Shimetarō Hara
Shimetarō Hara was a Japanese physician, famous for his research in moxibustion, and active as medical doctor until age 104. At the time of his death at age, Hara had been the oldest Japanese man alive after 109-year-old Nisaburo Matsuyama's death on 3 April 1991, and was succeeded as Japan's oldest living man by Gihei Oka. He, and proponents of moxibustion, have attributed his longevity to his practice of moxibustion on acupuncture point ST36 upon himself.
