This is currently underdevelopment..
A PHP 5.4+ address library for Japan’s address/postal system in both English & Japanese. It is powered by Japan Post’s csv dataset.
The library stores, sets and manipulates regions, prefectures and cities, as well as performing a lookup function for full Japanese addresses via it’s postal code (yubin-bango) in either language.
Features:
- Super fast address lookup via postal-code.
- Subdivision translations for all regions, prefectures and cities in Japan with kanji, romaji and English.
- Translation for full Japanese addresses, but limited for special (JIGYOSYO) addresses in English.
- Easy PHP script for updating datasets, with checking current and available new CSV files from Japan Post’s website, as well as downloading the files required.
The dataset for postal-code addresses are stored locally in JSON format. To avoid loading over 50MB of data, the dataset is split in to 1000 JSON files per the first 3 digit postal code. This results in lookup functions being super fast and reducing server resources by only loading a maximum file size of 650KB. The dataset can be generated/updated via the locally stored script (/scripts/update-repository.php) by using Japan Post’s CSV files which are downloaded automatically when outdated.
The datasets for subdivisions are stored locally in JSON format, from Google's Address Data Service and also Japan Post’s CSV files (http://www.post.japanpost.jp/zipcode/dl/kogaki/zip/ken_all.zip).
