(TOKYO) — A series of earthquakes rocked Japan early Saturday, waking up nervous residents near Tokyo.
The strongest quake was a magnitude 5.5 near Mt. Fuji, just hours outside the capital city.
No tsunami warning was issued, and no serious damage reported, but it rattled plenty of nerves. Tremors continue to rock Japan nearly a year after a catastrophic quake and tsunami killed thousands.
Earlier this week, researchers announced “the big one” could hit near Tokyo in the next four years.
