In 1336, the forty-fourth generation Koremura SHIROFUJI set fire to the warships of Takauji ASHIKAGA who was routed from Kyoto on the day when the north wind blew hard and made a great victory, and so he was given the name Sadamura KITAKAZE (喜多風貞村, of which 喜多風 is pronounced in the same way as 北風 [north wind]) by Yoshisada NITTA.
