Japanese: 木沢長政 - きざわ・ながまさ

Year of death: 17 March 1542 (2 April 1542)
Year of birth: Unknown. A military commander during the Warring States period, he was deputy governor of the Hatakeyama clan, the governor of Kawachi (Osaka Prefecture). Later, he served under Hosokawa Takakuni and Hosokawa Harumoto and participated in the wars in the Kinai region. From 1530 (Kyoroku 3), he followed Harumoto and defended Kyoto. In February of the following year, he fought against Naito Hikoshichi and others on Takakuni's side and defeated them. In July of the same year, he defeated Hosokawa Tadanobu, who was on Takakuni's side, in Tomida, Settsu, and became the lord of Imori Castle (Shijonawate City) due to his achievements. In 1532 (Tenbun 1), his former lord, Hatakeyama Yoshitaka, was outraged and attacked Imori Castle, but Nagamasa asked Harumoto for help, and Harumoto asked Honganji Shonyo to support Nagamasa, so Yoshitaka committed suicide at the Kawachi Ishikawa dojo following an attack by the Ikko Ikki. In the following year, together with Harumoto, he attacked Hongan-ji Temple with the help of the Hokke Ikki, and eventually made peace with Shonyo, but continued to be at odds with the Ikko Ikki, and in the following year, he defeated the Ikki at Nakajima in Settsu. He supported Yoshitaka's younger brother Ariuji at Imori Castle, and then built Shigisan Castle in Yamato Province, expanding his influence. In July of the 9th year, he disowned his father Ukiyo, and in August of the 10th year, he conspired with Yusa Naganori to kill Naganori's former lord, Hatakeyama Nagatsune. In October of the same year, he sent troops to rescue Shiokawa Masatoshi at Ikku Castle in Settsu Province, which was under attack by Miyoshi Norinaga and Masanaga, who were on Harumoto's side, but in November of the same year, he made a peace agreement with Harumoto. In March of the eleventh year of the eleventh year, when Nagamasa expelled his lord, Masakuni Hatakeyama, and tried to welcome his brother, Tanenaga Hatakeyama, from Kii Province, Nagamasa assisted Masakuni in attacking Tanenaga at Takaya Castle in Kawachi Province (Habikino City). However, he was counter-attacked by Nagamasa and Tanenaga, and was defeated in the battle at Taiheiji Temple on March 17 of the same year, captured, and stabbed to death.
