What is the Seikan Ferry? 80 years of supporting the flow of people and goods between Honshu and Hokkaido [Aomori Prefecture]

Currently, you can travel between Aomori Prefecture and Hokkaido by plane or the Hokkaido Shinkansen, which passes through the Seikan Tunnel.
However, in the days before the Seikan Tunnel and airplanes, the only way to get between the two is by boat.
This time, we will introduce one of these boats, the unique Seikan Ferry


What is the Seikan Ferry?

The Seikan Ferry was a rail ferry that operated on
the Seikan Route , connecting Aomori Station in Aomori City, Aomori Prefecture, and Hakodate Station in Hakodate City, Hokkaido The route was 61 nautical miles (112.972 km).
In 1988, the Seikan Tunnel, an undersea rail tunnel connecting Aomori Prefecture and Hokkaido, was opened, and the Seikan Ferry ceased operation.

Ferries still operate between Aomori Port and Hakodate Port, but there are two main differences between the two

  • The ship was operated by "railway operators" such as the Japanese National Railways and JR Hokkaido, and was considered part of the railway line.
  • The ship had rail cars on board .

The Seikan Tunnel is a railway tunnel only, and cars cannot pass through it .
Therefore , even now, if you want to travel between Honshu and Hokkaido by car, you have to take your car on a ferry.


Start of operation as a national route

A sea route connecting Hokkaido and Aomori Prefecture has existed since the Edo period.
Then, on March 7, 1908 the Hirafu Maru, a ferry connecting Aomori Port and Hakodate Port, began operation under
the Imperial Railway Administration This marked the beginning of the Seikan Ferry.
The journey took about four to five hours.

Abe no
Hirafu , who appears in the Nihon Shoki, which was compiled in 720 AD He was a man who dispatched troops to Hokkaido under the orders of Emperor Saimei, and it is said that this was the first time that a voyage to Hokkaido was recorded in Japanese history.

The Seikan Ferry was a type of
railway ferry A railway ferry is a ship that operates in place of a railway in areas where it is difficult to build a railway due to the presence of seas, lakes, or rivers.

Currently, the only railway ferry operated by JR is one that goes to Miyajima in Hiroshima Prefecture, but in the past, in addition to the Seikan Ferry, there were also ferries that allowed transfers from national railway lines between Honshu and Shikoku, the Kanmon Strait between Honshu and Kyushu, Lake Biwa, Hokkaido and Sakhalin, and Shimonoseki and Busan

Just as the Seikan Ferry was started by the Imperial Railway Agency, railway ferries were primarily operated by railway operators. Not only were
fares calculated as if they were part of a railway line (you could even board the ferry with the "Seishun 18 Ticket," which allowed unlimited rides on JNR local trains), but the station platform was directly connected to the pier where you boarded the ferry, so you could transfer from the train that arrived at the station to the ferry without leaving the ticket gate. It was a ferry that you could ride just like a train

Vehicle transportation begins

A bridge for loading vehicles onto the Seikan Ferry

As the development of Hokkaido got underway in earnest, there was a need to increase the transport capacity of the Seikan Ferry,
and so in 1924 Maru a vehicle ferry capable of directly loading railroad cars such as freight train wagons, was introduced.

Actual shipping of vehicles began the following year, in August 1925.
By being able to load freight cars carried by freight trains directly onto ships, loading time was significantly reduced , and Hokkaido seafood could now be transported to Honshu while maintaining its freshness.
(In the days when the freight was transferred by hand, it was said that cargo sometimes even had to be dropped into the sea.)


war damage

During the war, the Seikan Ferry mainly served to transport coal from Hokkaido to Honshu.
On July 14, 1945, towards the end of the war, 11 of the 12 Seikan Ferries were attacked
by US Navy aircraft 352 people were killed on that day alone.
The next day, the remaining ferry sank, and four passenger ships and six cargo ships were lost.

Air raids were also carried out in August, and the Seikan Ferry was almost completely destroyed.
A monument commemorating the war damage has been erected near the Seikan Ferry "Hakkoda Maru," which is preserved in Aomori Port.

