Welcome to Japan, for the 109th Time!
Hello to everyone planning your 109th trip to Japan!
You may already be familiar with the name Karuizawa—one of Japan’s most famous resort towns.
Located in northeastern Nagano Prefecture, near the border with Gunma, Karuizawa is known for its stunning views of Mt. Asama, elegant townscape, and refreshing highland climate.
It’s also easy to reach, just one hour from Tokyo by bullet train, making it a popular getaway for both Japanese and international travelers.
Now, imagine a quiet mountain village just one hour away by car from Karuizawa, yet almost untouched by tourism.
That’s Aoki Village.
It may not be widely known, but Aoki is home to two incredible hot springs that are beloved by Japan’s onsen enthusiasts.
This village offers a completely different side of Japan—peaceful, authentic, and free from the crowds.
If you’re feeling worn out by overly polished tourist spots,
this article will show you why Aoki Village might be exactly what you’ve been looking for.
Let’s dive in—and discover this hidden gem together.
Soak Like a Local: Aoki’s Hidden Hot Spring Gems
Aoki Village is home to two small, off-the-radar hot spring areas.
They may not have the glitz and glamour of famous spots like Yufuin or Hakone, but these onsens are beloved by locals as everyday places to unwind and relax.
What they lack in luxury, they more than make up for in authentic charm and healing waters.
Let’s take a closer look at these special hot springs—quiet, humble, and full of local spirit.
Tazawa Onsen: A Timeless Hot Spring with a Story to Tell
Tazawa Onsen is said to have been discovered over 1,300 years ago, making it one of the most historic hot springs in Nagano.
Locals call it the “Hot Spring of Fertility.”
People believe the waters help with conception and even improve breast milk flow for new mothers.
As you approach the onsen town, you’ll notice a distinct sulfur smell—similar to boiled eggs.
For many Japanese, it’s a comforting scent that means the water is truly rich and natural.
But for first-time visitors, it might take a little getting used to.
The spring water is a soothing 41°C (about 105°F)—a perfect temperature to relax without overheating.
It’s just right for long, peaceful soaks.
There are a few inns (ryokan) in the area, and some offer day-use bathing.
But if you want to try the onsen like the locals do, we recommend the public bathhouse “Uchiyu” (有乳湯).
Though the bath is smal, there’s enough room for adults to stretch out comfortably.
The water flows over the edge of the tub, showing it’s a true kakenagashi (free-flowing hot spring).
It’s a simple, quiet place where you can truly feel at home—like a resident, not just a visitor.

How to Get to Tazawa Onsen
Unfortunately, public buses to Tazawa Onsen are very limited—they usually only run early in the morning and late in the evening.
Because of this, using local buses can be difficult for most international travelers.
🚗 Recommended Option
If you’d like to visit Tazawa Onsen, we strongly suggest renting a car from nearby cities like Ueda or Karuizawa.
The roads are scenic and easy to drive, and having your own vehicle makes it much easier to explore rural areas like Aoki Village at your own pace.
Kutsukake Onsen: A Quiet Retreat Deep in the Mountains
Kutsukake Onsen is a small, peaceful hot spring area tucked away in the southern mountains of Aoki Village.
It’s so quiet and hidden that even many Japanese travelers haven’t heard of it.
This makes it a true secret onsen—perfect for those seeking calm and solitude far from the crowds.
There are just a few inns and one small public bathhouse, so the area feels relaxed and uncrowded.
If you want to experience hot spring bathing in its most simple and natural form, Kuzukake is an excellent choice.
The bathhouse is called Ogura-no-Yu (小倉乃湯), and it’s open to everyone, including first-time visitors from abroad.
Unlike Tazawa Onsen, the sulfur smell here is very mild, because the bath uses two different natural spring sources.
The facilities are modest—just like the community it serves.
The space is small, but that’s part of the charm.
You’ll be close to the locals—sometimes physically!
This might feel unusual if you’re used to more personal space, but it’s a chance to connect with real local culture.
People in Aoki Village are incredibly kind.
Even if you don’t speak Japanese, a little effort and a smile will take you far.
If you’re feeling adventurous, give Kuzukake Onsen a try—you won’t regret it.

How to Get to Kuzukake Onsen
Just like Tazawa Onsen, public buses to Kuzukake Onsen are very limited.
They usually run only in the early morning and late evening, which can be difficult for travelers to use.

A little respect and awareness go a long way.
