If you're young and still have knees, you really need to climb Misato Machi's 3,333 steps, which lead from a parking lot at the base of a mountain to a temple at its peak (technically, it is a 参道). It's more like 4,000 steps (I've counted them) that pass through lush sugi forest with beautiful glimpses of Yatsushiro. At the top, of course, there is the temple.
I once did the hike, forgot my glasses at the temple, so had to go back to get them. Don't make that mistake, but do do the hike. - William
