Benkei Nana Modori
This is a rock formation along the hiking path to Nyotaisan on Mt. Tsukuba in the city of Tsukuba. The path passes under a giant rock wedged between cliff walls, and it makes hikers uneasy, because it looks unstable, as if it might fall down from overhead. Even the legendary hero Musashibo Benkei is said to have hesitated to pass under it.
