洞雲寺, Buddhist temple in Tokoname, Japan.

Touun-ji is a Buddhist temple in Tokoname featuring a main hall with traditional architectural designs and a central altar that houses a Buddha statue. The building displays classic elements of Japanese worship spaces with careful attention to structural proportions and interior arrangement.

Founded on 8 April 1555 by the monk Zenkai, the temple belongs to the Seizan Jōdo-shū school. Its main image, a seated Amida Buddha, was found when a pond was dredged; it had been buried, along with other statues from the burned Kōsan-ji, to save them from the fighting between the Oda and Imagawa. In 1809 Ryōzan founded the Chita Shikoku pilgrimage and Tōun-ji became its 62nd stop.

Tōun-ji belongs to the Seizan Jōdo-shū school and is the 62nd stop on the Chita Shikoku pilgrimage, the 13th on the Chita Saigoku thirty-three-site route and the 12th of the Hōnen Shōnin Chita twenty-five sites. It is known for the "Munen Nade Daishi", a statue visitors rub to transfer wishes, and as a lotus temple; in 2010 a cat-shaped "Neko Daishi" by Ozawa Yasumaro was dedicated here.

Visitors can walk through the temple grounds during regular opening hours and should inquire beforehand about available tour options. The location is easy to reach on foot and provides ample space for leisurely exploration.

In 2010 the temple received a cat-shaped statue called Neko Daishi, made by Ozawa Yasumaro, and that same year a rare double-headed lotus bloomed in its pond. The temple is also known for a "mune-nade Daishi" statue that visitors rub for good health.
