Answer
The Kokuchūkai was a Japanese Buddhist organization that Kenji Miyazawa joined in 1919. The group believed in the fusion of Zen and Pure Land Buddhism and emphasized spiritual awakening through daily life experiences and activities. Members practiced zazen meditation and engaged in social work and education. Miyazawa found solace in the Kokuchūkai's teachings during a challenging period of his life, and his experiences within the organization influenced his literary works.
