Yomiuri includes this ominous description of the incident:

An explosion was heard from the No. 1 plant at about 3:36 p.m. [10:36 p.m. Friday night PST] and white smoke was witnessed about 10 minutes later, Tokyo Electric Power Co officials said, adding that four workers were injured. However, the cause of the blast remained unknown.
