Japan's northeastern region braced for aftershocks Sunday following an earthquake of magnitude 7.3 overnight that injured more than 150 people, cut power and water, and disrupted bullet train services, with some residents looking weary as they tidied up the mess in their homes and shops.

No deaths were attributed to the temblor that struck at 11:07 p.m. Saturday, registering upper 6 on Japan's seismic intensity scale of 7 in parts of Fukushima and Miyagi, the prefectures devastated by a magnitude-9.0 quake and tsunami in March 2011 that left more than 15,000 people dead and triggered a nuclear crisis.

While a tsunami did not occur, Saturday's quake provided a chilling reminder of that disaster, just weeks before its 10th anniversary.
