Hojo Soun (1432?-1519, born Ise Moritoki) opened the Sengoku era. Once portrayed as a ronin who rose by force, modern scholarship reveals him as a Muromachi shogunate official from the prestigious Ise clan. He conquered Izu in 1491 by overthrowing Ashikaga Chachamaru, captured Odawara Castle in 1495, and founded the Later Hojo dynasty. His “four-six” tax policy (40% to lord, 60% to farmers) and the ethical code Soun-ji-dono Nijuichi-kajo preserved his reputation as a sophisticated statesman who introduced new governance to eastern Japan.
