In short

The offshore event struck at 7:39 p.m. in the waters off the Kanto region, roughly 169 kilometers southeast of Asahi. Ground motion reached a 3 on the Japan Meteorological Agency's zero-to-seven scale, which is typically strong enough to rattle dishes indoors. Forecasters determined there was no tsunami threat, and local officials confirmed an absence of immediate injuries or destruction. With the nation resting atop four tectonic plates, mild tremors remain an extraordinarily common occurrence for the population.

Magnitude-6.1 quake hits off Tokyo, no tsunami alert issued

The shallow quake hit at 7.39 pm (6.39pm, Singapore time) in the sea off the coast of the country's Kanto region, the Japan Meteorological Agency (JMA) said on its website.

Its epicentre was about 169km southeast of Asahi, which is just east of the capital Tokyo, according to the United States Geological Survey.

The JMA said it recorded a "seismic intensity 3" on Japan's 0-7 scale, meaning that "almost everyone indoors feels the shaking" and "dishes on shelves may rattle".

There were no immediate reports of damage or injuries.

Japan is one of the world's most seismically active countries, sitting on top of four major tectonic plates along the western edge of the Pacific "Ring of Fire".

The archipelago, home to around 125 million people, typically experiences hundreds of jolts every year and accounts for about 18 per cent of the world's earthquakes.

The vast majority are mild,…
