Wada Koremasa (和田 惟政, 1536–1571) was samurai and senior retainer of the Ashikaga Shogunate.[1] The Wada clan were a powerful ninja family in the Kōka ikki in Kōka District until Koremasa was granted land in Settsu Province in 1568 as a reward for his support for Ashikaga Yoshiaki and Oda Nobunaga.
Nobunaga held him in high regard.[1] Koremasa was appointed as the lord of Takatsuki castle and given part of the Settsu province.[1] He secured an audience between Oda Nobunaga and the Jesuit Missionary Luís Fróis, and was a staunch supporter of the Catholic Church throughout his life.[2][3] Koremasa fought against Settsu Ikeda clan and died during the battle of Shiraigawara in 1571, being killed by Araki Murashige.[1][2][3]
