Jingū-ji, Buddhist temple in Taki, Japan.

Jingū-ji is a Shingon Buddhist temple of the Yamashina school in Taki, Mie Prefecture, on Mount Nyū. Its full name is Nyonyo Kōyasan Nyūsan Jingū-ji Jōju-in, and it is commonly called Nyū Daishi after Kūkai. The grounds contain a Niō gate, main hall, Daishi hall, goma hall and guest hall, all designated town tangible cultural properties.

Founded in 774 by the monk Kinsō under Emperor Kōnin's decree, the temple is linked to Kūkai, who returned from Tang China in 810 and chose Niu for his esoteric Buddhist centre. A legend says his three-pronged vajra landed first at Niu before bouncing to Kōyasan. In 813 Kūkai had the halls built.

The temple is the jingū-ji of the adjacent Niu Shrine, and its common name Niu Daishi refers to Kūkai (Kōbō Daishi). Unlike Kōyasan, which barred women, this temple admitted female worshippers, earning it the name Nyonin Kōya. Monthly rites are held on the 21st, with major ceremonies in April and October.

The temple is accessible by local bus from Taki station, with parking available for those driving independently. Visitors should plan for unhurried movement through the grounds and wear appropriate footwear to navigate the landscaped areas comfortably.

The temple is commonly called Nyū Daishi, after Kūkai (Kōbō Daishi), who is said to have repaired its halls in 813. Legend holds that he threw a three-pronged vajra from Tang China toward Japan; it first landed at Nyū but bounced to Mount Kōya, which became the Shingon headquarters instead.
