Chōsokabe clan
Chōsokabe clan, also known as Chōsokame, was a Japanese samurai kin group. Over time, they were known for serving the Hosokawa clan, then the Miyoshi clan and then the Ichijō clan.
Origin
The clan claims descent from the ancient immigrant clan called the Hata clan. The Hata clan, while originating from Korea; specifically from Paekche according to the Nihon Shoki, its lineage differs depending on the source. According to the Shinsen Shōjiroku, the Hata clan claims descent from Qin Shi Huang of the Qin dynasty. However, modern Japanese historians state that the clan most likely originated from the kingdom of Silla, another ancient kingdom of Korea. Hence making the Chōsokabe clan, a branch of the aforementioned Hata clan, also of Korean descent.However, in recent times, the self-proclamation of their Hata clan heritage is heavily scrutinized, with the general consensus within the Japanese academic circles labelling the clan's realistic origin as "Unknown".
History
The clan is associated with Tosa Province in modern-day Kōchi Prefecture on the island of Shikoku. Chōsokabe Motochika, who unified Shikoku, was the twenty-first daimyō of the clan.In their early history of the Sengoku period, Chōsokabe Kunichika's father Kanetsugu, was killed by the Motoyama clan in 1508. Therefore, Kunichika was raised by the aristocrat Ichijō Husaie of the Ichijō clan in Tosa Province. Later, towards the end of his life, Kunichika took revenge on the Motoyama clan and destroyed them with the help of the Ichijō in 1560. Kunichika would go on to have children, including his heir and the future Daimyo of the Chōsokabe, Motochika, who would go on to unify Shikoku.
First, the Ichijō family was overthrown by Motochika in 1574. Later, he gained control of the rest of Tosa due to his victories at the Battle of Watarigawa in 1575. He then also destroyed the Kono and the Soga clan. Over the ensuing decade, he extended his power to all of Shikoku in 1583. However, in 1585, Toyotomi Hideyoshi invaded that island with a force of 100,000 men, led by Ukita Hideie, Kobayakawa Takakage, Kikkawa Motonaga, Toyotomi Hidenaga, and Toyotomi Hidetsugu. Motochika surrendered, and forfeited Awa, Sanuki, and Iyo Provinces; Hideyoshi permitted him to retain Tosa.
Under Hideyoshi, Motochika and his son Chōsokabe Nobuchika participated in the invasion of neighboring Kyūshū, in which Nobuchika died. In 1590, Motochika led a naval fleet in the Siege of Odawara, and also fought in the Japanese invasions of Korea led by Toyotomi Hideyoshi in 1592.
After Motochika died in 1599 at age 61, the next clan leader was his son Chōsokabe Morichika. He led the clan forces in support of the Toyotomi at the Battle of Sekigahara. After 1600, the Chōsokabe were removed as daimyo of Tosa.
After the Siege of Osaka in 1615, Morichika was executed and the clan was ended as a political and military force.
Among the retainers to the clan were Kōsokabe Chikayasu, Tani Tadasumi, Hisatake Chikanao, Yoshida Takayori, Yoshida Shigetoshi, Yoshida Masashige.
Shirō Sōkabe, the 19th century missionary, was a descendant of the Chōsokabe clan.
