The Moss Temple
This is a temple you have to write to ask to attend (in japanese). A friend helped me with that. There are a bunch of temples which are themed like "grasshopper temple". Some of theme are open to the public, and some ofthem are practicing buddhist temples - I was politely turned away from one, where a monk asked if I was buddhist and whether I was seeking counsel from a monk. They weren't being jerks, they looked really busy.
