Frequently Asked Questions

Too many tourists. I haven't been out much this past 10 years in Japan. It was a shock. The area is picturesque, and a nice drive, lots of winding roads (if you like that sort of thing). The actual area around the one little rocky outcrop, it's your regular fare of touristy shops. Nothing I would write home about. The boat rides were also busy. I don't really see it as a too relaxing. I think there are better places to enjoy the water and solitude.

It is an unusual terrain with a series of huge rock formations. There are many people near the boat pier, but as you move away from that area, the number of people decreases. It is a very relaxing place rich in nature. The kids enjoyed their rocky adventure. We can find many tadpoles and frogs here. The view of the boats on the river is also beautiful. The boats are very popular and you may have to wait in line for quite a while to get tickets.

Scenic spot with rock formations and a cool river. You can buy tickets for rafting and riding a boat but the lines are long.
