Japan Railway Construction, Transport and Technology Agency

The Japan Railway Construction, Transport and Technology Agency was established on 1 October 2003 by an act of the National Diet through the merger of two public corporations: the Japan Railway Construction Public Corporation (JRCC) and the Corporation for Advanced Transport and Technology (CATT). The JRCC had been established in March 1964 to oversee the construction of Shinkansen and other railway lines. In October 1998, the Japanese National Railway Settlement Corporation was merged into JRCC, following the completion of its role in liquidating the remaining assets of Japanese National Railways (JNR) after its division and privatization in April 1987. CATT was formed in October 1997 through the merger of the Maritime Credit Corporation, which managed joint-ownership shipbuilding projects, and the Railway Development Fund, which provided subsidies for railway construction. The Railway Development Fund itself had been established in October 1991 from the remnants of the Shinkansen Holding Corporation, which had been responsible for holding the ownership of Shinkansen lines still under construction at the time of JNR’s privatization. In March 2001, the Association for Structural Improvement of the Shipbuilding Industry was merged into CATT. ==Lines of business==
