The Narita-san ("Narita mountain") Shinshō-ji ("New victory temple"), a Shingon Buddhist temple located in central Narita, Chiba, Japan, is established in 940 to commemorate the victory of the forces dispatched from the Heian capital to suppress the revolt by the powerful Kantō region samurai, Taira no Masakado.
The Shingon priest Kanchō had accompanied the force, bringing with him an image of Fudō myōō from the Gomadō (Fire Offering Hall) of Takao-san Jingo-ji in Kyōtō.
Shingon founder Kōbō Daishi himself is said to have carved the image and used it in Goma sacred fire rituals that helped stop a rebellion during his era.
The rebellion in 940 also comes to an end just as Kanchō completes a three-week Goma ritual with the same image.
