Nao mentioned to me that the Ueno Green Club building is the one that a Fall shohin show takes place in. We have attended the November shohin show a couple times, and the vendor sales area was the outside area for trees and plant material and the alcove for tools and other accents, so for the entire three story building *and* the exterior to be full of vendors will be some serously mind blowing shopping. The tour is a really good value with lodging and transportation taken care of (which imo is the fiddliest part of figuring out travel in japan).
