Kamo Ikebukuro

If you’re looking for a local jersey, Kamo is the place to go. Instead of getting knick knacks or whatever to commemorate visiting a city, I like to get a shirt from the local side.
However, the J-​League isn’t like Serie A or the EPL when trying to buy a team kit in the city’s hometown. Well, at least Tokyo isn’t. So it’s not just like popping into any store and picking up merchandise.
Kamo has everything you would need on the international side — I came during the World Cup and they had jerseys from every team (except the USA — what’s up with that?!) but more importantly they had kits from just about every J-​League team, both home and away (and some 3^rd kits). But beware, there are no discounts to be had here. A kit will average about ¥10,000 so you won’t be getting a deal.
There are also scarves and iPhone cases and all sorts of other things for your favorite team. If you need football merchandise in Tokyo, this is the place to go.

Every thing you need from J-​league jerseys to European clubs Kamo has it all. In support of Japan picked up a very sturdy Japanese National Team iPhone 5/​5s case for 3,300yen (Made in Japan!). There were other cases but most were made in China and a bit flimsy.
Lots of great price points and many soccer related accessories. Give it a try~
