Looking for an onsen near Tokyo where you can escape the crowds and experience a quieter side of Japan?
About three hours from Tokyo, Shima Onsen is a small hot spring town tucked away in the mountains of Gunma Prefecture. With its rivers, forests, traditional ryokan, and peaceful streets, it offers a very different experience from Japan’s busiest sightseeing destinations.
For centuries, people have visited Shima Onsen for toji, the Japanese tradition of staying at a hot spring to rest and restore one’s health. Even today, the town retains much of that unhurried atmosphere.
There are many famous hot spring destinations within reach of Tokyo. But if you are looking for somewhere quiet, traditional, and surrounded by nature, Shima Onsen deserves a closer look.

Why Do Tokyo Hotel Concierges Recommend Hakone?
Some years ago, I visited several luxury hotels in Tokyo to introduce Shima Onsen to their concierge teams.
I asked a simple question: When your international guests ask you to recommend an onsen destination, where do you usually suggest?
Almost everyone answered: Hakone.
That was understandable. Hakone is famous, relatively easy to reach from Tokyo, and offers beautiful scenery, museums, and a wide choice of accommodation.
What surprised me was that approximately 60% of the concierges I spoke with had never heard of Shima Onsen.
It made me realize something: many international travelers may be choosing from only a small number of well-known onsen destinations, simply because they have not heard about the alternatives.
Looking for an Onsen Town Near Tokyo? There Are More Choices Than You Might Think
Japan has thousands of hot springs and a remarkable variety of hot spring destinations.
When searching for an onsen town near Tokyo, you will probably come across names such as Hakone, Kusatsu, Ikaho, and the Izu Peninsula.
Each has its own attractions. Hakone is known for its scenery and sightseeing opportunities. Kusatsu is celebrated for its abundant hot spring water and lively traditional town center. Ikaho is famous for its stone steps, while Izu offers coastal landscapes as well as mountain retreats.
These are popular destinations for good reasons. Kusatsu, for example, welcomes millions of visitors annually.
But popularity is not necessarily what every traveler wants.
Some visitors enjoy lively streets, famous landmarks, and plenty of things to do. Others are looking for a small town where they can walk beside a river, soak in a hot spring, and enjoy the feeling of being far away from the rush of everyday life.
For the second group, Shima Onsen may be just the right place.
Shima Onsen: A Quiet Onsen Town Near Tokyo, Rural but Not Remote
Shima Onsen is located in a mountain valley in northwestern Gunma Prefecture.
It is a rural destination, but not an isolated wilderness. There are traditional inns, small shops, cafes, local roads, and buses connecting the town with the railway network.
What makes Shima special is the balance between an established hot spring town and the natural landscape surrounding it.
Walk through the town and you will find old-fashioned buildings, narrow streets, and a pace of life that feels different from Tokyo. There is no need to rush from one attraction to the next.
The Shima River runs through the valley, and the surrounding mountains change with the seasons. In spring, fresh greenery fills the landscape. Summer brings deep green forests, autumn colors the hillsides, and winter offers the pleasure of soaking in hot water in the cold mountain air.
The area is also known for the distinctive blue-green color of its water, often called Shima Blue.
Shima Onsen is not completely unknown in Japan. It appears in domestic hot spring rankings and has long been appreciated by Japanese travelers. Yet it remains relatively unfamiliar to many visitors from overseas.
That is part of its appeal: a genuine Japanese hot spring town that is accessible from Tokyo without feeling like an extension of the city’s tourist circuit.
Who Would Enjoy Staying in Shima Onsen?
I particularly recommend Shima Onsen to travelers who:
- Want to escape busy sightseeing areas and spend time somewhere peaceful.
- Are interested in experiencing everyday life in the Japanese countryside.
- Love hot springs and want to enjoy bathing as an experience in itself.
- Are visiting Japan for the second or third time and want to discover somewhere new.
- Would like to slow down toward the end of their trip before returning home.
You do not need an elaborate sightseeing itinerary here.
Take a walk, stop for coffee, listen to the river, enjoy a long bath, and settle into a traditional Japanese inn.
Sometimes the most memorable part of a trip is having time to do very little.
Why Do International Travelers Choose Shima Onsen?
I have lived in the Shima Onsen area for more than 40 years, and I also guide walking and cycling tours for visitors.
During these tours, I often ask international guests a question:
“Why did you choose Shima Onsen?”
Their answers are interesting.
Some tell me they were looking for a quiet onsen town away from crowded tourist destinations.
Others say they were drawn to the nostalgic atmosphere of Shima Onsen, particularly the historic Sekizenkan building and its red bridge, which remind them of scenes from the animated film Spirited Away.
