MARS (ticket reservation system)
 | This article needs additional citations for verification. (April 2019) |
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 computer of the system was previously located in Kokubunji, Tokyo until 2013, when it was moved to an undisclosed location in the northern part of the Kantō region.[1] The system is managed by JR Railway Information Systems since 1 April 1987.
Ticket offices at JR stations equipped with MARS terminals are called 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 the given trip.
Currently the Midori no Madoguchi is named by JR Group.[2][3]
History
MARS-1

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.[4] It was the world's first seat reservation system for trains, and entered service in February 1960, initially only providing bookings for the Kodama and Tsubame limited express services.[5] The MARS-1 was capable of reserving seat positions, and was controlled by a Hitachi mainframe transistor computer with a central processing unit consisting of a thousand transistors and a magnetic drum memory unit for data storage, which was where the MARS acronym originated from.[4]
In 2008, the MARS-1 system received a "One Step on Electro Technology -Look Back to the Future-" commemorative plaque from the Institute of Electrical Engineers of Japan.[6]

MARS 500
MARS 501
Introduced in stages between 2002 and 2004, the MARS 501 introduced the concept of an Ethernet-based client–server model. Also, the ticket paper type was changed to thermal paper.
MARS 505
The latest version of MARS uses the MARS 505 system which was introduced in April 2020, which expanded on contactless and ticketless boarding and booking capabilities brought along by the rise of mobile apps on smartphones and tablets.[7]
