Work to cool the No. 3 reactor at the crippled Fukushima nuclear plant with water cannons began again late yesterday, Kyodo News reported.
The latest mission was scheduled to carry on into the early hours Japanese time.
So far, fire trucks from the Self-Defense Forces had sprayed more than 80 tons (72.5 tonnes) of water at No. 4 reactor yesterday, national broadcaster NHK reported.
Earlier, engineers said they had partially restored power to reactor No. 2 as they battled to bring the cooling systems back to life.
News of the resumption of work at Fukushima came as the death toll was revised upwards yet again, with the National Police Agency reporting that the number of bodies recovered so far stood at 8450, while 12,931 people were listed as missing. Agencies
