Japan's earthquake death toll rises as rescuers race through debris and aftershocks

The phones in Kumamoto lit up again Wednesday night with the familiar pulse of earthquake warnings. Another tremor—this one measuring 5.8 on the magnitude scale—rippled through the region, adding to the cascade of aftershocks that had already shaken the southern Japanese island of Kyushu more than 100 times since Tuesday's devastating 7.1-magnitude quake. For residents and rescue workers alike, each new alert meant bracing for impact, knowing that the ground beneath them remained unstable and dangerous.

By Wednesday, at least 23 people had been confirmed dead, with the toll still climbing as emergency crews and military personnel picked through collapsed structures across the region. The worst damage centered on the Aeon Mall in Kashima, where an explosion had torn through the shopping complex shortly after the initial earthquake struck Tuesday evening. The blast had collapsed an entire floor, trapping people in the rubble and killing at least three. A fourth person had gone into cardiac arrest, and three others remained unaccounted for. The mall's management reported that roughly 3,000 customers had been evacuated to a parking lot immediately after the quake, but some had apparently returned inside before the explosion ripped through the building, sending debris flying into the lot where people had gathered. One woman, Katsura Kaori, whose family members were inside when the quake hit, described how staff had guided people out efficiently—but also how chunks of explosive debris had rained down on those waiting outside. She spoke of a young man in her neighborhood who had not been able to reach his mother, who worked at the centre.

The cause of the explosion remained under investigation, though authorities suspected a gas leak. The mall's president, Yoshida Akio, declined to make definitive statements during a press conference, but regional officials had already begun urging residents to check their own gas lines. A truck passing nearby had been struck by flying debris and severely damaged; the driver had been injured, though a nearby resident had helped get him to a hospital. The weight of this disaster was compounded by memory. The Aeon Mall had only recently reopened after being heavily damaged in a 2016 earthquake that had killed more than 270 people and injured nearly 3,000. For people in the region, the trauma of that event—a decade old but still vivid—made the current crisis feel like a return of something they had not fully escaped.

Damage extended far beyond the shopping centre. A smokestack at a paper mill had collapsed, killing at least two people. Across the region, homes, roads, and shrines lay in ruins. In the Nuyamazu district, a pair of temple gates at a 16th-century Buddhist temple had toppled—gates that had been repaired just five years earlier. More than 9,000 people had sought shelter at evacuation centres, their homes either destroyed or deemed unsafe to occupy.

Rescue operations faced a compounding crisis: heat. The region was in the grip of a heatwave, with temperatures expected to reach 40 degrees Celsius in the coming days. For people trapped in rubble, for those crowded into evacuation centres, and for the rescue workers themselves, the combination of structural danger and extreme heat posed a severe threat. Japan's meteorological agency issued a stark warning, urging everyone in affected areas to be vigilant against heat stroke and related illnesses. In response, five naval vessels had been dispatched with relief supplies, and 300 air conditioners had been flown in for the evacuation centres. Bullet train services remained suspended across the region. Aso Kumamoto Airport had resumed operations on Wednesday, though some airlines had cancelled flights as a precaution.

With aftershocks continuing to rattle the ground and rescue workers racing against both time and the elements, the full scope of the disaster was still unfolding. The region remained on edge, each tremor a reminder that the earth had not finished moving.
