Address format and test coverage: Japan
Synthetic fixtures · Not verified for delivery
An example for Japan
This deterministic example shows the generator’s output for Sakata Shi. Place names and address data retain their destination spelling rather than being translated with the interface. This is a test fixture, not a verified delivery address.
〒999-6834 山形県酒田市 1-10-28
Included regional samples
The current Japan catalog includes 1128 regional samples. City, region and postcode are selected together. This list describes the generator’s coverage, not every locality in the country.

Postal fields in your tests
Preserve postal codes as text, including letters, spaces, hyphens and leading zeros. Examples in the current catalog: 471-0864, 496-8039, 444-2327, 464-0832, 475-0844, 467-8686. A matching format does not confirm delivery.
Use this country in your workflow
Select a region or use any region, then generate 1–1,000 records. Keep the seed, options and generator version unchanged to reproduce a test. Save locally or export CSV, JSON or TXT; browser favorites do not sync across devices.
Generate a Japanese address by prefecture
Choose Japan and one of the 47 prefectures, or leave the region unrestricted. The output separates prefecture, city and postal code so you can map each field into a test form. Generate one record or export up to 1,000. The place catalog is deliberately small: prefecture coverage does not imply coverage of every municipality, neighborhood or building.
Seven-digit postal codes and local address display
The generator displays postal samples in a three-digit, hyphen, four-digit form and prefixes the local block with 〒. That symbol is a display marker, not part of the postalCode value returned by the API. Use Japan Post’s lookup to check an actual postal area. The randomly assembled street/block portion has not been validated against the selected postal code.
Local format does not mean a complete Japanese-script address
For postal samples with an unambiguous Japan Post match, the local view uses Japanese prefecture and municipality labels while the Latin view preserves the catalog labels. Unmatched samples retain the original display. Numeric blocks remain synthetic and omit neighborhood and building details. Neither view is a complete verified postal address or a carrier-certified label.
Useful Japanese address test cases
Keep the postal value as a string, test preservation of the hyphen, and allow Unicode in your own additional fixtures. Keep prefecture and city separate instead of mapping both to a US-style state field. Test building and room inputs independently: this generator does not supply those fields. Names and contact fields are synthetic, with an example.com email and a non-contact phone placeholder. Copy the individual fields for a small form test or use JSON when testing an importer.
