Nikko Botanical Garden was established in 1902 as an educational and research branch of the main Botanical Garden of the Faculty of Science, University of Tokyo ("Koishikawa Botanical Garden," at Tokyo), for the study of alpine plants. At that time, Nikko Botanical Garden was located near the famous Toshogu Shrine. The garden was moved to the present area in 1911. A part of garden of the "Tamozawa Goyotei", a villa of the imperial family, was donated to or purchased by the Botanical Garden in 1950, thereby enlarging the area to 106,980m2.

Most of woody species in the Garden are indigenous to Japan. They were planted in their present site as early as the foundation of the Botanical Gardens and have now reached the size of natural state.

There are good collections of woody representatives of the Japanese temperate flora, including 22 of the 24 indigenous Japanese species of Acer, more than 10 species of Japanese Cerasus (Prunus ), and 80 species of evergreen and deciduous rhododendrons (species from abroad included).


Many herbaceous species are grown under the shade of the trees and at their margins. To maintain plants that need special surroundings, rockeries and bog gardens have been established.

About 100 species of Japanese alpine plants are grown in the rockeries gardens. Plants from abroad, such as the Himalayas and Korea, are also cultivated.

Aquatic plants such as Equisetum fluviatile are grown in the bog gardens. Parts of this area are provided artificial raised bogs with bog mosses where the characteristic bog plants are cultivated.