Shima Onsen is not officially identified as the setting of the film, but I understand why visitors make the connection. There is something about the old buildings, mountain surroundings, and evening lights that captures the imagination.
And some guests give me a very simple answer:
“We wanted to stay at Kashiwaya Ryokan.”
For me, that is especially encouraging. It means that travelers are discovering not only a destination but also a particular kind of Japanese hospitality.
Why Stay at Kashiwaya Ryokan in Shima Onsen?
Kashiwaya Ryokan is a small, independently operated Japanese inn with just 14 guest rooms, all overlooking the river.
We welcome travelers who want to enjoy traditional Japanese accommodation, hot springs, local food, and a relaxed atmosphere.
Our goal is not to provide a long list of activities. It is to offer a comfortable place where you can slow down and experience the pleasures of staying at an onsen ryokan.
Three Free Private Outdoor Onsen Baths
One of the distinctive features of Kashiwaya Ryokan is our three private outdoor onsen baths.
All three are available to staying guests free of charge, without advance reservations. You can use an available bath privately by locking the door from the inside.
This is particularly convenient for couples, first-time onsen visitors, and guests who prefer bathing in private.
Tattoo-Friendly Onsen
At Kashiwaya Ryokan, tattoos are welcome in all our baths, including the shared public baths and the three private outdoor baths.
There is no need to cover your tattoos.
We want guests to feel comfortable enjoying Japanese hot spring culture without unnecessary worries.
Traditional Japanese Meals and Vegan Options
Another important part of a ryokan stay is the food.
At Kashiwaya Ryokan, dinner and breakfast are served in our dining area. Our meals introduce guests to Japanese flavors, seasonal ingredients, and the pleasure of taking time over a meal.
We can also prepare vegan meals for parties of two or more with advance arrangements. Please contact us before booking if you have dietary requirements, as some restrictions cannot be accommodated.
A Small Ryokan with English-Speaking Staff
Staying at a traditional ryokan can be unfamiliar, especially on your first visit to Japan.
Our English-speaking staff are happy to explain how to enjoy the baths, what to expect at mealtimes, and how to make the most of your stay.
Because we are a small inn, we value personal connections with our guests.
For information about rooms, baths, meals, and reservations, please visit the Kashiwaya Ryokan official website.
How to Get to Shima Onsen from Tokyo
Although Shima Onsen feels far removed from the city, it is quite accessible. Depending on your route and connections, the journey from Tokyo generally takes around three hours, sometimes longer.
There are several ways to get here.
1. Direct Highway Bus from Tokyo Station
The Shima Onsen Go highway bus offers a convenient direct connection from Tokyo Station to Shima Onsen.
It normally departs in the morning, making it possible to travel without changing trains or buses.
This is a particularly straightforward option if you prefer not to manage railway transfers with luggage.
Check the latest timetable and operating dates before traveling.
2. Limited Express Train from Ueno to Nakanojo
Take the Limited Express Kusatsu-Shima from Ueno Station to Nakanojo Station.
From Nakanojo, continue by local bus to Shima Onsen.
This is a popular route for travelers who enjoy rail journeys and want to see the scenery change as they leave the Tokyo metropolitan area.
3. Shinkansen via Takasaki
Another option is to take a Shinkansen from Tokyo to Takasaki, transfer to the JR Agatsuma Line, and travel to Nakanojo Station.
From there, take the local bus to Shima Onsen.
This route offers flexibility, although the total journey time depends on train and bus connections.
4. Shinkansen to Jomo-Kogen and a Rental Car
If you prefer to drive through the countryside, you can take the Shinkansen from Tokyo to Jomo-Kogen Station and rent a car there.
For example, a Shinkansen journey of approximately 63 minutes followed by a drive of around 53 minutes gives a combined travel time of just under two hours.
Allow additional time for train connections, collecting the rental car, and any stops along the way.
A rental car also gives you the freedom to explore the surrounding mountains and villages at your own pace.
Whichever route you choose, please check current transportation schedules before departure.
Perhaps the Best Onsen Near Tokyo for You Isn’t the Most Famous One
Hakone, Kusatsu, Ikaho, and other famous hot spring destinations have much to offer. I would never suggest that one is universally better than another.
But different travelers are looking for different experiences.
If your ideal visit to Japan includes a peaceful mountain town, a traditional ryokan, quiet streets, beautiful rivers, and plenty of time to enjoy the hot springs, Shima Onsen might be exactly what you are looking for.
It may not be the first name you encounter when searching for an onsen near Tokyo.
But sometimes the places you remember most are the ones you had never heard of before.
We look forward to welcoming you to Shima Onsen.
