In 1581 (Tenshō 9), Maeda Toshiie, a vassal of Oda Nobunaga, was granted the entire Noto Province. Toshiie and his descendants, the Maeda lords of Kaga Domain, became devoted patrons of Keta Taisha. Through their support, the main hall, worship hall, shrine gate, and other structures — five buildings in total — were constructed, all of which remain today as National Important Cultural Properties.
