A Ruby gem provides look-up and calculations tool for Japan Shipping Rate.

At present, it supports international and domestic shipping methods:

• With international shipping method is EMS fee = rate + extra charges.
• With domestic (inside Japan) is Yu-Pack fee = domestic rate + extra charges. Only support calculating fee for Kyoto deposite now.

If you are in Rails, add this line to your application's Gemfile:

gem 'jp_shipping_rate'

And then execute:

$bundle

Or install it yourself as:

$gem install jp_shipping_rate

shipping_rate = JPShippingRate.instance

    shipping_rate.international(1500, "US")
    => 8500 # equivalent to 8500 yen

Note: Just support domestic from Kyoto for now.

    shipping_rate.domestic(140, "okinawa")
    # => 3200 (yen)

for EMS rate

    # weight = 3500 (g)
    # region = "asia"
    shipping_rate.international_rate(weight, region)

for JP domestic rate (Yu-pack)

    # size = 120 is total of length, width, height of parcel
    # destination_area = "okinawa" area is based on Japan post service definition.
    shipping_rate.domestic_rate(size, destination_area)

We also provides utility methods, please look at source codes.
