Bennyb,
If you do go to Nakano - quite accessible from Shinjuku Station by the JR line - don't forget to drop by Jackroad - lots of vintage rolexes there. Also some Pams, and Panerai there.:thumbsup:
WAH! That's same station as fujiya... you can plan ONE full day at Nakano, ONE full day at Shinjuku, ONE full day at Ginza.... that's enough to keep you busy for a few days...
And you can always get a few A&A bags to bring back those Leica gears if you run out of suit cases....
