 In 1919, Horiguchi published his first anthology of verse, "Gekko to Pierrot" ("Moonlight and Pierrot"), and a book of waka verse, "Pan no fue" ("Pan pipes").On returning to Japan in 1925, he brought out a collection of poems "Gekka no ichigun", which introduced the Japanese literary world to the works of Jean Cocteau, Raymond Radiguet, Paul Verlaine, and Guillaume Apollinaire.This work greatly influenced modern Japanese poetry starting from the late 1920s and 1930s.
