"Koganenoyu", that has been in Ikaho since ancient times, is Flowing without circulation. At a reasonable charge, you can easily enjoy the greenish-brown hot water typical of Ikaho Onsen.

It's a communal bath with a Japanese traditional exterior that goes well with the atmosphere of Ikaho Onsen. You can go out to the veranda from the bathing room and enjoy the view of mountains. The terrace outside the break room has a wood deck, which is good for cooling off after the bath.

Travel journal of day trip bathing to hot spring


He is an orthodox hot springs lover and particular about quality of springs. He loves the hot springs flowing from the source, the hot water with a presence, and the rustic atmosphere.
He doesn't care much about quality of hot springs. He loves the open-air bath, and prefers hot springs that have visible features such as good views.

Today, Nishi-san and Kita-san came to Ikaho Onsen on a day trip. From Shibukawa Station to Ikaho Onsen by bus, they started going up the stone steps, aiming for "Ishidannoyu". A hot spring flows in the center of the stone steps, and the stones are dyed vermilion.

Hot spring flowing the stone steps

Hey! The stone steps are reddish-brown. It feels like we've come to Ikaho Onsen.

Wow! you can also take a footbath here.

The stone steps are still new, but have been so red. In short, it has a lot of iron.

Soon after they started going up the stone steps, they arrived at Ishidannoyu. The exterior is a Japanese traditional style with white walls and tiled roof.

Ikaho Onsen is a historical hot spring that is mentioned in "Manyoshu". ("Manyoshu" is Japan's oldest collection of poems compiled in 783 AD.)

The extension of the lower part of the stone steps was completed in 2010.

Oh, it's already over. The building is Japanese-style, but it's pretty neat.

It's like new.

Ishidannoyu bathtub, Ikaho Onsen


Ishidannoyu can be crowded with tourists during the busy season. This day was just after the summer vacation, so it was relatively uncrowded.

Bathing room isn't purely Japanese. It's a bit retro-like.

The hot water is also good. It's nice to feel like simple overall.

The hot water spout of raccoon dog is also getting reddish, you know.

It's a lion.

Huh? Really? It looks like a raccoon dog.

A lion! It's a lion, of course!

Is that so? I think it's a raccoon dog ...

Nishi-san and Kita-san enjoyed the hot spring water of Ishidannoyu slowly and came out to the break room.

Ishidannoyu was reopened in 2003.

View from break room

It's a pretty good view. Is that Mt. Akagi?

Oh, there's a wood deck. The weather is nice and let's break with some tea here.

Wood deck

Nishi-san and Kita-san rested on the wood deck for a while. After leaving Ishidannoyu, they started to go up the stone steps. Next is "Ikaho Open-air Bath", which is even further ahead of the top of the stone steps. (→ Continue to Ikaho Rotenburo)

(August 2012)

Actually, Mt. Akagi is not visible from Ishidannoyu. That seems to be Mt. Komochi.

Ishidannoyu had a free tea service at this time.

Impression & rating

The quality of the hot water is reasonable. It's convenient to enjoy the hot spring water of Ikaho.

Impression & rating

It's nice to cool off after the bath on the wood deck. And, that is definitely a raccoon dog.

Gotoku-san Mizusawa Temple (Mizusawa Kanzeon)

(Photo above and below left: Main hall, below right: Hexagon hall)

Mizusawa Kanzeon is a vivid colored temple in "Mizusawa Udon Town". These days, this temple is sometimes taken up as the place with spiritual energy. Rokkakudo (Hexagon hall) is an unusual building that can be rotated the whole it. It is said that if you rotate it left three times, something good will happen to you. I thought there shouldn't be such a sweet deal, but I rotated it three times, just in case. ( Gotoku-san Mizusawa Kanzeon)
