Tanema-ji, Buddhist temple of the Shikoku Pilgrimage in Kōchi, Japan

Tanema-ji is a Shingon temple of the Buzan school on a hillside in Kōchi, entered through a stone-pillar gate. A bell tower stands just inside; to its right are the water-child Jizō hall, the Kannon hall with a cast Koyasu Kannon surrounded by ladles with holes in their handles, and a small Ishizuchi shrine. The abbot's quarters and stamp office lie to the right, the Daishi hall beyond, and a concrete main hall at the rear. The grounds hold a miniature 88-temple circuit of boat-shaped stone Buddhas.

According to temple records, a Baekje carpenter who had come to build Shitennō-ji was blown ashore near here around 585–587 and carved a Yakushi Nyorai at the hilltop. In the Kōnin era (810–824) Kūkai built the hall, enshrined that image, and sowed five grains brought from China, giving the temple its name. Emperor Murakami granted a "Tanema" plaque in the Tenryaku era (947–957). Abolished in 1871 under the separation of Shinto and Buddhism, it was restored on the present site in 1880.

Tanema-ji is the 34th of the 88 stations of the Shikoku Pilgrimage, and pilgrims receive their red seal (nōkyō) here for the main image and the Okunoin. The temple is known for safe childbirth, and a cast Koyasu Kannon in the Kannon hall is surrounded by ladles with their bottoms removed, left as offerings. The grounds also hold a miniature 88-site circuit of boat-shaped stone Buddhas.

The grounds are accessible via marked pathways with good signage for visitors to navigate. Comfortable footwear is recommended since the paths cross hillsides and the terrain can be uneven.

The temple name comes from the five grains Kukai is said to have sown on the grounds after bringing them from China. The main hall's seated Yakushi Nyorai, a lacquered wood figure 140.3 cm tall from the late Heian period, is opened to view each year on 8 March and is a nationally designated Important Cultural Property.
