A massive earthquake with a magnitude of 5.9, shook Tokyo and surrounding areas overnight on Thursday.
The quake started at around 10:40 pm local time in the Chiba prefecture, east of the capital, registering an intensity of "five-plus" on Japan's seismic scale of zero to seven in areas like Tokyo and Saitama.
The tremors were strong enough to stop trains, burst water pipes and cause power cuts across the cities.
Newly elected Prime Minister Fumio Kishida immediately set up an emergency response task force to provide everyone with the latest information.
The quake occurred just three days after the new prime minister took office.
As of now, authorities have reported 17 injuries, but no deaths or major structural damage.
Japan Meteorological Agency added that the country is not at risk of a tsunami.
However they urged people in the greater Tokyo area to stay alert for the next seven days in case more earthquakes come their way.
They also described Thursday's quake as the strongest to hit the capital region since 2011.
In March of 2011, a 9.0 magnitude quake shook the country's northeastand damaged the Fukushima Daiichi nuclear power plant…which still remains as the world's worst nuclear crisis after Chernobyl.
Japan accounts for around 20 percent of the world's mega earthquakes with a magnitude 6 or greater.
