Isshuzaka
During the fierce battle of the previous nine years, Yawata Taro Yoshiie (Minamoto Yoshiie) sang, ``The clothes are untidy,'' and Abe Sadatoto said, ``As the years go by, the pain of the threads being disarrayed.'' I returned the song. Yoshiie sensed this and did not dare to pursue him.
From this story, this slope is said to be Isshuzaka.
