Format guide
Japanese address order
Japanese addresses usually start with a 〒 postcode (3 digits-4 digits), then prefecture, municipality/ward (ku in Tokyo), chome-banchi, and building/room. Full-format lines keep Japanese kanji for form testing.
Typical line order
| 〒 postcode | 3 digits + hyphen + 4 digits; test full-width/half-width |
|---|---|
| Prefecture | e.g. 東京都, 大阪府, 神奈川県 |
| City / ward | Tokyo 23 wards write 新宿区 etc.; designated cities write 横浜市西区 |
| Chome-banchi | Town name + chome-ban-go |
| Phone | +81; Tokyo landline often +81 3 (fictional test numbers here) |
Postal codes
Japan postcodes use 3 digits, a hyphen, and 4 digits (e.g. 160-0022). This site binds prefixes and curated last-4 candidates to the ward/municipality. Samples are fictional—not Japan Post delivery points.
Form testing checklist
Validate 〒xxx-xxxx; keep prefecture and municipality linked; cover address splits and width variants. For more address form cases, see US address form test cases
Typical use cases
Useful for 〒 regex, prefecture dropdowns, address1/address2 splits, full-width/half-width, and +81 phones (Tokyo landline often +81 3). Do not use for shipping, registration, or payment.
How to use test data
In development you can use these samples to check field length, line breaks, international characters, and responsive layouts. For payment, identity, logistics, or compliance flows, use official sandbox data from your provider—do not submit these samples to live systems.
