The origins of Toga Shrine are unknown. The shrine claims to have been founded in the
Taihō period (701-704 AD) by
Emperor Mommu. It is located in an area of eastern Mikawa with a favorable climate, which has been settled since at least the
Jōmon period. One of the treasures of the shrine is a
Yayoi period dōtaku bronze ritual object, possibly recovered from a
burial mound in the area. The shrine first appears in historical documentation in the early
Heian period Nihon Montoku Tennō Jitsuroku in an entry dated 850 and subsequently in the
Nihon Sandai Jitsuroku in an entry dated 864. The shrine is mentioned as the
ichinomiya of Mikawa Province in the 927
Engishiki records. During the
Sengoku period, it was battleground between the forces of
Tokugawa Ieyasu and the
imagawa clan. It was given a small stipend of 100
koku by the
Edo period Tokugawa shogunate. With the establishment of
State Shinto after the
Meiji restoration, the Toga Shrine was designated as a {{nihongo|National Shrine, 3rd rank|国幣小社}|
Kokuhei Shōsha}}. in the
modern system of ranked Shinto Shrines. The shrine is a five-minute walk from
Mikawa-Ichinomiya Station on the
