[Heaven or Hell] Numajiri Motoyu, Numajiri Onsen

Do you know a hot spring river of milky white water?

The impressive spot must be one of the best hot springs with an exclusion of the fact:

You will have the brush with death from the toxic gas.


At this place, 4 people were died in 1997 due to the poisoning of volcanic gas.

Today here remains dangerous depending on the weather and ground form.

Please do not approach there if it is not windy.

Even in a windy day, please avoid depressions where the gas may be accumulated.

Steep Route of the Climb

Firstly, please take aim at Tamuraya Ryokan in the spa city.

After that, turn left and pass through a ski site to get to a parking lot.

You need 30 minutes’ hiking through a trail whose condition is very bad.

Shiraito No Taki

You will see a big waterfall along the way.

The waterfall is located down the stream of the springs, so that the water is clouded with the constituents.

The largest amount of discharge in Japan for one spring

You will see an extraordinary spectacle with volcanic smokes!

The smell of volcanic gas (sulfur dioxide and hydrogen sulfide)  is so strong that in a minute or less, you will detect no smell.

This hot water gushing from an old mine is famous for the largest amount of discharge (4,0000 gallons per minute) in Japan for one spring.

Hot Springs River

A small part of the water is piped to inns at the foot of the mountain; the most part is unused and overflowed into the river.

Searching for moderate temperature

The water temperature is extremely hot (160 degrees) and be careful for burn injuries.

I found a place with moderate temperature, being mixed with river water.

Cloud

Weather in mountains is changeable in a short time.

It started to blow strongly, although it can be said safer in terms of the poisoning.

In a frigid climate, I jumped into the river with nothing on.

Soaking

Is this heaven, or hell?

I felt as if I were at one with great nature, being washed out by overwhelming amount of hot water.

Summary

😆 Pros

Unbelievable amount of hot water in wilderness

Possibility of death from toxic gas

Here is another hot spring river, available only in winter.

Hot water gushing from the bottom of the river is mixed with the river water and it enables us comfortable soaking.

It can be said a spot for “a wise man.”
