Ioki Cave — Attraction in Aki

COOL place. It can be tricky to find. There is a sign on the road pointing to it, but DONT turn the car that way. Roads are narrow and there’s no parking anyway. Across the road there is some kind of cave center you can park at. I missed it and parked down the road at the convenience store.
