Taro Yashima is the assumed name of children’s author and illustrator Jun Atsushi Iwamatsu. Born in the Japanese countryside to a local doctor and his wife, as a young man he found the rise in militarism prior to his country’s invasion of China and attack on America to be very much against his personal beliefs. He and his wife Tomoe, also an artist, joined peaceful protest groups called “culture clubs” that used their art to make anti-authoritarian statements about Japan’s government and the harsh conditions people lived under to support the military as it readied for war.
