The Oku-Nikko region is home to abundant natural beauty, featuring waterfalls, lakes and high marshlands.
The Oku-Nikko region is located in the northwestern part of Nikko in western Tochigi, and it is included as part of the Nikko National Park.
Kegon-no-taki Fall, know is one of the three most famous waterfalls in Japan, drops from a 100 meter-high cliff. An observation point at its bottom offers a spectacular view. At the foot of Mt. Nantai lies Lake Chuzenji. Not only can you fish for himemasu (kokanee salmon) and nijimasu (rainbow trout), the lake also provides a magnificent view of Mt. Nantai from its sightseeing boats.
North of Lake Chuzenji are additional waterfalls, Ryuzu-no-taki and Yu-daki, which is at the southern end of Lake Yuno. Also in this area is Senjogahara, a marshland region where alpine plants and marsh plants grow. This marshland region, which features a nature observation path, is a notable attraction for those who enjoy outdoor activities like birdwatching and hiking.
In its northern reaches, the Oku-Nikko area has the Yumoto and Kotoku onsen, camping sites, a ski resort, and the Sugenuma and Marunuma fishing ponds. The natural beauty of Oku-Nikko provides a wonderful compliment to Nikko's primary attraction, the Toshogu Shrine.
