NRA said pumps went offline for spent pools at reactor number one and three. Pumps for reactor number three were restarted at 12:22 am local time. The regulator said there's "enough time" to restart pumps at reactor number one. It also said fire alarms were triggered at the plant's number five turbine though details are scant. 

Kyodo News reports radiation levels at the plant are normal. This is the same nuclear power plant that went into a meltdown eleven years ago after a powerful earthquake. The plant has since been halted.

Update (1219ET): A Tohoku Shinkansen bullet train has "derailed," according to Bloomberg's Gearoid Reidy.
