Yukichi Chuganji (b. March 23, 1889 – d. September 28, 2003) was a Japanese supercentenarian, the world's oldest person and the world's oldest man until his death at age 114 years 189 days. Chuganji held the title of Japan's and Asia's oldest living man for over 3 and a half years - the longest that this title has ever been held. Chuganji was the last surviving Asian man born before 1894, as his successor as Asia's oldest living man, Kameni Nakamura, was born in late 1894 and was over five and a half years younger than Chuganji. Chuganji was one of the few men to hold the world's oldest person title, along with Emiliano Mercado del Toro in 2006-2007 and Jiroemon Kimura in 2012-present.
