Tokyo comtemporary shops and independent boutiques

[Radana]

Hi does anybody know, cool independent shops in Tokyo, which sell high end contemporary fashion. Something like Colette in Paris or Dover Street Market in London? Any suggestions would be welcome, I am going to Tokyo in April (my first visit) and carrying with me a small capsule collection, which I would like to present around. Any contact either directly on to the store/shop or their buyer would be absolutly great.
Many Thanks Radana
