Tokyo to Sapporo: Shinkansen Through the Seikan Tunnel, Services and Winter Notes

On a platform at Tokyo Station, the long white nose of a Hayabusa slides in, and somewhere in the crowd a traveler is already thinking about miso ramen and a mug of cold Sapporo beer far to the north. The question comes up whenever a Japan itinerary stretches toward Hokkaido. The rail answer is a single Shinkansen ride from Tokyo that crosses under the sea through the Seikan Tunnel and ends at Shin-Hakodate-Hokuto, with the airports of Haneda and Narita as the other way to begin the trip.

How do you get from Tokyo to Sapporo?

You go north by Shinkansen, the high-speed train that leaves Tokyo on the Tohoku Shinkansen and continues onto the Hokkaido Shinkansen, the line run by JR Hokkaido that links Aomori Prefecture on Honshu with Hokkaido through the Seikan Tunnel. The Hayabusa express is the train that runs straight through from Tokyo to Shin-Hakodate-Hokuto, so there is no change of train between the capital and the island.

The fastest journey between Tokyo and Shin-Hakodate-Hokuto is currently 3 hours, 57 minutes. That is the train’s own timing, and it is where the Shinkansen part of the trip ends. Sapporo is a separate stretch of Hokkaido beyond that terminus, and the rest of the way is a matter of planning your own continuation once you are on the island.

The Tohoku Shinkansen from Tokyo

The first leg runs on the Tohoku Shinkansen, Japan’s longest Shinkansen line. Four services run on it: the express Hayabusa, the limited-stop Yamabiko, and the all-stop Hayate and Nasuno. For a trip to Hokkaido, the one to look for is the Hayabusa.

The line has a fast stretch between Utsunomiya and Morioka, where trains reach the highest operating speed on the route. Passengers feel it as a smooth, quiet glide past rice fields and river valleys, with the Tokyo skyline giving way to farmland and then to forested hills. JR East has announced plans to raise top speeds further after 2030, depending on noise and vibration technology.

Crossing into Hokkaido

At Shin-Aomori the Tohoku Shinkansen meets the Hokkaido Shinkansen, which opened on 26 March 2016 between Shin-Aomori and Shin-Hakodate-Hokuto. The through Hayabusa trains simply carry on, and the crossing under the strait is the moment the journey changes character, with the train entering the Seikan Tunnel on Honshu and coming out on the island of Hokkaido.

Through the tunnel section the track is shared with narrow-gauge freight trains, so Shinkansen speeds are held down there. The shock wave from a Shinkansen at full speed could unsettle a freight train passing in the opposite direction. During holiday periods JR Hokkaido raises the limit through that section, which trims the journey time on those days.

Flying as the other option

Tokyo has two airports, Haneda, officially Tokyo International Airport, and Narita, Japan’s largest international airport. A trip to Sapporo by air starts from one of them. The choice often follows where you are staying in the city and where an earlier flight landed, and it changes how the day begins: a Shinkansen departs from a central station, while an airport day starts with the ride out to the terminal.

Which options are there?

There are two broad ways to cover the distance: the Shinkansen to Hokkaido, with the Hayabusa as the through train, or a flight from one of Tokyo’s two airports. Within the rail option, the services on the Hokkaido Shinkansen differ in how far they run and where they start.

Hayabusa and Hayate on the Hokkaido Shinkansen

Two types of train serve the Hokkaido Shinkansen. The express Hayabusa runs between Shin-Hakodate-Hokuto and Shin-Aomori, with through services to Tokyo or Sendai. The local Hayate runs between the same two stations, and some of its trains continue to Morioka. Only the Hayabusa through services carry you from Tokyo without changing.

All services are formed of 10-car E5 trainsets from JR East or H5 trainsets from JR Hokkaido, so the train you board looks much the same whichever company owns it.

