Bikes DO get stolen in Japan, and it seems to be getting more common. That said if you take sensible precautions and lock in a busy area they shouldbe ok. It certainly doesn't seem to be the problem that it is in london (reading some of the other threads) so basically i wouldn't worry too much.
All roadsigns are in english so navigations not much of a problem. A map should do the trick.
Are you just going to Tokyo, or planning on visiting anywhere else?
