Japan is famous for its hot springs, but some of the most memorable onsen experiences are found far beyond central Tokyo.

For international travelers looking for a quieter side of Japan, Gunma and the surrounding mountain areas offer traditional ryokan, open-air baths, beautiful forests, snow-covered landscapes in winter, and peaceful towns where you can slow down for a few days.

The challenge is getting there — especially after a long international flight with suitcases.

KT Hire provides private door-to-door transportation from Narita Airport, Haneda Airport and Tokyo hotels to onsen towns and ryokan throughout the region.

And of course, we can also arrange the return journey from your onsen hotel back to Tokyo, Haneda Airport or Narita Airport.

Takaragawa Onsen — One of Gunma’s Most Famous Mountain Hot Springs

For international visitors searching for a unique Japanese onsen experience, Takaragawa Onsen (宝川温泉) is one of the names that often appears.

Located in the Minakami area of Gunma Prefecture, Takaragawa Onsen is famous for its large open-air baths surrounded by mountains and nature.

Getting there by public transportation can require several stages. The official access information from Takaragawa Onsen, for example, shows a route from Narita Airport through Tokyo, Jomo-Kogen and Minakami before reaching the onsen area.

With a private vehicle, the journey becomes much simpler:

Narita Airport → Takaragawa Onsen
Haneda Airport → Takaragawa Onsen
Tokyo Hotel → Takaragawa Onsen

And for your return:

Takaragawa Onsen → Narita Airport
Takaragawa Onsen → Haneda Airport
Takaragawa Onsen → Tokyo Hotel

Your luggage stays with you, and the vehicle takes you directly to your accommodation.

Shima Onsen — A Peaceful Alternative to Japan’s Busy Tourist Areas

Shima Onsen (四万温泉) is another beautiful destination in Gunma.

Surrounded by mountains, rivers and forests, it offers a completely different atmosphere from Tokyo. JNTO describes Shima as an onsen area that has largely avoided over-development and overcrowding, making it especially attractive for travelers looking for nature and relaxation.

Instead of changing trains and buses while carrying large suitcases, travelers can arrange a direct private transfer from their airport or Tokyo accommodation to their ryokan.

Hoshi Onsen — For Travelers Looking for Something Truly Different

Another fascinating destination is Hoshi Onsen (法師温泉) in Minakami.

It is exactly the type of place that makes a longer Japan itinerary special: quiet, traditional and surrounded by nature.

Access by public transport is possible, but services to the onsen itself are limited. Gunma’s official tourism guide explains that reaching Hoshi Onsen involves traveling through Jomo-Kogen and Sarugakyo, followed by a local bus; the official Hoshi Onsen site also notes the limited bus frequency.

For families, couples and groups traveling with luggage, a private vehicle can make this part of the journey considerably easier.

Manza Onsen — A Mountain Onsen Worth the Journey

For travelers who want to go even deeper into the mountains, there is Manza Onsen (万座温泉).

Located at around 1,800 meters above sea level, Manza offers a very different landscape and is particularly attractive during the colder months.

Its mountain location also means transportation requires more planning. The Manza Onsen tourism association gives an approximate driving time of just over three hours from Nerima IC in Tokyo, depending on the route and conditions.

This makes private transportation especially useful for travelers carrying several suitcases or traveling as a family or small group.

Minakami, Tanigawa and Ikaho — More Onsen Choices Around Gunma

Your journey does not have to stop with the best-known names.

We can also discuss transportation to destinations such as:

Minakami Onsen (水上温泉)
Tanigawa Onsen (谷川温泉)
Ikaho Onsen (伊香保温泉)

Different travelers want different experiences.

Some prefer a traditional ryokan for one night. Others spend two or three nights relaxing in the mountains before returning to Tokyo. International visitors staying in Japan for 10 days, two weeks or longer may also include an onsen stay between other destinations.

That is where flexible private transportation becomes particularly useful.

Airport → Onsen, Onsen → Airport, Tokyo → Onsen

KT Hire is not limited to one fixed route.

We can arrange transportation based on your actual Japan itinerary.

For example:

Narita Airport → Takaragawa Onsen
Haneda Airport → Shima Onsen
Tokyo → Hoshi Onsen
Tokyo → Minakami Onsen

or the reverse:

Takaragawa Onsen → Narita Airport
Shima Onsen → Haneda Airport
Minakami → Tokyo Hotel

You can also combine destinations as part of a longer private journey.

Tokyo → Onsen → Karuizawa → Tokyo

or

Tokyo → Minakami / Takaragawa → Kusatsu → Karuizawa

Tell us where you would like to go, and we can discuss a suitable route.

A Comfortable Choice When Traveling with Luggage

One of the biggest advantages of private transportation is simple: you do not have to keep moving your luggage.

After arriving at Haneda or Narita Airport, our driver meets you and takes you to the vehicle.

For airport pickups, KT Hire provides complimentary meet-and-greet service with a name board.

Depending on your group size and luggage, we can arrange an appropriate private vehicle. Child seats can also be prepared when requested in advance.

For longer journeys, we can stop at a Japanese highway Service Area so you can use the restroom, stretch your legs, have coffee or enjoy a simple meal.

Rather than treating the journey as something to endure, it can become part of your Japan experience.

Winter Onsen Transfers Need Extra Planning

Mountain onsen destinations become especially beautiful during winter.

Snow-covered ryokan, outdoor baths and quiet mountain scenery can be unforgettable.

However, winter road conditions can also affect travel times and routes. For destinations such as Manza, Takaragawa and other mountainous areas, we recommend contacting us early so that we can review your dates, passenger count, luggage and destination before confirming transportation.

Tell Us Your Ryokan — We’ll Help Plan the Transfer

You do not need to know the perfect transportation route before contacting us.

Simply send us:

• Arrival or departure airport
• Travel date
• Flight information
• Hotel or ryokan name
• Number of passengers
• Number and approximate size of suitcases
• Child seat requirements, if any
• Your next destination

We can then check the route and recommend a suitable vehicle and transportation plan.

Whether you are searching for a Narita Airport to Takaragawa Onsen private transfer, Haneda Airport to Minakami transfer, Tokyo to Shima Onsen private car, or transportation from a remote ryokan back to the airport, KT Hire can help you plan the journey.

Japan’s best experiences are not always beside a train station.

Sometimes the journey into the mountains is exactly what makes the trip unforgettable.
