Karuizawa’s timeless appeal
Karuizawa is a destination that welcomes visitors year-round. Whether you’re drawn to its snowy slopes in winter, lush summer forests, or the amber-hued beauty of autumn, this mountain town offers a refreshing break from urban life.
Sitting at an elevation of around 1,000 meters (3,280 feet), Karuizawa was first embraced by foreign residents in the late 19th century and has since evolved into a vibrant hub for seasonal activities. From hiking, cycling, and golf in the warmer months to skiing and ice skating in winter, the town offers something for every traveler. It is also easily accessible from Tokyo, with the Hokuriku Shinkansen railway line making the journey in just over an hour.
How to get to Karuizawa
Choosing the right mode of transport can make all the difference in how you start your trip. It ensures you arrive relaxed and ready to enjoy everything Karuizawa has to offer.
There are three main ways to travel from Tokyo to Karuizawa: by Shinkansen, bus, or car. The best option depends on your budget, travel style, and priorities.
If you love soaking in every moment of the journey, enjoying scenic routes, and immersing yourself in local experiences, one traveling option might suit you better. If you’re traveling with family and prefer comfort and speed, another might be ideal. And if you’re on a solo trip, balancing budget and convenience, there’s a way to make it work without compromising on either.
No matter how you choose to get there, once you arrive in Karuizawa, you are guaranteed to be surrounded by breathtaking beauty. Here’s a closer look at each option to help you make the best choice for a smooth and stress-free journey.

Designed for speed and efficiency, The Hokuriku Shinkansen railway line offers a speedy connection between the capital and some of Japan’s most scenic and culturally rich areas.
The Shinkansen connects Tokyo Station to Karuizawa Station in approximately an hour and a half.
The Hokuriku Shinkansen starts its journey at Tokyo Station and then moves to Ueno and Omiya. From there, it passes through Kumagaya, Honjo-Waseda, Takasaki, and Annaka-Haruna before finally arriving in Karuizawa.
With the Japan Rail Pass, travelers have the option to choose between standard seating or the more premium Green Car seating.
Japan Rail Pass explained
The Japan Rail Pass, often referred to as the JR Pass is a special ticket designed for foreign visitors traveling long distances across Japan. It allows unlimited travel on JR trains for a duration of one, two, or three weeks. The Japan Rail Pass comes in two options – Ordinary and Green Car.
Green Car vs. Ordinary
Green Car and Ordinary offer different levels of comfort for travelers. Green Car provides more spacious seating, extra legroom, and a quieter atmosphere. This makes it a great option for families looking for a stress-free journey or business travelers who want a comfortable and quiet space to prepare for their meetings. These premium seats are available on most Shinkansen and limited express trains, as well as a few local trains.
The Green Car pass became more expensive after a price increase in late 2023, but it remains a good choice for travelers who value convenience and unlimited train travel without the hassle of purchasing separate tickets.
On the other hand, ordinary seats are a more budget-friendly choice. If you’re a solo traveler or don’t mind a livelier atmosphere with a bit less space, the ordinary car provides a perfectly comfortable and cost-effective way to enjoy the journey.
| Type | Green Car (Yen) | Ordinary (Yen) |
|---|---|---|
| 7 days (Consecutive) | 50,000 | 70,000 |
| 14 days (Consecutive) | 80,000 | 110,000 |
| 21 days (Consecutive) | 100,000 | 140,000 |
If you’re traveling with children, there’s good news—children aged 6 to 11 can ride for half the price. This makes it easier for families to explore without stretching the budget.
Is a bus your best bet for an affordable trip to Karuizawa?

If you are looking for a budget-friendly way to reach Karuizawa, taking the highway bus is a great option. With five trips running daily between Tokyo and Karuizawa, you have plenty of chances to plan your journey at a convenient time.
The bus ride takes about 3 hours, giving you a chance to sit back, relax, and enjoy the passing scenery. Ticket prices range from 2,300 to 2,900 JPY, depending on the day you travel.
You can book your seat in advance through its online reservation platform to avoid last-minute stress.
With direct departures from major stations, it is a hassle-free way to reach the destination without switching trains or worrying about complicated transfers. This is especially useful for foreign travelers, as navigating different train lines can be tricky when faced with a language barrier.
Many long-distance buses also provide reclining seats and onboard restrooms, ensuring a more comfortable ride. If you’re carrying bulky luggage, most buses have spacious storage compartments, so you won’t have to struggle with overhead racks.
That said, taking the bus does require more patience. The journey takes over three times longer than the Shinkansen, and traffic conditions can sometimes lead to delays. Since there are fewer departures compared to trains, flexibility is a bit limited as well. For those who don’t mind a slower pace, the bus remains a practical and cost-effective way to reach Karuizawa.
Reaching Karuizawa’s must-see spots with ease
If your destination is a bit farther from JR Karuizawa Station, hopping on a local bus is an easy way to get there.
Renting a bike is another fantastic option if you want to travel on your own schedule. You’ll find plenty of rental shops near Karuizawa Station, making it easy to grab one and discover the town’s charming streets.
Just a heads-up—parking in front of shops and cafés on Old Karuizawa Ginza Street isn’t allowed, so be sure to use the free bicycle parking areas nearby.
If you prefer a more private mode of transport, taxis are an option. However, they tend to be pricey, so unless you’re short on time or need a more direct route, they may not be the best choice for getting around.
Is driving the most flexible option?
With a car, you can take detours and enjoy the scenic countryside along the way. The drive takes around 2.5 to 3 hours, following the Kanetsu Expressway and National Route 18, making for a smooth and enjoyable road trip.
If you’re traveling with friends or family instead of going solo, renting a car can be a smart choice. Splitting the rental cost and fuel can make the rented car a budget-friendly option.
Plus, having a car allows easy access to beautiful spots outside the main town, like Onioshidashi Park or the stunning Shiraito Falls.
Onioshidashi Park
Onioshidashi Park is a striking natural wonder shaped by the powerful eruption of Mount Asama in 1783. The park has an almost otherworldly scene with volcanic rocks stretching across the terrain. Though technically located in Gunma Prefecture, it’s a popular stop for those visiting Karuizawa.
Beyond its dramatic rock formations, the park offers panoramic views of the surrounding countryside and Mount Asama on clear days. At the center of the park, you’ll find a peaceful temple dedicated to Kannon, the Buddhist Goddess of Mercy. Kids will enjoy wandering through the unique rock formations, while adults can take in the cultural and historical importance of the site.
Shiraito Falls
Just a short drive from Karuizawa, Shiraito Falls is a spot known for its delicate streams of water cascading over the rock face. Unlike powerful waterfalls, this one creates a curtain-like effect, earning its name “White Thread Falls.”
Stretching about 150 meters wide and standing 20 meters tall, it offers a peaceful escape into nature. The scenery is beautiful year-round, but autumn is especially enchanting when the surrounding leaves turn brilliant shades of red and gold.
Things to keep in mind before renting a car
Driving comes with a few extra costs. Expressway tolls can range from 4,000 to 5,000 JPY, and fuel expenses depend on your route. Some hotels and tourist spots also charge for parking. Traffic can be another downside, especially during peak seasons when congestion may slow things down.
