Kakuei Tanaka
The JRCC was established in 1964 as the successor to JNR's railway line construction division. Kakuei Tanaka, then an influential member of the House of Representatives, was said to have been involved in its creation. Since by 1964 the existing railway network had been largely completed, the JRCC's primary responsibility was the planning and construction of the new Shinkansen lines, urban railway lines, and third-sector lines.
