Yosa Buson
Hagiwara's second anthology, "Aoneko" ("Blue Cat") was published in 1923 to even greater acclaim and "Tsuki ni Hoeru". The poems in this anthology incorporated concepts from Buddhism with the nihilism of Arthur Schopenhauer. Hagiwara subsequently published a number of other volumes of cultural and literary criticism. He was also a scholar of classical verse and published "Shi no Genri" ("Principles of Poetry", 1928). His critical study "Ren'ai meika shu" ("A Collection of Best-Loved Love Poems", 1931), shows that he had a deep appreciation for classical Japanese poetry, and "Kyōshu no shijin Yosa Buson" ("Yosa Buson—Poet of Nostalgia", 1936) reveals his respect for the "haiku" poet Buson, who advocated a return to the 17th century rules of Bashō.
