Visiting Japanese Food Artisans

[Shalmanese]

I'll be visiting Tokyo, Osaka and Kyoto with a friend over the next couple of weeks and I would love to find places that make traditional Japanese foodstuffs like Miso, Tofu, Shoyu, Sake, Soba, Udon etc. that would be willing to give tours or show us around.

Neither of us speak Japanese which I've gathered severely limits our options but we're game to try anyway using a combination of the limited Japanese we have along with sign language.

I'm having a hard time researching places since most of them are very small and don't seem to have much of a web presence but I'd love to get recommendations of places that offer such things.

Thanks!
