Japan ZIP Codes

Japan uses a “郵便番号” (Yubin Bango) system, which is a seven-digit numeric format like 999-9999, with a hyphen separating the third and fourth digits. Unlike US ZIP codes, which contain 5 digits, Japanese postal codes use a 7-digit format. The first three digits indicate the postal district, and the last four digits specify the delivery area. According to the GeoPostcodes world postal code database, Japan has 142,608 postal codes covering 2,338 regions and 119,002 towns.