Five ships sunk in the Toya Maru typhoon

Typhoon No. 15 hit Hokkaido on September 26th causing damage by sinking five Seikan Ferries.
One of the five ships the Toya Maru , and the sinking of this ship alone claimed the lives of 1,151 people, and Typhoon No. 15 was later named the "Toya Maru Typhoon."

This maritime disaster, which claimed the lives of 1,430 people aboard the Toya Maru and four other cargo ships, is considered one of the five major postwar accidents of the Japanese National Railways.
The accident led to the realization of plans for the Seikan Tunnel .


Transportation volume begins to decline

, which connected the flow of people and goods between Honshu and Hokkaido throughout the pre-war and post-war periods, saw its cargo volume peak in 1971 and passenger volume in 1973 .

The subsequent decline in transport volume was likely due in large part to the shift from passenger transport to airplanes and freight transport to loading trucks onto ferries. Fewer people were willing to take the train
to Aomori Station and board the Seikan Ferry to Hokkaido, as described in the lyrics of Sayuri Ishikawa's hit song, "Tsugaru Kaikyo Fuyugeshiki."

The decline in freight volume continued unabated, and with construction of the Seikan Tunnel already underway, the fate of the Seikan Ferry was clear

Nevertheless, in order to improve the image of the Seikan Ferry, the Japanese National Railways (JNR) tried to improve the ferry by installing a coffee shop, an entertainment room and luxurious seats in 1978. It is said that this was the most luxurious vehicle in the JNR fleet


The role will be taken over by the Seikan Tunnel

At the time of the last timetable revision of the Japanese National Railways in November 1986, the Seikan Ferry operated seven round trips per day, with the journey time between Aomori and Hakodate being 3 hours 50 minutes or 3 hours 55 minutes

In 1987, the Japanese National Railways was split up and privatized, and the operation of the Seikan Ferry was taken over by JR Hokkaido.
The following year, 1988 , the Seikan Tunnel opened, and the Seikan Ferry was discontinued. With this,
came to an end after 80 years of service, having carried 161 million passengers and 247 million tons of cargo .

The Kaikyo rapid train, which began operating at the same time as the Seikan Tunnel opened, connects Aomori Station and Hakodate Station in around two and a half to two hours and 50 minutes, making
it possible to travel between the two stations in less time than the Seikan Ferry.In addition to the Kaikyo, other trains such as the luxury sleeper express Hokutosei (Ueno to Sapporo), the sleeper express Nihonkai (Osaka to Hakodate), the overnight express Hamanasu (Aomori to Sapporo), and the express Hatsukari (Morioka to Hakodate) began to use the Seikan Tunnel to connect cities on Honshu and Hokkaido.

These trains were all discontinued by the time the Hokkaido Shinkansen opened in March 2016, and now the Hokkaido Shinkansen's Hayabusa and Hayate trains pass through the Seikan Tunnel.

In addition, freight transport has become less susceptible to weather as the route has changed from sea to undersea tunnel.
the stabilization of logistics in Hokkaido is the greatest benefit of the opening of the Seikan Tunnel.


Hakkoda Maru and Mashu Maru

Seikan Ferry Memorial Ship Hakkoda Maru

The Seikan Ferry has been discontinued, but the Hakkoda Maru, which operated as a ferry, is preserved as the "Seikan Ferry Memorial Ship Hakkoda Maru," a five-minute walk from Aomori Station .

You can go inside (for a fee) and, of course, walk on the deck, but you can also touch the rudder and communication equipment in the wheelhouse, which passengers were not allowed to enter when the ship was in operation, and view the rail cars on board .
However, please note that the observation plaza and chimney observation deck are closed during bad weather and in winter.

The Mashu Maru, another Seikan Ferry, is preserved near Hakodate Station, and you can also tour the interior of the ship.
37 years have passed since the Seikan Ferry was discontinued, but the history of the ferry is still being passed down in both Aomori and Hakodate .
