As of 2005, he had 22 grandchildren and great-grandchildren, and he lived with his eldest son. At the age of 100, his legs were not so strong anymore, but his eyesight and hearing remained good.

He also enjoyed spending time each day drinking tea, chatting, and watching his favorite period dramas on television.

In September 2015, he celebrated his 110th birthday, becoming the first male supercentenarian in Miyagi Prefecture.
