How Japanese Addresses Work
Common mistakes:
- • Writing address in Western order (small to large) — wrong for Japan Post
- • Forgetting the postal code (\u3012XXX-XXXX) — causes delivery delays
- • Using romaji only — Japanese carriers need kanji addresses
- • Forgetting apartment/room number (\u53f7\u5ba4)
FAQ
Q: How do I write a Japanese address correctly?
Japanese addresses go from large to small: postal code → prefecture → city/ward → town → block → building → room → name. For example: 〒150-0002 東京都渋谷区渋谷2丁目3-15 メゾン渋谷402号室 山田太郎. This is the opposite order from Western addresses.
Q: What order do Japanese addresses go in?
Japanese addresses go from biggest to smallest: Country → Prefecture → City/Ward → Town/District → Block → Building → Room → Name. International mail reverses this to Name → Building → Block → Town → City → Prefecture → Postal Code → JAPAN.
Q: How do I find my Japanese postal code?
Japanese postal codes are 7 digits formatted as XXX-XXXX. You can find your postal code on your residence card, on mail you have received, or by searching Japan Post's postal code lookup at JP Post website. Enter your city and ward to find the code.
