Honkadori is a technique of classical poetry. The poet takes a phrase or two from a well-known older poem, so that readers think of the older poem while reading the new one. It flourished in the time of the Shin Kokinshū anthology.
Fujiwara no Teika wrote: Koma tomete sode uchiharau kage mo nashi Sano no watari no yuki no yūgure. There is no shelter to stop my horse and brush off my sleeves, at the Sano crossing, on a snowy evening. Its older model is poem 265 of the Man’yōshū, about rain falling at the same Sano crossing, where there is no house.
