Japan's Postal Code Format

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.
  • Postal Code Format: 999-9999

    • Seven-digit numeric format with a hyphen after the third digit
    • First three digits = postal district; last four digits = delivery area
    • Optimized for routing rather than strict alignment with administrative divisions
    • 142,608 postal codes covering 2,338 regions and 119,002 towns

    Regional Examples:

    • 100-0001 - Chiyoda, Tokyo
    • 530-0001 - Osaka, Osaka Prefecture
    • 460-0001 - Nagoya, Aichi Prefecture
    • 060-0001 - Sapporo, Hokkaido
  • Structure of Postal Codes

    • Format: 7-digit numeric with a hyphen (e.g., 100-0001).
    • Hierarchical levels: First three digits = postal district; last four digits = local delivery area. Codes may overlap municipalities for routing efficiency.
    • Key challenges: Some postal codes cover multiple administrative units; business-only ZIPs require distinct handling.
  • Management & Authority

    • Primary postal authority: Japan Post.
    • Update frequency: Frequent releases by Japan Post; integrated into GeoPostcodes 1–2 times per year.
  • Addressing Standards

    • Common address format: Postal code → Prefecture → Municipality (city/ward/district) → Town/Village → *Aza/Oaza* → Block → Building number.
    • Administrative divisions used: Prefectures (47), municipalities, towns/villages, *Oaza* and *Aza* subdivisions.
    • Notes: Tokyo’s 23 wards act as special municipalities directly under the prefecture, unlike elsewhere in Japan.
  • Special Characteristics

    • No traditional street names; addresses rely on block chome-ban-go and building numbers.
    • Business postal codes may not correspond to the physical location of delivery.
    • Japanese suffixes (e.g., “shi” = city, “ku” = ward, “gun” = district) are included in native data but removed in Romanized formats.
    • Tokyo’s wards are exceptions in the hierarchy, functioning at a higher administrative level than standard wards.
