Since 1984, JAPEX has been using tank trucks to supply imported LNG to LDCs in Tohoku, Hokuriku and other regions of northern Honshu from an LNG receiving terminal in the port of Niigata. JAPEX further improved this system by introducing rail transportation using LNG tank containers for the first time in Japan in 2000. This system allows JAPEX to supply LNG to customers in distant areas for whom using tank trucks would be costly. Using this method, JAPEX has been supplying LNG to LDCs in Ishikawa and Toyama Prefecture. Rail transport using LNG tank containers is an environmentally friendly mode of transportation with lower CO₂ emissions than tank trucks.

JAPEX has constructed a natural gas liquefaction plant at the Yufutsu oil and gas field to supply natural gas to customers in Hokkaido in geographic areas outside the reach of its pipeline network. Shipments of LNG by road and rail to LDCs in Hokkaido began in October 2003 using a container system we call the LNG Satellite System. The Yufutsu LNG Plant is a groundbreaking project that has paved the way for the supply of LNG in Hokkaido. In addition, we completed the second train at the Yufutsu LNG plant in November 2007. Looking ahead, plans call for promoting the introduction of natural gas and expanding supply volumes with an emphasis on LDCs far from the Yufutsu oil and gas field.

Construction of the Yufutsu LNG receiving terminal commenced in June 2010. From autumn 2011, externally procured LNG will be transported by coastal vessel and optimally mixed with natural gas produced by the Yufutsu oil and gas field. This will allow JAPEX to bolster its natural gas supply structure within the Hokkaido area.
