  • The price of JR Express is "Base fare" plus "Express charge". (These are determined according to the distance.) In case of JR Express on Chuo Line, "Express charge" has two types: "Reserved seat" and "Undecided seat". Both have the same charge, which do not change depending on the season. However, the price will vary depending on where you buy. (Internet < Station < Inside the car). If you have an "Undecided seat" ticket, you can sit in any vacant seat, but you have no priority. So, if someone comes who has a "Reserved seat" ticket for the seat you are sitting, you have to give up the seat to him / her.

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.

One day in September, when the lingering summer heat doesn't seems to decline. To avoid the summer heat in Tokyo, Nishi-san and Kita-san have come to Chino City, Nagano Prefecture. Then now, the two are heading for "Togariishinoyu". They get off at Hiromi Bus Stop and are walking down the paved road where the dazzling sunlight is reflected, toward Yatsugatake.

Oops, it's hot ... I thought it would be cool here.

Exactly, this temperature is not different from Tokyo.

Are we still walking a lot?

No, it's already around here ... Oh, right at that sign.

Turn right to the gravel road at the signboard of "JOMON-U-TRA". Trees growing on both sides of the road make a good shade.

I feel relieved with this shaded road. It's a bit cool.

After all, it's very different just not being in direct sunlight.

Oh, the way down here?

Togariishinoyu signboard


... no, no! Turn right at here. There's an information board.

Oh! It's hard to find! How did you find out it? The letters are terrible too.

No, not terrible, it's unique ... maybe.

If you follow the road on the right, you will find a dead end, a building on the left and a parking lot on the right.

Parking lot side entrance of the reception building

This is ... here. There is no other building. Is this the entrance?

I think so.

Anyone is there? Don't tell me it's a day off today ...

Fortunately, it's not a day off. The open-air bath that Nishi-san and Kita-san are aiming for is located further back in the parking lot.

Togariishinoyu little path to the open-air bath

Little path to the open-air bath

It's just a trail.

I think they have the intention trying to avoid artificial things as much as possible. The Jomon period is the theme, isn't it?

I see. I'm getting a little more interesting.

I'm excited about what's ahead of this trail.

The reception building of Togariishinoyu has two entrances: A tennis court side and a parking lot side. The tennis court side is a main entrance, but the parking lot side is convenient for taking the open-air bath.

Togariishinoyu main entrance

Main entrance

After walking for some time, they saw a wall made of reeds and a banner that would indicate the entrance to the bathing room. It looks like a women's bath in the foreground and a men's bath in the back.

Togariishinoyu the path to the open-air bath

Women's bath on the left, men's bath on the back

Well, on one hand it's natural-friendly, but on the other hand it's rat-trap, you know.

At any rate, the theme is the Jomon period.

Passing through the banner, there is an undressing room like an arbor. Of course, there are no civilized tools such as coin lockers. And, an open-air bath with green cloudy water appeares in front of the forest.

Togariishinoyu open-air bath

Open-air bath

Wow, that's great!

This is exactly the taste of the open-air bath created in the old days of Jomon.

Speaking of which, every bath in the Jomon period was like this.

... Have you ever seen it?

After kakeyu (hot water for washing off before bathing), the two get into the bath immediately.

Kakeyu (hot water for washing off before bathing)

Oh, it's not so hot. I feel good this temperature in summer ... Oh! It's dangerous!

What? What happened?

Slipped. It was about to fall. The bottom of this bathtub is slimy, you know.

Right. Exactly, this must slip and fall if you're not careful.

The men's bath is in the back, the women's is in the front. They used to be a daily change for men's and women's, but now it is fixed.

Don't they clean? Is this because of Jomon too?

I can't say. But this water is greenish. Does it have a lot of iron? It's a fresh feeling and it's pretty good.

Speaking of fresh, the air here. Indeed, that's surrounded by woods, so much oxygen, you know.

Well, I feel like that. ... Oh, the water at the spout has a bit of like sulfur odor. And ... Yeah, the taste is iron or mineral-like.

And this spout will be a waterfall shower too.

Ah, you can do that.

In a cool breeze that blows through the forest, the lukewarm water is perfect for a long bath.

But it's so quiet ... Just the sound of water and the noise of trees ...

This sense of free is rare. Around the bathtub has no fences, directly a forest.

Oh! Deer!

What!? Where!?

Between those trees. For a moment, though.

Is it really a deer?

Not a size of dog, and I think that silhouette is probably a deer ...

Well, in this forest, no wonder there are deers.

Kita-san feels lucky being able to see a deer for a moment. After the deer leaves, the forest has returned to just the sound of water and the noise of trees, as if nothing had happened.

Togariishinoyu break room in Tateshina Executive House

Break room (in Tateshina Executive House)

(September 2018)

We don't know the frequency of cleaning. But according to a leaflet called "Request for bathing" of Togariishinoyu, "Since this natural hot spring with a flowing water has a strong power to revive creatures, so the algae like iwanori grows in few hours. Therefore, there may be places where the bath bottom and surrounding rocks can be slimy."

Impression & rating

Hot water with a strong presence with iron taste, mineral taste and a slight sulfur smell. It is a good hot spring that has a freshness.
