Just got back from Osaka, my Japanese home away from home. Didn't swing out to meet Mr. Nagasawa, but did check out the Shimano museum, which was a lot of fun. I keep trying to find the elusive shop with everything there!
Some, mtb heavy, pics of the museum below. Even some pics from the "back room" which the curator was kind enough to grant me access too.
