Asukai Masatsune (飛鳥井雅経, 1170–1221) was a Japanese waka poet of the early Kamakura period.
[3][4] He was a son of Nanba Yoritsune (難波頼経, Japanese Wikipedia),[1] and the ancestor of the Asukai family, who were known for their skill at both poetic composition and kemari.
Masatsune served three emperors, Go-Toba, Tsuchimikado and Juntoku, in addition to working under the Kamakura shogunate.
[1] Masatsune studied waka under Fujiwara no Shunzei and from 1201[3] served in the Poetry Bureau (和歌所, Waka-dokoro).
[3] He also compiled a private waka collection, the Asukai-shū (明日香井集, also called Asukai Wakashū, 明日香井和歌集[2]), which was edited by his grandson Masaari in 1292.
