Earlier this year while I was staying in Ginza for the weekend a spring popped inside one of my lenses. I have some experience repairing and rebuilding mechanical SLRs (not so much lenses) but without any tools or parts I was hoping to find a repair shop nearby that wouldn't break the bank. Ended up finding a pic on Flickr from someone who had the same issue a few years ago of him and the repairman with his Victor Hasselblad diploma, and his business card. Totally random place on the 8th floor in San-chome, but he was a great guy who I never would've met if not for that post.
