Chikubujima-ryū Bōjutsu

In this Bōjutsu school, the Kiai are at least as important as the techniques themselves. The exercises can be interpreted as a type of Misogi.

The founder of this school is Heiji Mitsunori of Namba, who worshipped the goddess Benzaiten on the island of Chikubushima in Lake Biwa. He had a vision that he attributed to the goddess.
Nanba Heiji Mitsunori (難波平治光閑) was an excellent long sword wielder. He took part in the Genpei War (around 1184). However, his sword broke in battle. With the stick he had still, he was able to defeat a large number of opponents.

Benzaiten

also called Benten or Benzai-tennyo (弁財天女, literally: "heavenly goddess of eloquence"), is a Japanese protective deity who is also worshipped in Shinto and is one of the Seven Gods of Fortune (Shichi Fukujin). She has her origins in the Indian river goddess Sarasvati, who is worshipped in both Buddhism and Hinduism.
A Benzaiten legend describes how she tamed a dragon that had devoured many children by becoming its wife. In gratitude, the Enoshima Shrine was built for her. In other Benten shrines, however, the goddess is also described as very jealous. Therefore, men and women should not visit these shrines together.
Like Sarasvati, Benzaiten is associated with eloquence, music, art and wisdom. She is also considered the protector of geishas, dancers and musicians, and sometimes helps people to gain wealth. She is particularly connected with water. Therefore, most of her shrines are on small islands in lakes, ponds or the sea.
