If you take the Yamanote line to Ueno there is a old-style shopping area known as Ameyoko by the south exit. In the enclosed shopping area there are at least two knife stores. One of them has a few exclusive Japan-market Spydercos as of last month when I was there. There is another knife store on the same street as Yodabashi Camera. The other knife store that I would highly recommend is "The Edge" in Shibuya. It is rather hard to find and is up a flight of stairs, but usually has a large selection of knives, (6000 plus). The sad part is that the exchange rate makes knives very expensive right now. I only bought two Spydercos on this trip and that was the Mount Everest Worker in plain-edge and a Lg. Goddard, though I won a free Snap-it and Al Mar knife while there. I found those at the G.Sakai factory during the cutlery festival this year. Here is the link. Hope this helps. Have fun. spyderwa
