Teikoku Oil Co., Ltd. (TOC) completed Shizuoka-line (Koufu to Gotenba-City, 81km) at the end of 2006. Also, Shizuoka Gas Co., Ltd. (SZG), Tokyo Gas Co., Ltd. and TOC completed the Minamifuji-pipeline (Gotenba to Fuji-City, 31km) at that time. Those pipelines are in series and, with those completion, natural gas pipeline system between the Japan Sea and the Pacific Ocean was realized connecting with the Minami-nagaoka natural gas field (also with the Sekihara underground gas storage) in Niigata prefecture and the Sodeshi LNG receiving terminal of SZG in Shizuoka prefecture. Since domestic gas and imported gas (LNG) can be fed into the pipeline system, it is strongly expected that gas supply in the eastern area of Honshu Island becomes more flexible and reliable.
