What was the title of Ozaki Hōsai's only haiku book?

Ozaki Hōsai’s only haiku book was *Daikū*, often translated as *Big Sky*. The collection gathers poems from the intensely solitary final period of his life.

Hōsai was born Ozaki Hideo and became associated with the modern free-verse haiku movement. His work often departed from strict traditional patterns, using plain, exposed language to convey loneliness, poverty, illness, and spiritual searching.

After leaving his career and becoming a lay Buddhist mendicant, Hōsai settled on Shōdoshima in 1926. He wrote more than 4,000 haiku between 1916 and 1926, but *Daikū* was selected and arranged by the poet Ogiwara Seisensui. It was published posthumously in 1926 and expanded in 1945.

The distractors point toward other Japanese literary traditions: *Oku no Hosomichi* is associated with Matsuo Bashō, while *Sarumino* is a haikai anthology. Hōsai’s book is also sometimes encountered through the English title *Right under the big sky, I don’t wear a hat*.
