Nisaburo Matsuyama (10 October 1881 – 3 April 1991) was a Japanese centenarian and from the 6 March 1990 death of Kiichi Fujiwara until his own death in Komatsu, Ishikawa prefecture, on 3 April 1991 aged 109 years, 175 days, Japan's oldest living man. Some reports mistakenly stated he died a year earlier. Matsuyama's wife died in 1951, and he was still able to work his farm until he was around 104. His fifth daughter reported that he was bedridden near his death but still enjoyed newspapers and television, and attributed his longevity to a policy of "don't worry and moderation in eating."
