Onuma Pond Nature Trail Map
Onuma Pond is 250 meters ahead.
The pond, which has a surface area of approximately 4 hectares, is surrounded by wetlands. Those on the south side are particularly well-developed. The wetlands are home to mizubasho (Asian skunk cabbage), false hellebore, cotton grass, marsh tea, and other plants that thrive in humid conditions. These plants bloom in early spring; in fall, look for the purple blooms of the ezo-oyamarindo gentian.
Immediately surrounding the wetlands are forests dominated by Japanese beech and oak trees interspersed with a scattering of stands of Maries’ fir and Japanese white pine.
Please stay on the wooden boardwalk, which has been built to protect the delicate wetland vegetation.
