The Hokkaido Shinkansen is more than just a railway line—it's a modern engineering masterpiece connecting Japan's main island with Hokkaido. Since its opening in 2016, this route has completely transformed travel to Hokkaido, turning journeys that once required ferries or airplanes into a high-speed rail experience through the seabed.
Technical Breakthroughs and Engineering Marvels
The most astonishing feature of the Hokkaido Shinkansen is the 53.85-kilometer Seikan Tunnel section, with 23.3 kilometers running beneath the sea—making it the world's longest underwater tunnel. Trains travel at 140 km/h through the tunnel, passing 140 meters below the Tsugaru Strait seabed, with the entire undersea section taking approximately 15 minutes. This project took 24 years to complete, overcoming technical challenges such as high underwater pressure and saltwater corrosion.
To cope with Hokkaido's harsh winters, the Shinkansen employs special snow prevention technology. The train cars are equipped with powerful snow removal devices underneath, while snow fences and snow-melting systems are installed along the tracks, ensuring normal operation even during heavy snowstorms. The E5 series train cars feature a "Tokiwa Green" color scheme, symbolizing Hokkaido's forests, and the Gran Class cars offer exquisite bento boxes made with local Hokkaido ingredients.
Major Stations and Nearby Attractions
Shin-Aomori Station（〒038-0003 Aomori Prefecture, Aomori City, Ishi-e, Takama 140-2）
As the northernmost Shinkansen station on the main island, this is the last stop before heading to Hokkaido. The station's "Aomori Products Plaza" sells local specialties such as Tsugaru apples and Ōma bluefin tuna. It is recommended to arrive 30 minutes before departure to taste Aomori's famous "Scallop Bento."
Okutsugaru-Imabetsu Station（〒030-1505 Aomori Prefecture, Higashitsugaru-gun, Imabetsu Town, Ōkawadaira Kiyokawa 87-16）
This is the last station before the entrance to the Seikan Tunnel on the main island side, and the platform offers views of the Tsugaru Strait. Although it is a small station, it houses the "Tsugaru Strait Memorial Museum," showcasing the tunnel's construction history. During winter, you can see the snow-covered mountains of Hokkaido across the strait from here.
Kikonai Station（〒049-0422 Hokkaido Kamiiso-gun, Kikonai Town, Honmachi 338-14）
The first station when stepping onto Hokkaido soil, and also a hub for transferring to the South Kawashiri Railway. The nearby "Michi-no-Eki Misogi no Sato Kikonai" is a great place to purchase Hokkaido seafood, with the local "Kikonai Oysters" being highly recommended—the meat is plump and affordable (approximately ¥800 for 6 pieces).
Shin-Hakodate-Hokuto Station（〒041-1201 Hokkaido Hokuto City, Shi-watari 1-chome 1-ban 1-go）
The terminal station of the Hokkaido Shinkansen, and also a transportation center for accessing Hakodate city and the southern Hokkaido area. The "Hokuto City Tourism Exchange Center" in front of the station offers free travel consultation and can arrange Hakodate night view sightseeing buses. Due to rising air freight costs, the Shinkansen has become an important channel for transporting Hokkaido seafood, and the station bento boxes here use fresh seafood delivered directly on the same day.
Hakodate City Connection
The rapid Airport train from Shin-Hakodate-Hokuto Station takes approximately 15 minutes to reach JR Hakodate Station. It is recommended to purchase the "Hakodate-Ōnuma District Pass"（¥1,580）, which allows unlimited rides on designated trains within one day, along with discounts at attractions such as the Hakodate Morning Market and Goryōkaku Tower.

Travel Tips
Seasonal Recommendations
Winter（December-March）is the best time to experience the snow country Shinkansen, but be aware of possible delays due to heavy snow. Spring（April-May）offers cheaper tickets and stable weather. Summer（June-August）is peak tourist season, and Hakodate night view sightseeing is most popular. It is recommended to use the "Hokkaido Railway Pass" 7-day pass（¥26,000）for in-depth travel planning.
Luggage Handling Tips
The luggage racks on Hokkaido Shinkansen cars are slightly smaller than those on regular Shinkansen trains. It is recommended to use soft-sided luggage. For large luggage, you can use the "Hands-Free Tourism" service, which delivers directly to Hakodate city hotels（¥500 and up, delivered next day）.
Food and Souvenirs
Due to a 30-40% increase in cold chain logistics costs, more Hokkaido seafood is now transported via Shinkansen, significantly improving the quality of station bento boxes. The "Strait Bento"（¥1,380）at Shin-Aomori Station and the "Hokkaido Seafood Chirashi"（¥1,580）at Shin-Hakodate-Hokuto Station are recommended, both made with same-day delivered ingredients.
Special Experiences
Pay attention when passing through the Seikan Tunnel—a special announcement is broadcast inside the carriages explaining that you are passing through Japan's deepest underwater tunnel. It is recommended to sit on the right side（Seats A, B）to see Hokkaido's magnificent scenery first thing after exiting the tunnel. During winter, drifting ice on the Tsugaru Strait can be seen from the windows—a rare natural spectacle.
