Yukichi Chuganji (中願寺 雄吉; "Chūganji Yūkichi", 23 March 1889 – 28 September 2003) was a Japanese supercentenarian who at the time of his death at age 114 years, 189 days was the 4th oldest person ever from Japan as well as the oldest person ever from the island of Kyushu, and the world's oldest living person. However, he was only verified as the oldest living man as the oldest living person was believed to be Kamato Hongo, also from Kyushu, who claimed to be almost one and a half year older but was more likely around four years younger and therefore became disputed.
