Sanzu River
The Sanzu-no-Kawa (三途の川; "Sanzu River", literally the "Three-World River" in reference to Buddhist ideas about realms of existence) is a mythological river in Japanese Buddhist tradition similar to the Chinese concept of Huang Quan (Yellow Springs), Indian concept of the Vaitarani and Greek concept of the Styx. Before reaching the afterlife, the souls of the deceased must cross the river by one of three crossing points: a bridge, a ford, or a stretch of deep, snake-infested waters.
