Since his family moved to Matsusaka, Yasujiro was transferred to the 4th year of Daini Jinjo Elementary School.

He wrote in his diary on January 1, 1918, “... There was a first-pitch ceremony in the afternoon at Kanbe School (Now: Daigo Elementary School) because the windows of Daini School sometimes get broken. There were no balls, so we went to Inuiʼs house and played Karuta (a Japanese card game)...”

Yasujiro must have enjoyed his school days, playing with his friends.
