Southern Japan was hit by a magnitude 7.0 earthquake early Saturday morning, just one day after a quake killed nine people in the region.
The quake's epicentre was near Kyushu island, 1 kilometre south-west of the city of Kumamoto and 12 kilometres north-east of Uto, according to the US Geological Survey.
Japan had issued a tsunami advisory for the nearby coast but the country's meteorological agency later reported that all warnings had been lifted.
The region was rocked by Japan's strongest earthquake in five years on Friday, in which at least nine people died and over 1,100 were injured, according to figures from the emergency services.
Several aftershocks were recorded following Friday's and Saturday's quakes.
Japan is one of the most earthquake-prone countries in the world. Strict building regulations mean that damage to infrastructure is often minimal even after strong earthquakes.
