Koishikawa Arboretum

Koishikawa Arboretum has been transferred to the University of Tokyo Forests (Forest GX/DX Co-Creation Center).

As of April 2025, the Koishikawa Arboretum, located in Hakusan, Bunkyo City, has been transferred under the jurisdiction of the University of Tokyo Forests's Forest GX/DX Co-Creation Center (hereafter referred to as 'the Arboretum').The former name of the Arboretum was 'Experimental Arboretum of the Faculty of Agriculture.' It was established in 1909 (Meiji 42) by Professor Seiichiro Ikeno of the Department of Botany, Faculty of Agriculture, for the purpose of conducting research in forest plant physiology, pathology, genetics, and breeding, as well as providing experimental materials. The site was set up by long-term lease of a portion of the northern area of the Arboretum affiliated with the Faculty of Science.Although the area is relatively small at approximately 0.66 hectares, the Arboretum is home to a diverse collection of tree species from both Japan and abroad, totaling around 200 species as of a 1993 survey. Among them, the Arboretum features an abundance of species representative of warm-temperate forests, such as chinquapins and oaks, as well as those typical of temperate forests, including beeches, maples, and hornbeams. Notably, within the beech genus, the garden hosts both Japanese beech (Fagus crenata) and Japanese blue beech (Fagus japonica), along with the extremely rare Fagus multinervis , an endemic species of Ulleungdo Island in Korea. Additionally, the garden includes species such as the yellow buckeye (Aesculus flava), native to North America.

In recent years, the arboretum has been utilized as a practical field site for the Forest Science Fundamentals I course, as well as for providing experimental samples to various forest science laboratories and for training in field survey techniques. In particular, the Laboratory of Forest Botany conducts research using MRI (magnetic resonance imaging) to non-destructively observe water transport within tree trunks, and also studies the artificial cultivation of ectomycorrhizal fungi.


Looking ahead, the arboretum is expected to take advantage of its prime location near the Yayoi Campus, home to the graduate school, and serve not only as a site for forest science field training, but also as a base for social collaboration that doubles as an experimental field. It is envisioned as a common space for interaction with industry and local communities, a pilot site for Forest GX/DX initiatives such as IoT-based phenological and forest dynamics monitoring, and a platform for interdisciplinary collaboration with neighboring institutions such as the Arboretum affiliated with the Graduate School of Science and the University Museum
