Japan's Meteorological Agency says the tsunami danger level in quake-hit areas remains high.　↑

The agency's chief of tsunami monitoring, Hirofumi Yokoyama, told a news conference on Friday night that tsunamis have continued to hit Pacific coastal regions at intervals of about one an hour since the quake.

He asked people in areas where tsunami warnings have been issued to exercise caution.

He said people should also remain on high alert for strong aftershocks, which could cause landslides or topple more buildings.
