玉諸神社, Shinto shrine in Japan

Tamamoro-jinja is a Shinto shrine in Kugama-cho, Kofu, Yamanashi Prefecture, counted among the candidates for the Engishiki-listed shrine of Yamanashi District, Kai Province, and ranked as the province's third shrine (sannomiya). Its grounds hold a worship hall and several subsidiary shrines, and about 1.5 km north, near the Maedzuka mound, lies the site of its former worship hall, a vantage point for venerating Mount Mimuro.

According to shrine tradition, the deity was first worshipped on Mount Mimuro north of Sakaori, and Yamato Takeru later buried a jewel here to stop floods, planting a cedar as its dwelling; the shrine took its name from that "Tama-muro" cedar. The surrounding place name Kudama derives from the shrine. It was destroyed by fire in 1582 when the Takeda clan fell, then protected by the Tokugawa, who confirmed 61 koku of revenue in the Edo period.

The shrine is Kahi Province's third-ranked shrine (sannomiya). In the spring Goyō Festival, its deity is carried with those of the first and second shrines to the Sansha Shrine near Shingen-tsutsumi for a river-protection rite; today only the Ryūō Sansha Shrine is visited. A horse called "Bomboko-san", bearing a bonten on its saddle, appears in the festival, as shown in a 1759 painting.

The grounds are easily accessible on foot, approximately 18 minutes walking distance from Sakaori Station. Visitors can explore the peaceful paths and best enjoy the surroundings during cherry blossom season in spring.

The shrine's spring Miu-kyō festival links it with Ichinomiya and Ninomiya shrines in a kawayoke-sai, a riverbank ritual against flooding. A horse called "Bomboko-san" is carried out, a saddle topped with a bonten pole, already depicted in the 1759 Miu-kyō festival picture scroll by Miyake Narumi.
