Where can I buy Soccer jerseys in Japan?

Hi guys,

I'm going on a trip to Japan in November/December (will be basically touring the whole country) and I was wondering if there are any stores (in the bigger cities like Tokyo, Osaka, Hiroshima, etc...) that carry soccer jerseys. As Soccer isn't that much of a big thing in Japan (yet), I'd like to know if there are any sporting good stores that sell them. The team doesn't really matter, I was asked to bring one home for a friend.

Thank you!

Soccer shop Kamo. I have been to the ones in Harajuku and Shinjuku. They sell all kinds of soccer jerseys, local and foreign. They're not cheap!

Soccer is BIG in Japan. Any general sporting goods store (or soccer-only sporting goods store, yes, there are such stores) should sell soccer jerseys.
