Kaidan is a feature of Japan's summer. Japanese people enjoy scary stories as a form of entertainment, which is a sense that is different from foreigners. In the summer, there are events all around Japan, such as gatherings to tell each other Kaidan and Kaidan tours. Unique sounds that express scariness, such as "hyudoro" with flutes and drums, are also different from overseas. Are Japanese people who enjoy Kaidan in the summer as a form of entertainment cool?
