Tanjō-ji, Buddhist nunnery in Mitsumune-chō, Nara, Japan

Tanjō-ji is a Jōdo-shū nunnery in Mitsumune-chō, Nara, founded on the site of the residence of Fujiwara no Toyonari, father of Chūjō-hime. Its main hall enshrines a seated statue of the nun Chūjō-hōnyo, flanked by statues of Hōnen, Amida and the Twenty-Five Bodhisattvas. A garden mound holds the Gokuraku-dō with a stone statue of Chūjō-hime and stone images of the Twenty-Five Bodhisattvas descending to welcome her.

The site marks the birthplace of Chujo-hime, daughter of Minister Toyonari, who created the sacred Taima Mandala at Taimadera Temple during the Nara period. Its founding is closely tied to this important historical figure and her spiritual achievements.

The temple is also called Mitsumune-dono, after the three halls that once stood side by side on the grounds. The main hall enshrines a seated statue of the nun Chūjō Hōnyo, with her parents, Toyonari and Murasaki-no-mae, on the left altar. A wooden statue of Chūjō-hime is shown on 13 and 14 April each year.

The temple stands in Mitsumune-chō, Nara, and the Yakushi-dō sits outside the temple gate facing the approach path, so it can be seen before entering the grounds. The main hall, the hall on the raised garden mound and the Inari shrine inside the gate are all within the same small precinct. The wooden statue of Chūjō-hime and the Chūjō-hime Mandala are shown on 13 and 14 April each year.

The pond-side well in the grounds is called the Chūjō-hime ubuyu no ido, the well whose water is said to have been used for her first bath. Nearby in the garden, stone images of the Twenty-Five Bodhisattvas are arranged as if descending to welcome her, below a stone seated figure of the princess.
