Traditional medicine never lost its popularity throughout the Edo period, but it entered a period of rapid decline shortly after the Meiji Restoration. In 1871, the new government decided to modernize medical education based on the German medical system. Starting in 1875, new medical examinations focused on natural sciences and Western medical disciplines. In October 1883, a law retracted the licenses of any existing traditional practitioner. Despite losing legal standing, a small number of traditional physicians continued to practice privately. Some of them, such as Yamada Gyōkō (1808–1881), Asada Sōhaku (1813–1894), and Mori Risshi (1807–1885), organized an "Association to Preserve Knowledge" ("Onchi-sha") and started to set up small hospitals. However, by 1887, the organization was disbanded due to internal policy dissent and the death of leading figures. The "Imperial Medical Association" ("Teikoku Ikai"), founded in 1894, was short-lived too. In 1895, the 8th National Assembly of the Diet vetoed a request to continue the practice of Kampō. When Azai Kokkan (1848–1903), one of the main activists, died, the Kampō-movement was almost stamped out.
