A 7.1-magnitude earthquake struck southern Japan, triggering a devastating partial collapse at the Æon Mall in Kashima, Kumamoto Prefecture, following a suspected gas explosion. Emergency teams rescued four injured individuals while 10 others remained unaccounted for, amidst widespread power outages affecting tens of thousands of households across the region.
What began as a severe seismic event quickly escalated into a complex rescue operation as structural damage and suspected utility failures compounded the crisis. The tremor struck at approximately 4:27 p.m. local time, registering at the maximum Level 7 on Japan’s seismic intensity scale, according to official reports detailed by state broadcaster NHK and local authorities.
The Mall Collapse and Rescue Operations in Kashima
The most severe structural disaster unfolded at the Æon Mall in Kashima, where the second floor of the commercial building collapsed. Kumamoto Prefecture’s emergency response team confirmed that four injured victims had been successfully pulled from the rubble and transported to local hospitals, in a rescue effort where the fate of 10 others remains unknown, and the volume of damage is still under investigation while search and rescue operations continue. However, rescue crews faced dangerous conditions as they searched for roughly 10 people whose whereabouts remained unknown.
Witness accounts from the scene paint a chaotic picture of the moments following the initial shock. One shop owner described evacuating after the earthquake alarm sounded, only to hear a massive detonation roughly an hour later in an account reported by Asahi.

Staff members working inside the complex also reported smelling gas after returning from helping customers evacuate, immediately prior to the blast according to TBS coverage. A female employee at the shopping center told the Japanese TV station TBS that she and her colleagues sensed the smell of gas when they returned to their stores after helping shoppers evacuate the building, before hearing the sound of the explosion. While national broadcaster NHK and local fire officials pointed to a suspected gas leak as the catalyst for the secondary collapse, official investigations into the exact structural failures are ongoing.
Widespread Infrastructure Disruptions Across Kumamoto
The 7.1-magnitude tremor and its aftermath severely strained regional infrastructure across southern Japan. Kyushu Electric Power Company reported that approximately 48,000 households lost electrical power in Kumamoto Prefecture alone.
In a press briefing following the disaster, Prime Minister Sanae Takaichi announced that the national government had already received verified reports of physical damage to local bridges and roadways, alongside the widespread power failures. A specialized government evaluation team was immediately deployed to the worst-hit areas to assess the damage on the ground as outlined in government briefings. Fire officials in Kumamoto Prefecture in southern Japan reported an explosion at a shopping center in Kashima town within the prefecture, with officials explaining via Japan’s national broadcaster NHK that part of the second floor of the mall building collapsed following the explosion.
Evacuation Orders and Aftershocks
The Fire and Disaster Management Agency issued urgent evacuation directions affecting more than 260,000 residents, with the majority located in Kumamoto and neighboring Nagasaki prefectures pursuant to agency statistics.
The initial major tremor was followed by a series of significant aftershocks. Seismologists recorded subsequent seismic activity reaching up to Level 5 on the Japanese intensity scale, compounding the danger for emergency personnel attempting to secure damaged buildings.
