(Ishi, p. 56) Although he had previously been using the pen name of "Hōsai" written with the characters "芳哉", during this period he gradually shifted to using "放哉" (pronounced identically).
(Ueda, p. 81) During the same period, although all of the other employees wore business suits, Ozaki owned no clothing other than a tuxedo and a pair of pajamas.
In 1926, he settled on the island of Shōdoshima, Kagawa Prefecture, in the Inland Sea, and was given the post of rector of the small hermitage of Minango-an at the temple of Saiko-ji.
His only book, Daikū (大空, Big Sky), contains poems of his solitary final years, and was selected by Ogiwara Seisensui from the over 4,000 haiku composed by Ozaki between 1916 and 1926.
Portions are available in English translation by Hiroaki Sato entitled Right under the big sky, I don't wear a hat (ISBN 1-880656-05-1).
