恩賜上野動物園
After the Meiji Restoration, the Japanese Civil Service was reorganised. Within the "Daigaku" (later the Ministry of Education) Tanaka joined the Bureau of Local Products, and then moved to the Museums Bureau in 1871. A decade later, his services were sought by the Ministry of Agriculture and Commerce to oversee the menagerie attached to the National Museum of Natural History; Tanaka took advantage of the opportunity to create Ueno Zoo. Opened in 1882, it was Japan's first zoological park. The creation of the zoo resulted in Tanaka's promotion to Director-General of the Natural History Bureau, however he received little ministerial support for his botanical and zoological planning and resigned from the post the following year.
