MARS (マルス, Marusu), which stands for Multi Access (originally Magnetic-electronic Automatic) seat Reservation System, is a train ticket reservation system used by the railway companies of former Japanese National Railways, currently Japan Railways Group (JR Group) and travel agencies in Japan, developed jointly by Hitachi and the Railway Information Systems Co., Ltd (JR Systems), a JR Group company jointly owned by the seven members of the group.[ vague ]

Outline

The host of the system is located in Kokubunji, Tokyo, and managed by JR Systems.

Ticket offices at JR stations equipped with MARS terminals are called as Midori no Madoguchi (みどりの窓口, literally "green window"), selling tickets of all JR Group trains and partly highway buses and route buses and ferries. It is possible for passengers to reserve tickets of buses and trains from one month prior to ride on.

Now, the Midori no Madoguchi is named by JR Group excluding JR Tokai. [1] [2]

History

The MARS-1 system was created by Mamoru Hosaka, Yutaka Ohno, and others at the Japanese National Railways' R&D Institute (now the Railway Technical Research Institute), and was built in 1958. [3] It was the world's first seat reservation system for trains. [4] The MARS-1 was capable of reserving seat positions, and was controlled by a transistor computer with a central processing unit consisting of a thousand transistors. [3]

The latest version of MARS uses the MARS 501 system which was introduced in 2002.

Computer reservation systems, or central reservation systems (CRS), are computerized systems used to store and retrieve information and conduct transactions related to air travel, hotels, car rental, or other activities. Originally designed and operated by airlines, CRSs were later extended for use by travel agencies, and global distribution systems (GDSs) to book and sell tickets for multiple airlines. Most airlines have outsourced their CRSs to GDS companies, which also enable consumer access through Internet gateways. Modern GDSs typically also allow users to book hotel rooms, rental cars, airline tickets as well as other activities and tours. They also provide access to railway reservations and bus reservations in some markets, although these are not always integrated with the main system. These are also used to relay computerized information for users in the hotel industry, making reservation and ensuring that the hotel is not overbooked.

Japan Rail Pass Rail pass for overseas visitors sold by the Japan Railways Group

The Japan Rail Pass, also called the JR Pass, is a rail pass for overseas visitors sold by the Japan Railways Group, and is valid for travel on all major forms of transportation provided by the JR Group in Japan, with a few exceptions. The Rail Pass is designed to stimulate travel and tourism throughout the country. It is only cost effective for long-distance travel, particularly by bullet train. While the savings from extensive travel can be considerable, those who travel too little may in fact lose money on a rail pass. The Japan Rail Pass is of limited use within larger cities. In Tokyo, for instance, it does cover the Yamanote Line which goes to several popular tourist areas as well as in Osaka on the Osaka Loop Line, plus in Kyoto on the Nara Line and Sagano Line.
