Located in Akita Prefecture within the Hachimantai National Park, Oonuma Marsh offers a serene escape into nature. Accessible via bus from Hachimantai Summit Bus Stop (seasonal operation from April to November), this highland marshland features a 1.2-kilometer boardwalk trail that loops around the scenic Oonuma Pond. Visitors can enjoy seasonal flora such as Mizubasho, Iso-Tsutsuji, and vibrant autumn foliage. The trail is mostly flat, making it suitable for all fitness levels, though hiking shoes are recommended due to potentially slippery sections. The Hachimantai Visitor Center nearby provides parking and information.
