How to Write a Japanese Address
Japanese online shopping, hotel booking, postcards, envelopes, and delivery forms often require postal code, prefecture, city, street block, building name, and room number.
Who This Helps
- People entering delivery addresses for Japanese online shopping
- People booking hotels, courier delivery, or redelivery
- People avoiding failed delivery caused by missing room details
Practical Points
- Postal codes usually have 7 digits, such as 100-0001.
- Confirm prefecture, city/ward, block number, building name, and room number.
- Use the same name and phone number as the recipient information.
- For postcards and envelopes, the stamp is commonly placed at the upper right, including horizontal layouts.
- Missing building or room details can cause failed delivery or investigation.
Common Envelope Types
| Type | Common Use | Notes |
|---|---|---|
| Long envelope | Letters, invoices, folded A4 documents | Can be written vertically or horizontally. |
| Large document envelope | A4 documents, contracts, printed materials | Good for unfolded documents; postage may be higher. |
| Western-style envelope | Invitations, cards, horizontal letters | Works naturally with horizontal writing; the stamp is still clear at the upper right. |
| White envelope | Formal documents, resumes, applications | Keep it clean and simple. |
| Kraft envelope | Daily documents, office mail, business materials | Common in business, but white envelopes may be better for formal applications. |
