Emperor Tsuchimikado (1196-1231) did not participate in his father Go-Toba's 1221 uprising and was exempted from punishment by the Kamakura shogunate. But out of family solidarity, he voluntarily requested exile and was sent to Tosa, then Awa province. He died there at age 35. Ironically, his son later became Emperor Go-Saga, restoring his line to imperial succession.

Tosa (modern Kochi) and Awa (modern Tokushima) in southern Shikoku served as Nankaido exile sites in classical Japan. [Emperor Tsuchimikado](/character/sanetomo) (1221, who voluntarily requested exile) and Minamoto Mareyoshi (1160, Yoritomo's younger brother) are the most prominent figures sent here. The legacy of these exiles intertwines with the later Shikoku 88 Pilgrimage culture in unique ways.
