In Japanese folklore there are both toilet gods and toilet demons. The toilet gods are household deities, the toilet demons are water demons. Let’s look at the gods first, then the demons.
Toilet Gods
There is only very limited livestock on Japan farms. Human waste has traditionally been collected in cesspits and used as fertilizer. This meant that there was a risk of falling into a cesspit and possibly drowning. Protection was needed against this dreadful fate. Also, since the collected waste was used for fertilizer, the toilet was connected with fertility in general.
The kawaya no-kami or toilet god was asked for help. Special rituals at the new year asked for the kawaya no-kami to bring a good harvest. Keeping the toilet clean was thought to lead to more attractive children.
The specific name and rituals associated with the toilet god vary with location. The name is Takagamisama around Nagano, Setchinsan in Hiroshima, Kamu-taka on Ishigaki Island, Sechinbisan in Ōita, and Usshimasama in Ehime. In some places the family sit in front of the toilet on a straw mat and eat a rice cake, in other places they would put an offering of food into the toilet.
In far northern Japan the Ainu people believed that their toilet god, the Rukar Kamuy, would be the first deity to provide help in times of danger. The Rukar Kamuy is one of many Kamuy or household gods. There is Apasamn Kamuy the husband and wife god and goddess who keep evil spirits out of the house entrance. Cisepannokianpa Kamuy and Cisepennokianpa Kamuy, the husband and wife god and goddess of the eaves of the roof, protect the house from earthquakes and typhoons. Cisekor Kamuy, a male god, sits in the east corner of the house and watches over everything. He is the husband of Apehuci Kamuy, the goddess of fire. Colpep Kamuy is the god of containers, thanks are given to this god when containers are retired.