Service Runs between Daily round trips (initial timetable)
Hayabusa Tokyo and Shin-Hakodate-Hokuto Ten
Hayabusa Sendai and Shin-Hakodate-Hokuto One
Hayate Morioka and Shin-Hakodate-Hokuto One
Hayate Shin-Aomori and Shin-Hakodate-Hokuto One

The lines side by side

The two Shinkansen lines you use are very different in scale. One is a long trunk line from the capital, the other a short extension that carries the train under the sea and onto Hokkaido.

Line Operator or role Length (km)
Tohoku Shinkansen Japan’s longest Shinkansen line 674.9
Hokkaido Shinkansen JR Hokkaido, Shin-Aomori to Shin-Hakodate-Hokuto 148.8

Branches that share the track

You may notice other names on the departure boards at Tokyo Station. The Tohoku Shinkansen has two mini-Shinkansen branches, the Yamagata Shinkansen and the Akita Shinkansen, which run at conventional speeds on widened track so that Shinkansen trainsets can run through. Komachi trains to Akita are typically coupled to Hayabusa trains between Tokyo and Morioka. Tsubasa trains to Shinjo are typically coupled to Yamabiko trains between Tokyo and Fukushima.

This matters at the platform, because a coupled train carries cars for different destinations. The Hayabusa for Hokkaido is the service to watch for, and the coupling simply means that the front or rear cars may split off partway along the line while the rest continue north.

Tokyo’s own rail network

Getting to the Shinkansen platforms is a small journey in itself. In Tokyo you will find Japan Railways trains, Tokyo Metro lines and Toei Subway lines, among others. Local trains stop at every station, while rapid trains skip smaller stations and do not require a supplement. Japanese trains have a reputation for always being on time, which lets travelers plan the connection to the minute.

What should you know before you travel from Tokyo to Sapporo?

Know that the Shinkansen ends at Shin-Hakodate-Hokuto, not in Sapporo, and that winter changes the way the trains run. Beyond that, a few details of the line and of Hokkaido itself help you picture what you are heading toward.

Winter on the line

Snow is part of the story on this route. On Hokkaido Shinkansen trains running at speed, snow can build up in the bogies, the wheel assemblies underneath, up to 3 cm by the time a train reaches a station. It can cause damage or schedule delays. The same trains look nearly empty in the coldest weeks, since the line’s occupancy rate fell to a low of 19% in January and February.

None of that stops the season from being a draw. The Sapporo Snow Festival is held annually in February, and snow shapes the whole feel of Hokkaido in winter, from the skiing and trekking to the steam rising off hot springs. A winter trip simply asks for a little patience with the timetable.

What waits in Sapporo

Hokkaido is the northernmost island of Japan and the second largest. It draws travelers with seasonal views, outdoor activities such as skiing and trekking, Ainu and Jomon culture, gourmet food and hot springs. Sapporo sits at the center of that picture, and it hosted the first Winter Olympic Games in Asia in 1972.

The city is also a place to eat and drink. At the Sapporo Beer Museum and its pub, the Sapporo Beer Garden, visitors can enjoy a beer with a lamb barbecue, a pairing of malty brew and sizzling meat that suits a cold northern evening. Travelers plan their whole first night around it.

The Tokyo end of the trip

Tokyo is the capital of Japan and the most populous metropolitan area in the world. It lies on Tokyo Bay, in the Kanto region on Honshu, the largest island of Japan. If you have a morning free before the train, Ginza offers high-end restaurants and luxury shops, while Nihonbashi is known for its rich heritage and is the main financial district of Japan.

Both districts lie in the same city as the departure station, so they make a way to spend the hours before a departure with something to look at, whether that is a department-store food hall or a stroll past old bridges and bank buildings.

Roads, signs and driving

If your plans on Hokkaido involve a car, remember that traffic in Japan moves on the left side of the road.

Good to know before you go

Leave room in a winter itinerary for snow to slow a train, since the line is one that feels the season. The trip rewards a traveler who thinks of it as a day on the rails with a long stretch of Hokkaido beyond the last Shinkansen station. Once you arrive, the city’s pleasures are simple ones: the lamb barbecue at the beer garden, the snow sculptures of February, and the island’s hot springs afterward.
