Try the grilled fish (amego)
I thought this was kind of cool, skewered fish grilled over coals. These are fresh water fish from the Iya River valley of a kind called amego, (ah-meh-go) which I was told can only survive in waters that are absolutely pollution free. They were tasty and so light and delicate that they can be eaten meat, skin, bones and all. I skipped the head.
It seemed like all through rural Japan we would run into just the coolest food, sweet potatoes roasted in a parking lot, buckwheat cookies, just all sorts of stuff. These particular fish were being grilled under the awning of a convenience store.
