Tennoiwa/ Emperor Rock Rock Climbing

A small crag located on hwy 201 west of Akiruno. The cliff ranges from 15 to 25 meters and is a great area for beginners. Tennoiwa is a great place for the beginner to climb in the summer, but will take a couple of days to dry due to the low hanging dense trees. There are two main cliffs here with about 50 routes ranging from 5.7 to 5.12.

There is a very large parking lot across the street from the crag. This is a paid parking area and is mainly for the International Fishing Club down the street. Currently (in 2026), this is a "no-climber parking" and you need to park at "十里木の駐車場", which is located 5 min by bus or 30 min on foot ( rocktopo.net/parking_spots/248 and see "駐車場への行き方を見る"). Keep this in mind.

In 2026, the bathroom is not permitted, either. In an emergency, you must ask permission from the parking attendants.
