Jigorou Inokuma

Yawara's grandfather, Jigorou, is a 7th-dan Judo Master and 5-time National Champion. His passion for judo is rivaled only by his love for Yawara and food. He has great expectations for Yawara's career, and is constantly pushing her to do her best and focus primarily on judo. His motto is "Judo was not built in a day". He also does work on the side as a bone-setting doctor.
