PhotoMaps has been deleted. It had maps showing where camera shops, photo galleries, etc., were located in Tokyo, Osaka, and Kyoto.
However, the maps were quite old, and some (or much) of the info was out of date. Sorry that I never got around to updating or expanding the maps. If I ever do update them, it will be with an online map like Google Maps (if they ever provide a good online map of Japan in English).
