This trend strengthened in the Heian period and when YOSHIMINE no Yasuyo (the prince of Emperor Kanmu) was given the kabane of YOSHIMINE no Ason in 802, the number of people who were from the Imperial Family or had the kabane of Mahito increased who wanted to be given the kabane of Ason.
この傾向は平安時代に一層強まり、802年（延暦21）良岑安世（桓武天皇の皇子）が良岑朝臣姓を賜ると、皇族や真人姓の中からも朝臣賜姓を望む者が増加。
