Region coverage

Prefecture Filter Notes

The current release covers Tokyo, Osaka, Kyoto, and Hokkaido, which is enough for prefecture filtering demos.

If you expand later, prioritize common prefectures and meaningful city-level differences.

Frequently asked questions

Japan Address FAQ

Why can't the Japan page just swap the country name?

Because Japanese addresses differ from English layouts in ordering, prefecture hierarchy, and block-number notation, so they need their own explanation.

Should a Japan page always show the postal code?

It should if possible. The postal code is one of the clearest cues for recognizing Japanese address structure.

What is the value of prefecture filtering?

It makes Tokyo, Osaka, Kyoto, and other results feel different in both address structure and phone output.
