It is said that, although initially calling himself 'Kadenokoji' after the street along which his residence was placed, he changed his family name to 'Yoshida' because he later built another residence in Yoshida in the east suburb of the capital.
初めは邸宅のあった通りより、「勘解由小路」と名乗っていたが、後に京の東郊・吉田に別邸を建てたために家名を「吉田」と改めたとされる。
