Japanese zip code

I let I download the zip code data which a Japanese postal site shows directly and display it offline.
I have a zip code (there is no hyphen), address half size kana, an address kanji, the ambiguous searchings of the address Romaji (a language, an area English) in same EditText.
In addition, the developer of the application to need address data can use the latest zip code data because I show zip code data by contents provider.
