Chō Tsugutsura served as a bushō during the Sengoku period. Tsugutsura was born as the second son of Taira Nobumitsu (the second son of Chō Noritsura).
Tsugutsura served as a senior retainer across four generations of the Hatakeyama clan. Initially, he had the name of Taira Katsumitsu but later he became the adopted son-in-law of his uncle, Chō Hidetsura and received one of the characters in his name from his lord, Hatakeyama Yoshitsugu, adopting the name of Chō Tsugutsura. He was also known as Shinkurō, Kurōzaemon, and the title of Governor of Tajima. Tsugutsura served as the lord of Anamizu Castle in the Fugeshi District of Noto Province.
Tsugutsura was a member of the Hatakeyama Group of Seven, a political organ comprised of senior retainers of the Noto-Hatakeyama who conducted affairs of the clan by means of a council over a period of years. He was involved in the ouster as well as the backing of several lords. In 1566, Tsugutsura joined with Yusa Tsugumitsu to launch a coup d’état by which Hatakeyama Yoshitsuna and his father, Hatakeyama Yoshitsugu, were ousted from Noto in an event known as the Political Incident of Eiroku 9. Tsugumitsu was a fellow member of the Hatakeyama Group of Seven who was also Tsugutsura’s brother-in-law having married the daughter of Taira Nobumitsu.
After the power of Oda Nobunaga extended into Noto Province, Tsugutsura cultivated friendly relations with the Oda, causing differences between Tsugutsura and senior retainers from the Yusa and Nukui clans favoring the Uesugi over the Oda. Tsugutsura rose to prominence, becoming the most powerful among the senior retainers of the Noto-Hatakeyama clan.
Beginning in 1576, Uesugi Kenshin of Echigo commenced an invasion of Noto, but by holing-up in the stronghold of Nanao Castle, Tsugutsura was able to repel them the first time in an event known as the Siege of Nanao Castle. However, in 1577, while Tsugutsura once again engaged in battle against the Uesugi army, he fell ill in the castle and the situation became unfavorable for the defenders. At this time, Yusa Tsugumitsu and Nukui Kagetaka colluded with Kenshin and the castle fell.
Tsugutsura and most of the Chō family were slayed in the castle several days before the arrival of reinforcements from the Oda brought by Chō Tsuratatsu (Tsugutsura’s third son) who had secretly been dispatched to seek their help.
