Shingen designated Erinji as the Takeda clan's family temple during his lifetime and was buried here by his own wish after his death in 1573. His mausoleum remains on the grounds and draws devoted visitors to this day. The burning of the temple during Nobunaga's 1582 invasion of Kai—when the abbot Kaisen died in the flames reciting his famous verse—was a direct result of the temple's intimate ties to the Takeda.
