Institute for Nature Study, Botanical garden and natural monument in Shirokanedai, Tokyo, Japan.
The Institute for Nature Study is an urban forest reserve in Tokyo that spans multiple hectares and contains diverse habitats including woodlands, marshes, and open areas. The grounds preserve hundreds of plant species native to the original Musashino region before the city expanded around it.
The site began as a temple estate and later became a samurai residence before becoming an imperial nature reserve in 1949. Archaeological findings show that people occupied this land during the Jomon period, thousands of years before modern Tokyo developed.
The land reflects its past as a feudal residence through its layout and carefully maintained sections that blend garden design with wild plant communities. Visitors can observe how this space connects people to the natural world in a distinctly Japanese way, balancing human use with ecological respect.
The site is best visited in fall and spring when the weather is mild and plants are actively growing. Wear sturdy shoes and allow plenty of time to explore, as the paths wind through different habitats and there is no quick route through the grounds.
The site shelters uncommon animals such as raccoon dogs and mandarin ducks, species that have few other places to survive within this major city. These creatures demonstrate how vital this small green space is for wildlife surrounded by dense urban development.
