Ogasawara Nagatada

Ogasawara Nagatada (1202–1264) was a mid-Kamakura warrior and gokenin, the third head of the Ogasawara clan, succeeding his father Nagatsune; he was also called Matsuo Nagatada after his seat at Matsuo in Shinano's Ina district.

In Nagatada's day the clan's standing in Shinano belonged to the Tomono main line, while his elder brother Nagamura fled after backing the Miura in the Hōji War of 1247. His son Nagamasa succeeded him, and Nagamasa's son Nagauji later recovered the family headship.
