Suzuki-san stopped doing shows in the US many years ago. As for now, you can only order his shoes in Japan and Hong Kong (theArmoury). I believe he doesn't take orders over the phone/mail, but I could be wrong.
Hopefully when the Armoury opens its Tribeca outpost, Koji's shoes would be available in the states again.
In other words I have to go to Japan. Gotcha what about Imai Hiroki? How one order shoes from this shoemaker?
