JapaneseAddressParser is a Ruby gem that parses Japanese address. To detect the address, it uses geolonia/japanese-addresses (https://github.com/geolonia/japanese-addresses) CSV data.

This gem provides a plugin for Sprockets to transpile modern javascript using Babel. Unlike other options in the sprockets ecosystem, it works with the latest version of Babel and any plugins/presets you install. A primary use case for this gem is to facilitate incremental migration of a large Sprockets-powered javascript codebase to ES6 modules by transforming them to UMD modules that preserve your existing global variable references (hence the name: Babel + UMD = BumbleD). That said, this gem can be used for general purpose babel transpilation within the Sprockets pipeline.
