Kimodameshi

Kimodameshi ( or , ; "testing one's liver"), known in English as a test of courage, is a Japanese activity in which people explore frightening and potentially dangerous places to build up courage.

At night, usually during the summer, a group of people visits an ominous place such as a cemetery, haunted house, or secluded forest path to carry out specific missions there. The exercise teaches the group that, working together, they can overcome their fear.
