Wakamiya Hachiman-gū, A shrine in Kochi City, Kochi Prefecture.

Wakamiya Hachiman-gū is a Shinto shrine in the city of Kōchi featuring traditional wooden buildings and a stone path leading to the main hall. The grounds include several smaller shrines dedicated to other deities, including one for Ebisu, god of fishing and commerce, as well as spaces for prayers regarding safety and prosperity.

According to the Kamakura-period chronicle Azuma Kagami, Minamoto no Yoritomo founded Rokujō Wakamiya Hachiman-gū in Kyoto in 1185 and had a branch of it established here on the 30th day of the 12th month of that year, with Agawa District in Tosa Province made shrine land. In 1560 Chōsokabe Motochika camped before the shrine on his first campaign and won; thereafter he prayed here before every battle. Under the Yamauchi lords of Tosa it was one of eight shrines of domain prayer, became a village shrine in 1873 and a prefectural shrine in 1930.

The shrine's name comes from its founding as a branch of Kyoto's Rokujō Wakamiya Hachiman-gū in 1185. Its April Kanda Festival, called the Doronko Matsuri, has about 300 men and women in yukata offering rice and seedlings; twelve saotome then plant the sacred paddy and smear mud on men's faces and limbs, said to ward off illness for the summer. The November 6 procession, the Onabare, includes a tengu-masked Sarutahiko and ten boys in white makeup and women's dress carrying wooden naginata.

The shrine stands at 6600 Nagahama, Kōchi, about five minutes on foot south of the Minami Naka School bus stop on the Tosa Den Kōtsū Katsurahama line. The outer garden holds the bronze statue of Chōsokabe Motochika, about 7 m tall with a 6 m spear, facing a map of Shikoku.

The torii gate has been rebuilt several times: after a 1865 earthquake exposed its foundations, a wooden gate was erected in 1870, replaced in 1936, and rebuilt in reinforced concrete in 1980. According to tradition, Chōsokabe Motochika once had an earlier gate dismantled and thrown into the sea after a bad omen.
