A strong earthquake of 6.0-magnitude hit outskirts of Tokyo in Japan on Saturday, according to a meteorological agency in Japan.
The quake hit at 8:23 pm (1123 GMT), at a depth of 39 km, off the east coast of Honshu, Japan, the US Geological Survey said.
Buildings in the capital were seen swaying, say residents.
However, no tsunami warning was issued, the country's meteorological agency said, adding there were no immediate reports of damage after the quake.
The quake comes several weeks after a deadly tremor rocked the Osaka region, killing five people and injuring over 350.
Japan sits on the Pacific "Ring of Fire" where many of the world's earthquakes and volcanic eruptions are recorded.
On March 11, 2011, a devastating 9.0-magnitude quake struck under the Pacific Ocean, and the resulting tsunami caused widespread damage and claimed thousands of lives.
It also sent three reactors into meltdown at the Fukushima nuclear plant, causing Japan's worst post-war disaster and the most serious nuclear accident since Chernobyl in 1986.
