In 1917 (Taisho 6), Ryokuseki Kawamoto and Kenji Miyazawa, Kanai Hosaka, Kenkichi Kosuge and others published the coterie literary magazine "Azalea" and influenced each other. After graduating, Ryokuseki returned to his hometown of Tottori, where he taught at Kurayoshi Agricultural High School, demonstrating his wide range of talents, including haiku, painting, and writing poetry.

In 1924, Kenji Miyazawa, who also taught at an agricultural school, gifted Ryokuseki his first collection of poems, "Spring and Shura" and "The Restaurant with Many Orders." Ryokuseki was deeply moved by his gesture, and he published a collection of poems “Fragments of Dreams” in response to Kenji's friendship.

However, in the summer of 1933, he went to rescue a colleague who drowned during sea bathing training, and died at the age of 37. His death also shocked Taneda Santoka, who was a student of Seisensui Ogiwara, who was also at the center of the free-style haiku movement. His sorrow is engraved on the memorial tower of Ryokuseki in Yabashikaigan where he died. 

Two months after Ryokuseki's death, Kenji also passed away. It is often said among Kenji’s researchers that in his posthumous book “Night on the Galactic Railroad,” “Campanella” who died saving a drowning friend was modeled on Ryokuseki. 

Ryokuseki was not only a brilliant poet but also a good father at home and a good teacher at school who cared about his students and colleagues. He had a great life. 

At that time, Ryokuseki was the only person in the village of Fukumitsu to own a bicycle, and when he was a teacher at Kurayoshi Agricultural College, he commuted to work on his bicycle every day. The morning of the day when Ryokuseki rescued a drowning colleague during swimming class and died, it is said that Ryokuseki, who rode his bicycle as usual, stopped many times that morning and looked back at his house with a fondness and a feeling that it would be difficult to leave.

In Kenji Miyazawa's "Night on the Galactic Railroad," there is a scene in which Campanella asks Giovanni, "Will your mother forgive me?" Giovanni didn’t know this but Campanella had saved a drowning friend and drowned himself by this time. His only regret was for his mother. His appearance and the cause of his death seem to coincide with Ryokuseki of the last day, which is why it is speculated that Campanella was Ryokuseki.
