Senjogahara marsh

Senjogahara marshOku-Nikko area mapSenjogahara is a marsh extending to the north of Lake Chuzenji and to the west of Mount Nantai.

It is located at the level of about 1,400 meters, and the width is about 400 hectares.
From north to south, Yukawa River flows through this marsh. At the south end of the marsh, there is Ryuuzu Falls on the river and the river flows into Lake Chuzenji.

This marsh is classified into intermediate moor or high moor, then we can enjoy alpine plants from June to August.
And a lot of wild birds inhabit this area.

To the west of Senjogahara, Odashirogahara grassland spreads.
This is the popular spot in this area, and we can see many native wildflowers in summer.

About 20 thousand years ago, when Lake Chuzenji was formed after the erruption of Mount Nantai, a large lake also was formed in current Senjogahara around the same time.
After that, earth and sand had deposited for a long period of time, then current marsh has been formed.

"Senjogahara" means "field of battle ".
In the age of god, the god of Mt. Nantai and the god of Mt. Akagi (Gunma Prefecture) had fought for the ownership of Lake Chuzenji.
The god of Mt. Nantai changed himself into a lot of snakes, and Mt. Akagi changed himself into many centipedes, and they had a battle at this area.
Therefore, this name of "Senjogahara" was given this field.
(Of course, Mt. Nantai won.)

Through the east part of this, Route 120 runs. The road runs from central Nikko, through Iroha-zaka, Lake Chuzenji and this area, to Lake Yunoko.
Basically, a few bus stops or parking areas on this route are the starting points to tour, and please hike from there.
