I want to know the answer to the following question:
Who was Ashikaga Yoshimasa?
All the background I'm provided with is that "The fact that Chiyo (though she is better known as "Wife of Yamauchi Kazutoyo") is held in such high esteem for her economic sense is illuminating in the light of the fact that she never produced an heir and the Yamauchi clan was succeeded by Kazutoyo's younger brother.". Is that enough to answer the question?
