Chōsokabe Motochika

A Shikoku warlord

Chōsokabe Motochika (1539–1599) was a daimyō, a territorial lord of the Japanese civil war period known as Sengoku. Hailing from a family established at Okō Castle in present-day Kōchi Prefecture, he took leadership of the clan after his father's death in 1560. He unified Tosa Province in 1575, then extended his authority over a large part of Shikoku.

This expansion reached its peak in 1585. That same year, Toyotomi Hideyoshi's military intervention forced his submission: Motochika retained Tosa, but had to surrender his other conquests. His legacy was not limited to military campaigns; he also organized the government of his territory through land surveys and legal codes.

Why does his name appear on temple pages?

The wars of this era affected several shrines and temples of the pilgrimage. In their historical records, certain destructions are linked to Motochika's campaigns. For instance, the 88 Temple Pilgrimage Association records that Ido-ji, temple 17, suffered from fighting between Miyoshi Yasunaga and Chōsokabe Motochika in 1582.

Each case must be examined individually, however: a temple damaged during a campaign was not necessarily burned down by his personal order. A traditional attribution passed down by a temple should be presented as such, without automatically attributing every destruction in Shikoku to him.

A historical figure tied to Kōchi

His tomb is located in Nagahama in the city of Kōchi; it is designated a historic site by the prefecture. It serves as a reminder of his significance in the history of Tosa, beyond the wartime episodes recalled along the temple trail.
