Nonaka was certified as the oldest man alive in April of last year, shortly before his celebration of his 113th birthday. He was born July 25, 1905 – the same year that Albert Einstein developed his revolutionary theory of relativity, according to Kyodo News.
Nonaka died peacefully Sunday in his sleep, said his family at the spa inn that his family owned and operated for over 106 years.
Nonaka was limited to a wheelchair during his last years, but he could move independently and continued to enjoy the simple things of life until the last day. He would have liked to read, watch TV, eat treats after every meal and soak in a hot spring once a week.
His granddaughter, Yuko, said that Nonaka had no health problems. He died peacefully.
"We are shocked by the loss of this great figure," she said. "His last moments were calm, he died without causing any problems to our family."
"I had a lot of quarrels with him, but we enjoyed being together," she continued. "I am filled with feelings of gratitude."
Nanoka has survived the vast majority of his immediate family, including his seven brothers and sisters, his wife, and three of their five children.
The Japanese Ministry of Health, Labor and Welfare announced last year that the country had 69,785 citizens over 100 years old, 90% of them women. In fact, the woman currently recognized as the oldest living person is also the Japanese, Kane Tanaka, 116 years old.
