Wakayama-jinja, Shinto shrine in Japan

Wakayama-jinja is a Shinto shrine in Shimamoto, Osaka Prefecture, dedicated to Susanoo-no-Mikoto. Its main hall, built in 1807 in the three-bay nagare-zukuri style, has a wide central bay and a projecting karahafu gable over the entrance. The shrine grounds contain a grove of about 200-year-old Castanopsis sieboldii trees, and views extend to Mount Otokoyama and the confluence of the Katsura, Uji and Kizu rivers.

According to shrine tradition, the monk Gyōki founded it in 701 on the orders of Emperor Monmu, enshrining Susanoo-no-Mikoto. In 1074 it was ranked among the official shrines, and the temple Shōbatsu-ji served it as a jingū-ji. Emperor Go-Toba sent an imperial envoy, and Kusunoki Masashige had a senior retainer worship here when he parted from his son Masatsura at Sakurai. Renamed Wakayama-jinja in the Meiji era after the local place name, it was formerly called Nishi-Hachioji-sha or Gozu-Tennō-sha.

The shrine was long called Nishi-Hachioji-sha or Gozu Tenno-sha; the name Wakayama-jinja was adopted in the Meiji era under the separation of Shinto and Buddhism, taken from the local place name. Its festival dance, the Okage-odori held in 1831 by the Wakarenju of Todai-ji village, is recorded on a large votive plaque, 90 by 121 cm, donated by eight local men.

The nearest station is Hankyu Kyoto Line Minase Station; from there take a Hankyu bus to the Wakayamadai Center stop, then walk about 9 minutes (roughly 700 m) northwest. The shrine grounds include the wooded precinct and the subordinate Kogarasu and Momoyama Inari shrines.

The shrine's grove is a stand of Castanopsis cuspidata trees around 200 years old, designated an Osaka Prefecture Natural Monument on 29 January 2002 and listed among Osaka's 100 Green Selections. From the grounds visitors can see Mount Otokoyama and the confluence of the Katsura, Uji and Kizu rivers.
