Hokkaido, formerly known as Ezo, is the second largest island of Japan and locates at the northernmost
of its 47 prefectures. The Tsugaru Strait separates Hokkaido from Honshu, although the two islands are
connected by the underwater SeikanTunnel. The capital is Sapporo, the most populated city in Hokkaido,
that is about 1,890,000.

The Hokkaido Railway Company is one of the constituent companies of Japan Railways Group, and
thus often known as JR-Hokkaido. It operates inter-city-rail services in Hokkaido. A privatization from
Government-owned railway is carried out in 1987. The length of railway tracks operated at that time
was over 3,000 km. This has dwindled to below 2,500 km, as unprofitable lines have been shut down.
The ferry service has been replaced by the Seikan Tunnel.
Hokkaido Railway's headquarter is located in Sapporo.

The Seikan Tunnel is a 53.85 km railway tunnel, with a 23.3 km long portion under the seabed.
Track level is about 140 meters below the seabed and 240 meters below sea level. It is the longest
undersea tunnel in the world. However, the Channel Tunnel, which connects the land of United Kingdom
and France, has a longer under-sea portion. The train of Kaikyo Line travels beneath the Tsugaru Syrait,
which lays between the Aomori Prefectute of Honshu island and the island of Hokkaido.

Smoking Ban in JR Hokkaido Trains

A smoke-free railway that runs a beautiful Hokkaido

Three major Japanese railway companies think that the smoking car and/or smoking booth
in a train are the superb service to train passengers.

JR-East Railway
An anti-smoking measurer of the JR-Tokai and JR-West is really putting the clock back!
The Japanese Government does not prohibit smoking in a train vehicle.

The smoking room in the train infringes the health of the passengers.

Kinki-Nippon Railway company still operates smoking vehicles.
