In the context of esoteric Buddhism (Japanese: 密教, romanized: Mikkyō), the name of the temple refers to the saint of water, Jinja Daiō (深沙大王).
According to the temple tradition, the daughter of Sato Osaukon (郷長右近) fell in love with a man named Fukuman (福満) in the area.
After passing the gate, the temple bell (Japanese: 鐘楼, romanized: Shōrō, map: 4) can be seen on the right, and ahead the main hall (Japanese: 本堂, romanized: Hondō; map: 2).
[1] To the left of the main hall, and set back, is the 'Gansandaishidō' (元三大師堂; map: 3), which was popular in the Edo period, for praying for good fortune in life.
In 1900, a group of sculptures of a seated Shaka Buddha with two companions made of bronze with gold traces (Japanese: 金銅釈迦如来椅像, romanized: Kongō Shaka Nyorai Izō) was discovered underneath the hall, for which a separate building, the Shakadō (釈迦堂; map: 5) was built.
