Extension of Shin Tokyo Line (Natural Gas Pipeline), Japan


INPEX CORPORATION announced today that it has decided to extend another 19km of
the existing Shin Tokyo Line (Natural Gas Pipeline). Upon completion of the extension,
Shin Tokyo Line will be 213km long and will carry natural gas from Joetsu City, Niigata
Prefecture to Fujioka City, Gunma Prefecture. It will be connected at Fujioka City to the
existing Tokyo Line (Natural Gas Pipeline), which runs parallel with Shin Tokyo Line.

Extension of Shin Tokyo Line will enhance INPEX’s supply capability of natural gas for its
customers in the medium to long term. As in the past, we continue to make efforts to
supply environmentally friendly natural gas through our wide-spanning pipeline network in
the Tokyo metropolitan area and seven other prefectures spreading peripherally in the
center of Honshu Island, Japan.
