Sekisui-ji Temple is said to have been founded by the high priest Gyoki during the Nara Period (710–794). Its name “Sekisui-ji” used to be written using the characters for “stone” and “water,” because there was water springing from a massive rock on the grounds of the temple, but it came to be written using the characters for “accumulation” and “green” after the Middle Ages.
According to legend, Takeda Nobutora’s wife fled to this temple to escape the ravages of war, and here gave birth to Takeda Shingen in 1521. The well from which water was drawn for Shingen’s first bath and a small shrine dedicated to the bathwater god still exist in the temple precincts, and the Fudo-do Hall on the left side of the main hall enshrines images of the fire god Fudoson and Takeda Shingen. Historical records note that Shingen held poetry gatherings at this temple in later years.
