The Japan Railway Construction, Transport and Technology Agency (鉄道建設・運輸施設整備支援機構, Tetsudō Kensetsu Un'yu Shisetsu Seibi Shien Kikō), or JRTT, is an Independent Administrative Institution (独立行政法人, Dokuritsu gyōsei hōjin) created by an Act of the National Diet, effective 1 October 2003. JRTT was founded by integrating the Japan Railway Construction Public Corporation (JRCC) and the Corporation for Advanced Transport and Technology (CATT).

As its name implies, JRTT is involved in construction and technical support for railway and other transportation projects throughout Japan. JRTT has undertaken numerous railway construction projects during its existence, including:

• Nagoya Subway Meijo Line (2004)
• Kyushu Shinkansen (2004)
• Meitetsu Airport Line (2005)
• Tsukuba Express (2005)
• Osaka Higashi Line (2008)
• Tokyo Metro Fukutoshin Line (2009)
• Narita Sky Access Line (2010)
• Eastern Kanagawa Rail Link (2023), becoming the Sōtetsu–JR Link Line, and Sōtetsu–Tōkyū Link Line (consisting of the Sōtetsu Shin-yokohama Line, and the Tōkyū Shin-yokohama Line).^[1]

JRTT is currently working on construction of the Hokuriku Shinkansen and Hokkaido Shinkansen high-speed rail projects.

In addition to its railway construction projects, JRTT has also sponsored maritime research, including the latest ship used as the JR Miyajima Ferry.

JRTT also performs administrative functions related to the liquidation of the Japanese National Railways, such as management of JNR employee pensions.

JRTT is currently the parent entity of the following JR Group companies:

• Hokkaido Railway Company
• Shikoku Railway Company
• Japan Freight Railway Company

In 2011, the National Diet passed legislation requiring JRTT to use its retained earnings from other businesses for the purpose of Shinkansen construction and capital expenditures at its subsidiary railway companies.

JRTT was also a shareholder of the West Japan Railway Company, the Central Japan Railway Company and the Kyushu Railway Company before offering those shares to the public. (The East Japan Railway Company was privatized shortly before JRTT was founded.)
