Frequently Asked Questions (FAQ)

What is this Japanese address generator?

A free tool that randomly generates Japanese-style dummy addresses including postal code, prefecture, city/ward, block number and building. It is useful for creating test data (sample addresses) for development, testing, demos, form/report checks and seeding databases. Generate any number at once and copy or download as CSV.

Are the generated addresses real?

No. The block numbers, building names and room numbers are randomly generated fictional values, and the prefecture / city combinations do not point to any real address. All processing runs entirely in your browser and results are never sent to or stored on a server. The postal code only reproduces the format and is dummy data.

Can it include postal codes and building names?

Yes. Options let you include a postal code (7 digits with a hyphen) and a building name / room number. Copy or download as CSV to import into Excel, spreadsheets or a database. Use it for checking form and report layouts.
