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. Kaidan have been standard in kabuki and rakugo from long ago. In the summer there are events all around Japan, such as gathering 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?
