The nation is probably set to receive more LNG than it needs, potentially forcing some purchasers in the world's biggest user of the fuel to resell cargoes and add to a glut.

Liquefied natural gas volumes contracted by Japanese buyers may exceed their combined demand from 2017 to 2021, according to a report compiled by the Ministry of Economy, Trade and Industry.

The report, obtained by reporters, was distributed at a closed meeting attended by officials of the government and 14 companies including Royal Dutch Shell PLC, Jera Co. and Tokyo Gas Co.
