Kagawa clan

The clan died out after the Chōsokabe fatally rebelled against the Tokugawa Shogunate in the early 17th century.

On March 3, 1222, Yoshikage moved from Sagami Province to Aki Province with his older brother Tsunetaka's eldest son, Kagawa Kagemitsu, and built a mountain castle (Yagi Castle) at the foot of Yagiyama, jutting out into the Taiga River.

His second son, Kagetsugu, went to Kyoto in 1673, took the name Nobuaki, revised and expanded the Intokuki, and published it as the Intoku Taiheiki.

Nobuaki abandoned his samurai life and lived in Kyoto as a poet, serving the Tokudaiji family under the pseudonym "Baigetsudo."

His descendants also served the Tokudaiji family for generations, producing many famous poets until the Meiji Restoration.
