Sensōji Kannon "Guide to Famous Spots of Edo Vol. 6".
(Japanese book)
Kinryūzan Sensōji Temple in Asakusa, Taitō Ward, enshrines a statue of the Bodhisattva Kannon (an important Buddhist deity) which is known affectionately as Sensōji Kannon. The roots of the story are said to date back to 628 when three fishermen fishing along the Miyato River (another name for the Sumida River) found the statue caught in their net on the morning of March 18. Although the temple was later left in a damaged state, it was reestablished by Shōkai Shōnin, a priest, in 645. When reestablishing the temple, Shōkai experienced a dream from which he decided that the image should be hidden from human view, and this meant that people were no longer able to pray to the deity directly.
