Battle of Komaki and Nagakute
During the Battle of Komaki and Nagakute, Shigeoki aided Tokugawa Ieyasu and surrendered to Toyotomi Hideyoshi's vast army after the battle's conclusion. Though he swore to serve Hideyoshi, Tōdō Takatora suspected that keeping a formidable enemy within their ranks was too risky to trust. Therefore, Shigeoki was sentenced to commit suicide. He died when he was 75. His four sons survived him. Their names were Shigekane, Shigehide, Yoshikane, and Shigetomo.
