Kaifūsō

The is the earliest extant anthology of literary Sinitic poetry (kanshi) written by Japanese poets.

It was compiled in 751. In the brief introduction of the poets, the unknown writer seems sympathetic to Emperor Kōbun and his regents who were overthrown in 672 by Emperor Tenmu after only eight months of rule. Thus, it has been traditionally credited to Ōmi no Mifune (722–785), a great grandson of Emperor Kōbun. It also has been said that Fujii no Hironari (n.d., fl. first half of 8th century) and Isonokami no Yakatsugu (729–781) could be the compiler.
