The Nagatoro Funadama Festival held annually on the Arakawa River in the Chichibu area of Japan in Saitama prefecture is but one example among many, of ancient river or water expulsion practices still practised today in Japan. The Nagatoro Fireworks festival is held right beside the river, preceded by sending off a boat lit up with lights. The festival takes place during the Bon period, to honor the spirits of the dead that visit the realm of the living during this period. After dark, boats decorated with paper lanterns and about 1,000 individual lanterns are floated on the waters of the Arakawa River to pray for the repose of drowned persons, creating an otherworldly atmosphere.

In folklore, there is a famous River of the Dead called Sai-no-kawara, for which there are actual varying physical locations in Japan, the most famous one being perhaps Kusatsu’s Sainokawara Park. And according to tradition, here it is Jizo is the most beloved and well-known of folk deities, who is the guide for the lost souls of children on the Sai-no-kawara riverbank, and who saves them from either the Oni (ogre demon) or Shozuka-no-baba (see photo of her enshrined) who is the hell’s hag receiving the souls of the dead, and wife of Ten Datsu-Ba (source: Mythology Dictionary). She demands money from all who arrive at her home on the bank of the River of Three Roads (River Sanzu) and, if it is not paid, takes their garments…one version of the story is found in the folktale “Broken Images“:
“I am Jizo, who guards the souls of little children. It is most pitiful to hear their crying when they come to the sandy river-bed, the Sai-no-kawara. O dreamer, they come alone, as needs they must, wailing and wandering, stretching out their pretty hands. They have a task, which is to pile stones for a tower of prayer. But in the night come the Oni to throw down the towers and to scatter all the stones. So the children are made afraid, and their labour is lost.”

Pottery with faces painted in black ink have been excavated from the Mizutare archaeological site of Nagaoka Palace in Kyoto Prefecture.
Archaeologists have also found fragments of earthenware jars that had been tossed into a dried-up riverbed of a tributary of the Yamatogawa River (in today’s Yao city, Osaka) in a ritual to bring salvation and ward off illness. Distinctive faces had been painted in black ink on the small pottery jars. Along with the pottery jars, seven types of coins were discovered, along with Kocho-Junisen copper coins from the Nara (710-784) period (as well as Kangen-Taiho coins minted in the 958 which suggests the practice continued through the early Heian (794-1185) period).
Crossing the river at the time of death, as part of the journey to another world, is a common part of the symbolic passage that people have seen as part of one’s journey after death. In the Epic of Gilgamesh, the hero encounters a boatman who ferries him across the waters of death as he seeks the secret of immortality. The river Styx of Greek mythology is well known as the chief river of Hades, said to flow nine times around its borders. Styx is married to the Titan Pallas and according to Hesiod counts as her children Rivalry, Victory, Power, and Force. The power of the Styx is evidenced in the fact that Achilles gained his invulnerability by being dipped in the river as a baby held by his heel, the only part of his body thereafter vulnerable to mortal wounds. In addition, the most inviolable oath of the gods is sworn with a jug of water from the Styx, poured out while the oath is being uttered.
In Hindu mythology, the river Vaitaran: marks the boundary between the living and the dead; in the Aztec journey, the river Mictlan must be crossed on the way to the underworld; in Japan, rivers are part of certain landscapes designated as realms of the dead in both the Shinto¯ and Buddhist traditions. The Sanzunokawa, for example, is said to divide the realms of the living and the dead. The dry riverbed of Sainokawara is said to be the destination of dead children.
The far shore of the river of life and death, or birth and death, thus becomes an important symbol for the destination of one’s spiritual journey in many religious traditions. In the Buddhist tradition, nirva¯n: a is referred to as the “far shore.” In the Hindu tradition, holy places are called t¯ırthas (“fords”) because they enable one to make that crossing safely. Riverbank t¯ırthas, such as Banaras and Prayaga, are thought to be especially good places to die. In the Christian tradition, crossing over the Jordan has come to have a similar symbolism. On the far shore is not only the promised land, but the spiritual promised land of heaven. Home is on the far shore…”
