Would love to find out about some underground, less turisty things to do in Kyoto? Do they have a certain underground movement, a type of food you couldn't get else where, a club you wouldn't get into without saying the magic words etc.
Would be epic to have some tips.
The only underground movement i know of is geishas tea houses and that's off limits to foreigners unless you have a very good japanese friend..
but if you're in Kyoto one thing to try is the Kaiseki, japan has many traditions like tea preparation and flower arrangements, when it comes to food it's Kaiseki. a 10-15- even 25-course dinner, each dish is exquisitely prepared, decorated and served in the most traditional ways. It does not come cheap, some dinners cost north of 250 usd... but can also be cheap depends on where you go.
My very local/hidden experience in Kyoto was in a small sushi bar off the arcades, coming from shinjo avenue and enterign the arcade it's the second small street on the right, the place is called Tomizushi or locate the japanese sign: とみ寿司 10-12 bar chairs, we met locals who spoke english and the chefs were drunk on sake by the end of the evening :D
Try Kanga-an for a bar run by monks (not sure how true this is anymore).
Kyoto as a whole is pretty touristy. The whole city was deemed culturally important and as such was spared the fire-bombings that other Japanese cities endured in World War II.
I don't know much about "underground movements" etc, but you could certainly try cycling to get around Kyoto.
Food wise, you could probably try (if your personal morals allow) whale or horse meat.
