finding good street fashion shops for my labels

dear all,
i am new to this forum and has never been to japan.
But, i plan for expansion of business for the UK street fashion labels I am distributing in Asia now.

Do you have any recommendations which shops I should approach? My stuffs are tees and sweatshirts... very cutting edge street style.

I know Japan is a very big country.

It would be nice to hear your reply as you know alot more about Japan than me.

thanz.

In Tokyo, I would recommend Harajuku and Shimokitazawa, although be warned a lot of the clothes will be imported and used (often several years old) from the US. You'll probably find more "new" stuff in Harajuku. To an extent, Shibuya wouldn't be bad to walk around in, but there are a few designer places as well.

Avoid Ginza if you're into urban looking wear.
