Note that some shogun changed their names and some were received a character of his former given name (such as 'ki' [材] of Yoshitane ASHIKAGA [former Yoshiki, 義材], 'taka' [高] of Yoshizumi ASHIKAGA [former Yoshitaka, 義高], and 'fumi' (藤) of Yoshiteru ASHIKAGA [former Yoshifumi, 義藤]).
なお、歴代将軍の中には中途で改名したものもおり、改名以前にその当時の下の字が与えられている例もあるので注意を要する（足利義稙（義材）の「材」、足利義澄（義高）の「高」、足利義輝（義藤）の「藤」など）。
