Nagatoki Ogasawara - Nagatoki Ogasawara

A military commander in the Sengoku period. He was born on November 23, 11th year of the Eisho era, at Fuchu Hayashi Castle as the eldest son of the Fukashi family, the main line of the Ogasawara clan, which inherited the position of Shugo of Shinano. His childhood name was Toyomatsumaru. According to the Mizoguchi Family Records, compiled in 1608 (Keicho 13) by Mizoguchi Sadayasu for his lord Ogasawara Hidemasa, he was born in 1518 (Eisho 15). He ruled over the counties of Chikuma and Azumi, as well as the Kamiina region, and fought against the conquest of Takeda Shingen during the Tenbun era (1532-55). In 1550 (Tenbun 19), he lost his base in the capital and allied with Murakami Yoshikiyo to maintain his position in Azumi, but in 1552 he was driven out of Shinano and became a ronin (masterless samurai). After passing through Echigo, Nagatoki and Sadayoshi traveled to Kyoto, where they maintained close ties with nobles such as Hirohashi Kunimitsu and Yamashina Tokitsugu, and stayed in Akutagawa Castle in Settsu Province during the Eiroku period (1558-1570) relying on Miyoshi Nagayoshi. During this time, he attempted to return to Japan through the shoguns Ashikaga Yoshiteru and Uesugi Kenshin, but failed. Having lost his base when Oda Nobunaga attacked Miyoshi, Nagatoki became a wanderer, while his son Sadayoshi served Ieyasu, and in July 1582 (Tensho 10), he regained control of Fukashi Castle. Nagatoki's actions during this time are unknown, and he was killed by his vassals on February 25th of the following year (Tensho 11).
