A strong earthquake with a preliminary magnitude of 6.9 hit southwestern Japan on Monday.
Japan’s Meteorological Agency says the quake, centred at a depth of 30 kilometers, shook a wide area in Kyushu, the southwestern main island.
There were no immediate reports of damage or casualties.
The quake triggered a tsunami advisory and residents in some coastal areas were told to evacuate as a precautionary measure.
State television reported that waves estimated to be as high as one metre reached land within 30 minutes of the quake.
It said the waters detected at Miyazaki Port measured 20 centimeters.
The meteorological agency says aftershocks can strike over the next week, especially in the next two or three days.
It warns people to watch out for landslides as well as falling objects in homes.
