Takaie Oyamada was a Japanese warrior, one of the Seven Tribal Chieftains of Musashi Province (around Tokyo).
Takaie Oyamada was born in Japan.
Followed Yoshisada Nitta and fought for the cause of the South Imperial Dynasty. As a vassal of Yoshisada, he besieged Norimura Akamatsu at Shirohata Castle. At the time, Yoshisada enforced strict discipline among his forces and did not allow them to even take an ear of barley from farmers. But Takaie's soldiers took barley plants growing in the enemy territory. Noticing this, Rokuro Nagahama, an attendant of Yoshisada, reported it to his lord. Yoshisada made inquiries and found out that Takaie had no food for his troops and did not punish him.
Instead he gave Takaie food rations and gave clothes to the farmer from whose fields Takaie had taken barley. Takaie was much impressed by Yoshisada's action. Later, when Yoshisada was defeated in a battle with Takauji Ashikaga in Hyogo and was about to be captured by the enemy upon his horse being disabled,Takaie gave his mount to Yoshisada and was killed fighting single-handed. Yoshisada made good his escape.
