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The ferry service has been replaced by the Seikan Tunnel.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

Three major Japanese railway companies think that the smoking car and/or
in a train are the superb service to train passengers.
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.
Kinki-Nippon Railway company still operates smoking vehicles.
