He had been influenced by the work of Danish surgeon Severin Nordentoft. In 1922, he went to Germany to study the use of x-ray technology there. Following World War II, Takagi's pupil Masaki Watanabe, carried on his work.

Later, he personally studied leprosy at his house, and died in 1974.

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, 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.
Mokichi Saitō (斎藤 茂吉, Saitō Mokichi; Japanese pronunciation: [sai.toː (|) mo.kʲi̥.tɕi], May 14, 1882 – February 25…Mokichi Saitō (斎藤 茂吉, Saitō Mokichi; Japanese pronunciation: [sai.toː (|) mo.kʲi̥.tɕi], May 14, 1882 – February 25, 1953) was a Japanese poet of the Taishō period, a member of the Araragi school of tanka, and a psychiatrist. Mokichi was born in the village of Kanakame, now part of Kaminoyama, Yamagata in 1882. He attended Tokyo Imperial University Medical School and, upon graduation in 1911, joined the staff of Sugamo Hospital (present-day Tokyo Metropolitan Matsuzawa Hospital) where he began his study of psychiatry. He later directed Aoyama Hospital, a psychiatric facility. Mokichi studied tanka under Itō Sachio, a disciple of Masaoka Shiki and leader, after his master's death, of the Negishi Tanka Society; Sachio also edited the society's official journal Ashibi. This magazine, due to Sachio's increasing commitment to other literary activities, was subsequently replaced by Araragi in 1908. The publication in 1913 of Mokichi's first collection of tanka, Shakkō ("Red Light") was an immediate sensation with the broader public. The first edition collected the poet's work from the years 1905-1913 and included 50 tanka sequences (rensaku), with the autobiographical "My Mother is Dying" (死にたまふ母, Shinitamafuhaha) being perhaps the most celebrated sequence in the book. Mokichi's career as a poet spanned almost 50 years. At the time of his death at the age of 70, he had published seventeen poetry collections which include "14,200 or so poems," the collected works being overwhelmingly devoted to tanka. In 1950 he received the inaugural Yomiuri Prize for poetry. He received the Order of Culture in 1951. Mokichi was the family doctor of author Ryūnosuke Akutagawa and may have unknowingly played an indirect role in the latter's suicide. He also wrote philological essays on waka of Kakinomoto no Hitomaro and of Minamoto no Sanetomo.
Kyusaku Ogino (荻野 久作, Ogino Kyūsaku; 25 March 1882 – 1 January 1975) was a Japanese medical doctor specializing in…Kyusaku Ogino (荻野 久作, Ogino Kyūsaku; 25 March 1882 – 1 January 1975) was a Japanese medical doctor specializing in obstetrics and gynecology. His natural father's family name was Nakamura, but Kyusaku was adopted by the Ogino family in 1901. Ogino studied infertility and developed a method to estimate the fertile period of the menstrual cycle based on the length of a woman's past cycles. This knowledge could be used by couples seeking pregnancy to time intercourse so as to maximize the chances of conception. In 1930, John Smulders, Roman Catholic physician from the Netherlands, used this discovery to create a method for avoiding pregnancy. Smulders published his work with the Dutch Roman Catholic medical association, and this was the official Rhythm Method promoted over the next several decades. Ogino opposed the use of his method for contraception. He argued that its failure rate was too high: to promote it for contraception, despite the availability of other effective contraceptive methods, would result in many abortions from unwanted pregnancies. Despite this, the Rhythm Method of contraception is ironically referred to as the Ogino Method (オギノ式, ogino-shiki) in Japan. Babies born to parents using this method are known in France as "bébés Ogino."

Under threat of legal harassment by antivaccine activists, publishers declined some of her works including a book on the HPV vaccine (ultimately, Heibonsha accepted the book for publication).
