The Tazakis' sole daughter, Keiko, was born with severe disabilities, being deaf, mute, and mentally impaired. Her parents attempted to accept her condition, yet their anguish persisted. A shift occurred once Keiko enrolled in a school for the deaf and mute. Through the friendship and cooperation of teachers and peers, not only Keiko but also her parents matured. They formed a group called "Donguri" (acorn) to create a community workshop enabling disabled individuals to achieve independence.
