@ LAST GALLERY, TKO
Akira Takata (known more as a skate photographer) followed the crew around for a while... catching some great candid shots and late night action. The (mega-thin) gallery is decked out in black vinyl, leading you by a rusty old bus-stop seat, to the back room installation of pics. Upstairs is a new and interesting shop worth visiting for those in the trade.
Last Gallery doesn't really have a website, but this blog gets you there sometimes - http://revisit.jugem.jp/ or have a sniff around shirogane eki.
DUMB have some pics up too.
They have good underground stuff on - recently had a zines library, mostly street stuff - by which I mean grimey tags, not stencil art. Also had the Wanto/Fanta show on last year... QP... Good spot, yo.
