Indonesian and Australian coal exporters are moving aggressively to fend off competition to meet Japan's new-found appetite for the fuel to generate electricity while the country's nuclear reactors remain offline after the Fukushima disaster. Japan's coal imports are set to hit another record over the next year as utilities led by TEPCO burn more of the cheaper fuel to cut surging energy bills that pushed the nation into a record trade deficit last year.

Members of a review mission from the International Atomic Energy Agency (IAEA) walk near the No.4 reactor building at Tokyo Electric Power Co. (TEPCO)'s tsunami-crippled Fukushima Daiichi Nuclear Power Plant in Fukushima, in this handout photograph taken by IAEA on April 17, 2013. Japan's crippled Fukushima nuclear plant halted cooling of a spent fuel pool at the site on Monday to remove two dead rats, the third time cooling equipment has gone offline in five weeks because of rodents. The IAEA said it believed Tepco could handle the job, but said the contaminated water was its "biggest challenge". Picture taken April 17, 2013. Mandatory credit.
A pair of dead rats are seen inside the box of a transformer for the cooling system of the No.2 reactor's spent fuel pool at Tokyo Electric Power Co. (TEPCO)'s tsunami-crippled Fukushima Daiichi Nuclear Power Plant in Fukushima, in this handout photograph provided by TEPCO on April 22, 2013. Tepco halted the cooling system for the spent fuel pool for inspection on Monday after it found dead rats near a transformer, it said in a statement, the third time a cooling system has been offline there in the past five weeks, underlining the challenges the utility faces in trying to shut down the facility.
