Kagawa clan

Kagawa clan a rather minor Japanese clan during the Sengoku period (16th century) of Japan. Throughout the course of the Sengoku period, the Kagawa family had very strong bonds with the powerful clan of Chosokabe, in which they had at many times received members from the Chosokabe family as used for adoptive survival. After the Chosokabe clan went relatively extinct due to their rebellions against the Tokugawa Shogunate during the Edo period (17th century), the Kagawa clan died out.
