Significance

In 1774, a group of Japanese physicians led by Sugita Genpaku published Kaitai Shinsho ("New Book of Anatomy") in Edo, the first complete Japanese translation of a Western scientific text.

The work rendered into Japanese the Dutch anatomical atlas Ontleedkundige Tafelen, itself derived from Johann Adam Kulmus's German Anatomische Tabellen (Latin Tabulae Anatomicae, Gdansk, c. 1722). Sugita and his collaborators, including Maeno Ryotaku, Nakagawa Jun'an, and Katsuragawa Hoshu, had been struck during a 1771 dissection by the accuracy of the Dutch illustrations compared with received Chinese medical teaching, and spent roughly three years and eleven drafts completing the translation with only a meager Dutch vocabulary. To convey unfamiliar concepts they coined new Japanese terms such as shinkei (nerve) and domyaku (artery) that remain in use today. The book demonstrated that European learning could be accessed despite the Tokugawa policy of national seclusion (sakoku) and became the foundational achievement of Rangaku, the systematic study of Western knowledge through the Dutch language at Dejima, profoundly shaping Japanese medicine, science, and the eventual modernisation of the country.
