Jpostcode CircleCI

A Ruby implementation for Japan postcode.

Installation

Add this line to your application's Gemfile:

gem 'jpostcode'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jpostcode

Usage

Basic one:

address = Jpostcode.find('154-0011')
address.prefecture      # 東京都
address.prefecture_kana # トウキョウト
address.prefecture_code # 13
address.city            # 世田谷区
address.city_kana       # セタガヤク
address.town            # 上馬
address.town_kana       # カミウマ
address.zip_code        # 1540011

When the code covers multiple addresses:

addresses = Jpostcode.find('0110951')
addresses.class # Array
addresses.each do |address|
  puts address.town
end

# => 土崎港相染町
# => 土崎港古川町

Office postcodes are also available:

address = Jpostcode.find('113-8654')
address.prefecture        # 東京都
address.prefecture_kana   # トウキョウト
