Nikko National Park - Nasu Heisei-no-Mori Forest

After the marriage of Emperor Shōwa, the Nasu Imperial Villa was established in 1926 as a retreat for the imperial family. The villa is surrounded by a rich forest, home to a diverse range of flora and fauna, including rare species. In commemoration of the 20th anniversary of Emperor Emeritus Akihito's reign, approximately half of the villa's land—about 560 hectares—was transferred from the Imperial Household Agency to the Ministry of the Environment. This area was subsequently opened to the public in May 2011 as Nasu Heisei-no-Mori Forest, part of Nikko National Park.

Nasu Heisei Forest is home to a variety of trees, including mizunara oaks and konara oaks, with streams like the Yosasa and Shirato rivers flowing through it. The "Fureai no Mori" (Friendly Forest) area offers opportunities for free exploration and nature experiences, centered around the Field Center at the forest's entrance. Accessible pathways, including those for wheelchair users, and a walking trail leading to the Komadome Waterfall observation deck allow visitors to enjoy the forest not only in summer but also in winter with snowshoe rentals available.

The "Guide Walk" through the "Manabi no Mori" (Learning Forest), a guided-only area, is also popular. For beginners, a 1.5-kilometer course that takes about two hours is available. The guide walks change themes monthly, ensuring that visitors can enjoy the rich forest from various perspectives no matter the season.
