After the death of Toyotomi Hideyoshi, the power of the Toyotomi clan declined and Japan would go to war again. In 1600 in the Battle of Sekigahara, the Tachibana clan would ally itself with Ishida Mitsunari in the Western army against the Eastern Army of Tokugawa Ieyasu. Ginchiyo first opposed Muneshige's decision to join the Western army.
