[Heaven or Hell] Numajiri Motoyu, Numajiri Onsen

Do you know a hot spring river with milky-white water?

It can be said that the impressive spot is the best hot spring with the exclusion of the fact:

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


At this place, four 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 here if it is not windy.

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

Steep Route of the Climb

You will pass some Ryokans and a ski site, so that you will get to a parking lot.

Thirty minutes’ trail is necessary from the parking.

Even though it is only thirty minutes, the route condition is extremely bad.

Shiraito No Taki

You will see the big waterfall along the way.

This waterfall is located down the stream of the river where you will visit from now; the water is clouded with the constituents.

The largest amount of discharge in Japan for one spring

You will find an extraordinary spectacle with volcanic smokes.

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

The acid hot water upwelling from an old mine is famous for the largest amount of discharge (four thousand 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; and the most part is unused and overflowed into the milky-white river.

Searching for moderate temperature

The water temperature is around 160 degrees and be careful for burn injuries.

I searched for points of moderate temperature, being mixed with river water.

Soaking (near)

Weather in mountains is changeable in a short time.

I visited there in October and 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 (distant)

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.

There is a proverb, “a wise man keeps away from danger.”

Sennin Buro

Sennin Buro, Kawayu, Onsen, Wakayama, Japan

This is a large open-air bath made by damming a river, available only in winter (from December to February.)

Hot (about 160 degrees) water upwelling from bottom of the river is mixed with river water and it enables us comfortable soaking.

It can be said a spot for “a wise man,” because it is much safer and complimentary.
