The epicentre of quake, the biggest of several sizable aftershocks on Monday, was 56 miles east of the Fukushima Daiichi nuclear complex at the centre of the crisis.
The biggest tremor forced engineers to postpone plans to remove highly contaminated water from one reactor, but nuclear safety officials said work had resumed by nightfall.
The government announced earlier that because of accumulated radiation contamination, it would encourage people to leave certain areas beyond its 12-mile exclusion zone around the plant.
Children, pregnant women, and hospitalised patients should stay out of some areas 12-19 miles from the nuclear complex, Chief Cabinet Secretary Yukio Edano told reporters.
