Japanese Shinkansen

The Shinkansen (新幹線) is the fastest train in Japan, which was started to operate by four Japan Railways Group companies in 1964, in time for the first Tokyo Olympics. This revolution has significantly impacted on Japanese society, economy, environment and culture.
The Shinkansen connect most major cities on the island of Honshu and Kyushu, with construction of a link to the northern island of Hokkaido underway.

This has made a long distance trip much easier and more comfortable.
On the Shinkansen, attendants keep selling various types of bento (lunch box), soft drinks, alcohol and snacks.
The Shinkansen currently travels at speeds between 200-300 km/h and the speeds are expected to increase to the maximum of 360 km/h by 2020.
