unless u buy from those roadside store, no way it is cheaper in japan
been 2 japan for holiday few weeks ago and i notice 1 thing, 1st is some items are more expensive while some are cheaper in japan
etc Canon 7D body is selling at $1800 at the camera shop i frequent in japan while a 2nd Hand Nikon 50mm f1.8D lens is selling at $250
2nd thing, at the land of rising sun, bargaining for items is quite hard as prices are fix, if they say $3000, it will be $3000, no less even if you buy 5 set of DSLR from them
as for fujifilm, it will be expensive as it is quite popular for japan, as for major brands like Canon.... well....... =.=!!
