Toyonaka Fudōson, Buddhist temple in Toyonaka, Japan.

Toyonaka Fudōson is a Shingon Buddhist temple on the upper slopes of Shimakuma-yama, a hill sung in the Man'yōshū. Its precinct holds a main hall for Fudō Myōō, a figure of Fudō Myōō that visitors pour water over, the small Shirayama Taishin shrine, and a Sanbō-den enshrining Amida, Shō Kannon and Shaka.

Toyonaka Fudōson was founded on 8 December 1962, when the Shugoson Kyōkai, a protective-deity association then in the Toyonaka city centre, moved to the top of Shimakuma-yama. The landowner of the hill absorbed the association and established it as a new temple, with its main image kept close to the hill itself. The temple belongs to the Shingon school (independent) and carries the mountain name Shion-zan.

The temple serves as a gathering place where local visitors come to offer prayers for personal wishes and seek spiritual guidance. The layout naturally encourages both quiet individual reflection and shared ritual practices throughout the year.

The temple stands on the upper slope of Shimakuma-yama in Midorigaoka 2-chome, Toyonaka. From Osaka Monorail's Shōji Station it is about a ten-minute walk; by bus, take Hankyū lines 45 or 49 from Senri-Chūō Station and get off at Toyonaka Fudōson-mae. By car it is just north of the Shimakuma-yama North and South intersections on the Osaka Central Loop Route.

Within the grounds stands Jōhakusan Daijin, described in the source as the only Shinto shrine inside a Buddhist temple compound. The temple also keeps a stele inscribed with the Man'yōshū poem on Shima-kumayama: "Tamakatsuma, in the dusk of Torikuma Mountain, will you cross the mountain path alone?"
