With roughly one month to go until Japan’s iconic bullet train enters the northern island of Hokkaido for the fist time, here’s an important travel advisory for potential visitors to Hokkaido.
Between March 22 and 25, train services from the Japanese mainland to Hokkaido will be shut down in order to make final preparations for bullet train services. This means that during this four-day period, the only way to travel into and out of Hokkaido is by airplane, or by ferry to one of the northernmost ports in Honshu (i.e. Aomori).
The Seikan Tunnel is the long, 33 1/2 mile tunnel connecting Hokkaido with the Japanese mainland under the Tsugaru Strait. Since 1988, passenger trains have made the journey through this tunnel on journeys to and from the southern Hokkaido city of Hakodate. Considering the amount of freight traffic that also uses the tunnel, the Seikan Tunnel is one of the country’s most vital transportation links.
During the four day period that the tunnel is closed, construction crews will make final preparations for the introduction of the new shinkansen services. One of these steps is to raise the overhead voltage into the tunnel from 20 kV to the shinkansen standard of 25 kV.
When the Seikan Tunnel opens to Shinkansen traffic on 26 March, the vital freight services will resume operation. Naturally, JR is on top of things – two years ago, it introduced a new electric locomotive, the EH800, capable of operating at both 20 kV and 25 kV. It will be the sole locomotive hauling freight through the tunnel moving forward.
The opening of the Shinkansen stands to revitalize Hakodate – and in turn, Hokkaido – with new visitors. In the meantime, if you are planning a trip to Japan in the next month, please take note of these dates when the Seikan Tunnel will be closed.
