Hyakumonogatari Kaidankai was a popular didactic Buddhist-inspired parlour game during the Edo period in Japan.

Yūrei are figures in Japanese folklore analogous to the Western concept of ghosts. The name consists of two kanji, 幽 (yū), meaning "faint" or "dim" and 霊 (rei), meaning "soul" or "spirit". Alternative names include Bōrei (亡霊), meaning ruined or departed spirit, Shiryō (死霊), meaning dead spirit, or the more encompassing Yōkai (妖怪) or Obake (お化け). Like their Chinese, Korean, and Western counterparts, they are thought to be spirits barred from a peaceful afterlife.
