The Shinkansen is a network of high-speed railway lines in Japan. Have a network of high speed train lines that connect Tokyo with most of the country's major cities among which the Tokaido Shinkansen (Tokyo - Nagoya - Kyoto - Osaka) is the oldest and most popular. All shinkansen lines (except the Akita and Yamagata Shinkansen) run on tracks that are exclusively built for and used by shinkansen trains. Most lines are served by multiple train categories, ranging from the fastest category that stops only at major stations to the slowest category that stops at every station along the way.The Shinkansen running at speeds of up to 320 km/h, the shinkansen is known for punctuality (most trains depart on time to the second), comfort (relatively silent cars with spacious, always forward facing seats), safety (no fatal accidents in its history) and efficiency. Thanks to the Japan Rail Pass, the shinkansen can also be a very cost effective means of travel.
