Marubashi Chūya

Marubashi Chūya was a rōnin from Yamagata, and instructor in martial arts and military strategy, most famous for his involvement in the 1651 Keian Uprising which sought to overthrow Japan's Tokugawa shogunate. He is said to have been a man of great strength and good birth whose distaste for the shogunate stemmed primarily from a desire for revenge for the death of his father, killed by the shogunal army at the 1615 siege of Osaka. The identity of his father is not clear, but may have been Chōsokabe Motochika.
