Discovered in 1979 and in production since 1984, the Minami-Nagaoka Gas Field is one of the largest in Japan. After processing, the natural gas is transported through an about 1,400-km trunk pipeline network stretching across the Kanto and Koshinetsu regions that surround the greater Tokyo metropolitan area and delivered to city gas companies and industrial customers along this network. Most users of the natural gas are in Niigata Prefecture, due to its proximity to the Minami-Nagaoka Gas Field, followed by customers in Gunma, Saitama and Nagano prefectures.
INPEX has experienced steady growth in sales of natural gas volume due to sharp rises in the prices of competing fuels, as well as the highly environmentally friendly attributes of natural gas. In addition to its role as a fuel for thermal energy, natural gas is expected to be used for a wide variety of applications, such as a fuel for onsite power generation and co-generation, as well as a raw material for chemical products. INPEX targets annual sales of 2.5 billion m³ by the early 2020s and as much as 3.0 billion m³ over the long term, reflecting further capacity increases for our Shin Tokyo Line and development of the Toyama Line (extending from Itoigawa City, Niigata Prefecture, to Toyama City, Toyama Prefecture), construction of which began in April 2012.
At the Naruto Gas Field in Chiba Prefecture, natural gas is being produced from water-soluble gas fields. After extracting natural gas from underground water (brine water), the brine water is used to produce iodine, which is exported to Europe, the United States and elsewhere.
