Hakone Botanical Garden of Wetlands

This botanical garden is located next to Sengokuhara Marsh, a nationally designated Natural Monument. Its recreated wetland habitats allow visitors to observe plants in conditions similar to their natural environments. The garden is home to about 1,700 plant species, mainly those found in wetlands such as marshes, rivers, lakes, and ponds, as well as plants from grasslands, forests, and alpine areas, including rare mountain plants from overseas. Wooden walkways lead visitors through a sequence of environments, from lowlands to alpine zones and from fens to bogs.

Seasonal exhibitions are held throughout the year, introducing the plants and animals of Sengokuhara Marsh through photographs, information panels, and large aquariums. Events such as guided walks are also available, offering detailed explanations while visitors view the plants growing in the garden.
