Several people are trapped inside a shopping centre after a strong earthquake hit south-west Japan, the local fire service says.
There were reports of an explosion at the Aeon Mall in Kumamoto, following the magnitude 7.1 earthquake.
The quake hit inland on Kyushu island at 16:27 local time (07:27 GMT), with more than 150,000 people being told to move to evacuation shelters. There was a brief tsunami warning that was lifted within the hour.
The quake with a magnitude of 7.1 struck south-west Japan on Tuesday afternoon local time.
Thousands of homes lost power and there was damage to roads.
Japan is one of the world's most earthquake-prone countries, experiencing around 1,500 earthquakes a year.
The meteorological agency has warned of strong aftershocks given the shallow epicentre - 10km (six miles).
Japanese news agency NHK reports a witness seeing an explosion and smoke at the shopping mall.
The witness saw the second floor of the building collapse, with some shoppers taken to hospital.
Japan’s fire and disaster management agency later confirmed that the second floor of a "commercial facility" collapsed, with many people trapped inside.
Speaking earlier - before the confirmation of trapped shoppers - Japanese Prime Minister Sanae Takaichi said her teams had "been informed that there are already some injured people".
She also said there had been reports of damage to roads and infrastructure, "as well as collapsed buildings".
She urged residents to evacuate to a safe location, and said injuries and the extent of the damage were being assessed.
Tuesday's earthquake caused "no damage or safety issues" at the Sendai nuclear power plant, around 100km from the epicentre of the quake, says the international atomic watchdog.
In a post on X, the International Atomic Energy Agency says that the plant "remains in operation" and the group will "continue to monitor the situation".
