Oldest living man in Japan, Mr. Kiyotaka Mizuno (水野清隆) of Iwata City, Shizuoka Prefecture has sadly passed away February 8, 2026 at age of 111 years, 331 days.
He was born on March 14, 1914 in Iwata City. He became ''the oldest living man in Shizuoka Prefecture'' on November 23, 2021, following the death of Mr. Kentarō Muramatsu of Yaizu City. He became ''the oldest living man in Japan'' on August 21, 2024, following the death of an anonymous man in Bunkyō Ward, Tōkyō. On November 9, 2025, following the death of Ms. Yoshi Moriya of Izu City, Mr. Mizuno became ''the oldest living person, including women, in Shizuoka Prefecture.''
In his youth, he served as a guard in the Imperial Guard, and during the February 26 Incident in 1936, he was assigned to guard the Imperial Palace. When he was called up for duty during the Second Sino-Japanese War, he fought in various parts of China, including the Wengying Operation and the Binyang Operation. After the outbreak of the Pacific War, he was transferred to a unit organized in Manchuria and headed south via Hakata, but his transport ship was torpedoed and sunk off the coast of the Philippines. He was rescued by a naval boat and landed on Celebes Island, where he remained until the end of the war. After returning to Japan, he worked as a farmer until he was about 85 years old, cultivating green onions and shrimp potatoes.
