[Okada Shôshun and his academic achievements].

Okada Shôshun (1827-1897), as the last shogunate healer, was a renowned physician of Kampo medicine in Japan from the late Edo to Meiji period. He came from the school of Taki's orthodox medicine, participated in Yi Xi Fang, and drove the development of Kampo medicine in Japan in the Meiji period. He was taken as one of the Six Sages in Kampo medicine and was believed a driving force in the development and continuation of Kampo medicine in Japan. This was because he was one of the founders of the Wun Zhi Society, opened a hospital for Kampo medicine, had scholarly research papers published in a variety of journals, and served as a professor in He Han Medicine Instructing and Practicing Institute. Okada Shshun was an expert in both medicine and Confucianism. His writings, such as the Medical Records of the Ji Shou Guan and the Biography of the Eight Great Chinese Medical Physicians, are of great value as documents in medical history. Additionally, he also paid great attention to the studies and knowledge dissemination of epidemics. This paper focuses on his life history and academic contribution within the background and the development of Kampo medicine, and provides a reference for the study of modern Kampo medicine in Japan.
