Aisu Tsunenobu

Aisu Tsunenobu was a head of the Aisu warrior clan of Kii Province in the Kamakura period. As jitō, steward of the Nambu, Mitsu and Akitsu manors, he built Kinugasa Castle on Mount Kinugasa. His castle overlooked the Nakahechi route of the Kumano road, Tanabe Bay and Akitsuno.

After the Hōji War in 1247 he resigned his stewardship and, in his later years, moved his residence from Nambu Hall to the castle, which became the seat of the Kii Aisu clan.
