According to popular theory In 1598 after the death of Toyotomi Hideyoshi, the government of Japan had an accident when seven military generals consisted of
Fukushima Masanori,
Katō Kiyomasa,
Ikeda Terumasa,
Hosokawa Tadaoki, Asano Yoshinaga,
Katō Yoshiaki,
Kuroda Nagamasa,
Hachisuka Iemasa,
Tōdō Takatora, and
Kuroda Yoshitaka brought their troops and entourage to storm Ishida's residence to
confront Mitsunari. When they found out that Mitsunari was not in the mansion, they searched the mansions of various feudal lords in Osaka Castle, and Kato's army also approached the Satake residence. Therefore, Mitsunari and his party escaped from the Satake residence and barricaded themselves at the
Fushimi Castle. The next day, the seven generals surrounded Fushimi Castle with their soldiers as they knew Mitsunari was hiding there.
Tokugawa Ieyasu, who was in charge of political affairs in Fushimi Castle tried to arbitrate the situation. The seven generals requested Ieyasu to hand over Mitsunari, which was refused by Ieyasu. Ieyasu then negotiated to let Mitsunari retire and to review the assessment of the Battle of Ulsan Castle in Korea which became the major source of this incident. He later told his second son,
Yūki Hideyasu, to escort Mitsunari to Sawayama Castle. However, historian
Watanabe Daimon stated from the primary and secondary sources about the accident that this was more of legal conflict between those generals rather than conspiracy to murder him. The role of Ieyasu here was not to physically protect Mitsunari, but to mediate the complaints of those generals. Nevertheless, historians viewed this incident not just simply personal problems between those seven generals and Mitsunari, but rather as an extension of the political rivalries between the Tokugawa faction and the anti-Tokugawa faction led by Mitsunari. Since this incident, military figures who didn't like Mitsunari would later support Ieyasu during the conflict of Sekigahara between the Eastern army led by Tokugawa Ieyasu and the Western army led by Ishida Mitsunari. Muramatsu Shunkichi, writer of "
The Surprising Colors and Desires of the Heroes of Japanese History and violent women”, gave his assessment that the reason of Mitsunari failure in his war against Ieyasu was due to his unpopularity among the major political figures of that time. Though the Asano clan was secure following its service under
Tokugawa Ieyasu at the
Battle of Sekigahara, it would be moved to
Wakayama Domain, in
Kii Province. The clan would again be moved, to
Hiroshima Domain, in the early 17th century. ==Personal life==
