Railway Information Systems Co., Ltd. (Japanese: 鉄道情報システム株式会社, Hepburn: Tetsudō Jōhō Shisutemu Kabushiki Gaisha) is a Japanese information and communications technology company. It is commonly known as JR Systems (JRシステム, Jei-Āru Shisutemu), and its corporate color is maroon.
On 1 April 1987, the company succeeded to the operation and management of computer systems—including the MARS ticket reservation system—from the Japanese National Railways (JNR), and became part of the Japan Railways Group (JR Group). Its head office is located in Shibuya, Tokyo, inside the JR East headquarters building.
The company's core business is the development, operation, and management of information systems for the JR Group companies, including the MARS system used at Midori no Madoguchi (ticket offices) and ticket vending machines. The company is a joint venture owned by the six passenger rail companies of the JR Group and the Japan Freight Railway Company (JR Freight).
