Check out The Casual on youtube before heading over there. (He sells streetwear tours where he personally takes you to some crazy places so maybe hit him up?)
Couple of places i wish i could go
Bape(Dont waste your time with AAPE)
THE CONVENI(If you can get there lmao)
Wormtokyo(Think flight club but rare shit)
Laila(More expensive/high end clothing)
Kapital(IDK if they have a store but try to)
Dover Street Market
I really appreciate how he can tastefully-ish do tacky shit. His work at Moschino goes in line with the vision or the brand definitely. His adidas collabs where nice, but some where just too much(think panda heads).
Over all, ill pass but i dont dislike nor hate his work.
