Nyakutakuji, Former Buddhist temple in Matsumoto, Japan

Nyakutakuji was a Shingon temple on the slope of Mount Mizusawa in Hata, Matsumoto, at about 940 m elevation. Its grounds were terraced in several levels, each once holding buildings such as the kuri, the Chudo Kyuseiden, the Kondo and the Tamurado. Stone foundations of these structures remain among the trees, and the site covers about 11,000 square metres.

Tradition holds that Gyoki founded Nyakutakuji on the slopes of Mount Mizusawa during the Tenpyo-shoho era (749-758), near the summit at a spot later called Mototeraba. In the Daido era (806-809) Sakanoue no Tamuramaro is said to have had it rebuilt during his eastern campaign. In the Edo period successive shoguns confirmed a temple estate of 10 koku, and after a rebuilding around 1804 it was called Shinano Nikko. It was abolished in September 1871 under the anti-Buddhist policy of Matsumoto domain.

The temple's main image was kept in a miniature shrine later called Tamura-dō, moved after the temple's abolition to the Kami-Hata settlement and now protected by a shelter; it has been a National Important Cultural Property since August 1953. Many of the temple's Buddhist statues were transferred to Shōsen-ji in Naka-Hata, where several remain enshrined.

From the plaza at the foot of the hill, the Niomon gate stands to the west, with the Tamura-do about 30 meters beyond it. The mountain trail to the temple site begins about 100 meters up the road on the south side of the plaza; from the left turn, the path climbs roughly 1,900 meters. The Niomon passage is always open, but the statues cannot be touched.

The Niō gate that served as Nyakutakuji's mountain gate still stands in the settlement below, and its two wooden Kongōrikishi statues date to 1322, carved by the sculptor Myōkai of Zenkōji for the temple's branch temple Saikōji. Locals call them "Niō-sama"; the left figure is Agyō and the right Ungyō. Each April, children are passed between Agyō's legs in a rite said to ease measles.
