Why buy a Japanese booster box?

Japanese booster boxes are a favourite with collectors in the UK. Japanese cards are famous for their print quality and sharp centring, the packs are smaller and cheaper per pack, and Japanese sets often release months before the English version, so you can chase the illustration rares first.

Please note that all cards in this box are printed in Japanese. They are genuine Pokémon cards made by The Pokémon Company in Japan, and they are great for collecting, grading and display.

We check the seal and condition of every product before it is listed, and we pack it with care. If you have a question about a particular product, our team is happy to help before you order, so you can buy with confidence.
