A rare moss that grows in clusters in hot spring areas! Gunma Prefecture “Chatsubomi Goke Park”
Deep in the mountains of Gunma Prefecture, there is a place called ``Anajigoku'' where strongly acidic hot water gushes out, making it a truly unexplored region. Although it is a harsh environment for many living things, a type of moss called "Chatsubomi moss" grows in large numbers. In 2015, it wa...
To the park connected to the wetland
At the park reception, souvenirs from the Rokugo area are sold.
There are many narrow mountain roads leading to Chatubomi Goke Park, so it is a sightseeing spot that cannot be reached by large buses.
This area is called ``Kuni'' and is located deep in the mountains in Nakanojo, Gunma Prefecture.
The park entrance is located far away from the reception and is reached by a special bus.
At the shop near the reception office, you can find colorful and comfortable-looking crafts such as ``konkon zori,'' as well as local foods.
It's convenient to have a cane available for anyone to use!
After traveling for a while on a private bus, you will arrive in front of the promenade leading to the Chatubomi moss colony.
The promenade is a gentle slope, but it's much easier to walk with a cane. A cane is placed at the entrance.
The promenade is easy to walk, but there are also stairs made of wooden boards, so it's best to dress light.
The color of the river is red. This is a "red" color.
The river that flows beside the promenade has a reddish-brown color.
This is the color of a part of iron ore called limonite.
In the past, the red parts brought from here were used as a material for paint.
Chatubomi moss takes tens of thousands to hundreds of millions of years to transform into iron ore.
It's amazing how moss can produce minerals!
"Chatsubomi moss" is the most acid-resistant of all moss!
As you go deeper, there is a place where hot spring water gushes out.
As you get closer to ``Anajigoku'', you can smell the smell of sulfur.
If you go to the back, you can see up close the point where hot water is gushing out.
Although the spring quality is strongly acidic, it is the perfect growing environment for Chatubomi moss!
Among the types of moss, it is unique in that it is highly acidic.
What is the origin of the name “Ana Jigoku”?
In the past, iron ore was mined in this area by open-pit mining, which involves digging underground from the ground.
The concentration of the acidic spring that gushes out is so high that if an animal falls into this hole, it may be unable to escape and die.
Because of this, it came to be called "hole hell".
Nowadays, the moat has been demolished and a promenade has been constructed so that you can enjoy the scenery safely.
A walking path where you can enjoy the colors created by natural phenomena
The green carpet that grows densely on the rugged earth is a rare sight!
Some parts of Chatubomi moss will wither due to sunburn in the summer, so the best time to see it is from spring to early summer and fall.
The autumn season with beautiful colored leaves is also beautiful.
Beyond Anajigoku, there is also a hiking trail where you can walk through the wetlands.
This is an area where you can see valuable alpine flora and fauna.
