Kokkuri-san is the most famous scary game in Japan. It is similar to the Ouija board and is mostly played by Japanese schoolchildren who want to summon a spirit so they can ask questions about the future. Kokkuri-san is Japan's answer to the Ouija board and it has been played in schoolrooms across the country for years. The game became so widespread in Japan that it sparked several hysterias in the media and many schools officially banned students from playing Kokkuri-san. To play Kokkuri-san, you need at least two people, a sheet of paper, a pen and a coin.
