Shimetarō Hara (原 志免太郎, Hara Shimetarō, 4 October 1882 – 18 June 1991) was a Japanese physician, famous for his research in moxibustion, and active as medical doctor until age 104.^{[citation needed]} At the time of his death at age 108 years, 257 days, Hara had been the oldest Japanese man alive after 109-year-old Nisaburo Matsuyama's death on 3 April 1991,^[1] and was succeeded as Japan's oldest living man by Gihei Oka.^[2] He, and proponents of moxibustion, have attributed his longevity to his practice of moxibustion on acupuncture point ST36 upon himself.^{[citation needed]}
