General Project Plan of Japan Natural Gas Pipeline
The consumer price of natural gas in Japan is more than double, comparing with international price levels, because Japan has long term LNG purchase contracts as "Take or Pay" bases. And its country is far isolated from the continents and it was considered to be difficult to establish piepeline networks offering reasonable price gas sypply.
This project is able to break such current stagnated business structures, and it might be trigger to stimulate deregulations of the energy supply business.
This project is in a strong position to proceed, comparing to other plans, as this can be started by the agreements between Japan, Russia and major oil companies, being free from tough multi-country negotiations. The most advantageous merit are to treat abundant russian gas reserves for 100 years, initially from Sakhalin Island and later from East Siberian regions, by the pipeline systems. This realization results in offering stable & cheap price gas like coals and oils in entire Japanese territory.
Natural gas supplying routes to specifiec regions are:
- Metropolitan Area Pacific Route
- Center & West Industrial Areas Japan Sea Route
- Tokai Area Pacific Route
- Sikoku, Kyushu Areas Japan Sea Route
Different from batch systems with LNG carriers, this completion can bring about the establishing the commodity gas market in Japanese economy systems, expanding LNG storage capacities.
