest, is: prefecture → city/ward/town/village → chōme (block number) → banchi (a parcel within that block) → gō (the building number on that parcel) — for example "1 Chōme-2-3 Jinnan, Shibuya City, Tokyo". This block-based numbering, rather than naming streets, is the single most distinctive feature of Japanese addresses, and it's exactly where many internationalized "street address" form fields run into trouble, since a traditional street name usually doesn't exist.
Addresses generated by this tool for Japan are rule-based test data, not backed by a real geographic database. They are intended only for form validation, checkout flow testing, database population, UI prototyping, and localization testing — not for use as a real delivery address or identity proof.
