About this app

It has a flexible search function. You can search by postal code, old postal code, place name, address, and reading kana (hiragana/katakana).
All cities, wards, towns, and villages in Japan are organized hierarchically, so you can find the place name you are looking for with intuitive operations.
It is built based on the postal code information released by Japan Post Co., Ltd. (This app is not related to Japan Post Co., Ltd. in any way.)
