The Pokémon Company has launched a Pokémon Store on Amazon Japan. Many of the items that are found at the Japanese Pokémon Centers can now be purchased online. 10,000+ items are available for purchase and most of them have free shipping inside of Japan. Many of these items can also be sent worldwide, so now fans from around the world that would like to get Pokémon merchandise from a trusted retailer can now get them from Amazon. The shipping rates depend on the item and the location it is being sent to.
