JRTT owns the Shinkansen lines it constructed, along with the Eastern Kanagawa Rail Link, and rents these lines to their operators.

JRTT is currently working on construction of theHokuriku Shinkansen andHokkaido Shinkansen high-speed rail projects.

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

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