The Ietada Nikki records Kiyooki's fourth son, Shima Kiyomasa, within Yoshitsugu's ranks and he tried to kill Takatora in one blow. However, Kiyomasa was struck down and killed by an Eastern general named Takagi Heizaburō. Kiyomasa's fate echoed the situation of the Ōtani flanks as their defenses crippled from all sides due to the overwhelming numbers. Utterly defeated, Yoshitsugu lost his ground and is said to have committed suicide. Assuming that he was known as Yoshitaka, a grave marker was placed for him at Sekigahara.
