It is not known when the Tosa Shrine was founded. Per the shrine's legend (as recounted in the late Kamakura period Shaku Nihongi) when Emperor Yuryaku was hunting near Mount Yamato Katsuragi in Yamato Province, he encountered Hitokoto-no-nushi no kami, but due to his irreverent behavior the Emperor had him exiled to Tosa Province. The exiled deity was first enshrined at a place called 'Kamonochi' where the locals worshipped a god called "Kano Omikami" and was later transferred to the present location. There are various candidates vying for the location of this first shrine, including the Kano Jinja in the town of Kuroshio, Kano Jinja in Susaki and Narunashi Jinja in Susaki. The exact location of the Tosa Kokufu is also uncertain; however, the area around the shrine has many late Kofun period (6th century to 7th century) burial mounds and per the "Tosa no Kuni Fudoki", there was a government administrative complex located some two kilometers east of the Tosa Shrine.
The first historical record of Tosa Shrine is found in "Nihon Shoki" in an entry dated to the 4th year of Emperor Tenmu (675), which details the submission of the local Tsuchisa no Ōkami Hosai clan to the Imperial Court. In addition, an entry of August in 686 mentions the dispatch of offerings from the Imperial Court to Tsuchiza no Ōkami following the Hakuho Earthquake of 684, and response to Emperor Tenmu's deteriorating physical condition from June 686. In the "Shinsho Kakuchokufusho" of 765, 20 of the 53 shrines added to 'Takakamo no kami' were found in Tosa Province, suggesting a relationship with the Kamo clan in Kyoto. The Tosa Shrine was promoted to the highest rank in 940 AD due to successful prayers for the suppression of the Fujiwara no Sumitomo rebellion.
In the Engishiki records, the shrine was named as a Myōjin-taisha, the only such shrine in Tosa Province. Per the "Hyakurensho" records of 1224, the shrine was completely destroyed by a typhoon. The shrine is first named as the ichinomiya of they province in 1326 in an account of a battle between forces of the Northern and Southern Courts which occurred in the vicinity. It is believed that a shōen manor called Ichinomiya-shō was formed around the shrine during the Kamakura period, and that the priests of the shrine became secularized samurai in the Muromachi period under the name of the "Ichinomiya clan". The shrine was destroyed again around 1509 in the wars of the early Sengoku period,and was reconstructed by Chōsokabe Motochika, with the current Honden, Heiden and Haiden of the shrine completed in 1571. Various vassals of the Chōsokabe were assigned to reconstruct lesser structures and several villages in the vicinity of the shrine were assigned to the shrine for its upkeep. During the Edo Period, the Yamauchi clan who ruled as daimyō of Tosa Domain, further constructed to the shrine, with the second daimyō, Yamauchi Tadayoshi, contributing the Rōmon tower gate in 1631 and a drum tower in 1649.
Following the Meiji restoration, the shrine was renamed Tosa Jinja in 1871 and it was designated a under the Modern system of ranked Shinto shrines. After World War II, it was redesignated a Beppyo Shrine under the Jinja Honchō. In 2003, an archaeological excavation on the west side of the precincts found the foundations of the medieval mansion and other structures related to temples and shrines.
