AEON Mall Kumamoto Explosion Leaves Three Dead After Magnitude 7 Earthquake

A massive earthquake registering a maximum seismic intensity of 7 struck Kumamoto Prefecture on July 28, 2026, at approximately 4:27 p.m., centered in Uki City and Hikawa Town. The disaster triggered severe structural damage, including a deadly explosion at a major shopping center, collapsing industrial infrastructure, and widespread disruptions to transportation networks across Kyushu.

AEON Mall Kumamoto Explosion and Casualties

At the AEON Mall Kumamoto located in Kashima Town—where the earthquake intensity was estimated at upper 6—an explosion occurred at approximately 5:50 p.m. on July 28, roughly one hour and twenty minutes after the initial tremor, according to explanations provided by AEON President Akio Yoshida during a press conference in Kumamoto City. Yoshida stated that more than 4,000 visitors and employees were inside the facility when the earthquake struck, noting that management had issued evacuation instructions before the blast ripped through the second-floor area.

According to reports from Kumamoto Prefecture and government officials, three tenant employees died in the building collapse at the shopping center, while another person was left in a heart-lung arrest state. Fire and police search teams reported detecting a gas smell inside the damaged structure during rescue operations. Yoshida noted that the commercial facility had used LP (liquefied petroleum) gas since opening in 2005 without any prior trouble reported regarding gas leaks, while authorities continue investigating the exact cause of the explosion.

Industrial Infrastructure Damage at Nippon Paper Yatsushiro Plant

In Yatsushiro City, where an intensity of upper 6 was recorded, the Nippon Paper Yatsushiro plant suffered catastrophic damage when a factory chimney collapsed. Municipal reports confirmed that 11 people were trapped inside the facility’s buildings. Rescue teams successfully pulled seven individuals from the wreckage, but five of those victims ultimately died, and search operations continued for four others whose whereabouts remained unknown.

Prefecture-Wide Casualties and Lifeline Disruptions

Chief Cabinet Secretary Minoru Kihara stated in a press briefing that the prefectural toll reached 13 deaths and five heart-lung arrest cases by the following day, alongside approximately 36 injured residents across the disaster zone. The Cabinet, led by Prime Minister Sanae Takaichi, convened an emergency disaster response headquarters meeting—the first such mobilization since the January 2024 Noto Peninsula earthquake—to coordinate rescue efforts and secure refuge environments amid intense summer heat.

Transportation infrastructure sustained heavy blows. The Ministry of Land, Infrastructure, Transport and Tourism reported that the Kyushu Shinkansen bullet train system halted operations entirely after rail buckling occurred at facilities including the Kumamoto General Shinkansen Depot in Minami Ward. JR九州 announced plans to partially resume services between Hakata and Chikugo-Funagoya on the afternoon of July 29 with reduced frequencies. Meanwhile, historic landmarks suffered severe impacts, with the Kumamoto Castle complex sustaining 28 stone-wall collapses and four structural cracks in its keep’s earthen walls.

Emergency Response and Extreme Weather Challenges

Prime Minister Takaichi instructed disaster ministers to execute life-saving and rescue operations overnight and directed officials to supply gasoline to accommodate victims sheltering in vehicles. Evacuees also faced punishing weather conditions as Kumamoto City recorded a high temperature of 35.1°C on July 29, compounding hardships for residents dealing with suspended water, electricity, and underground utility services.

I would like to express my deepest condolences to those who lost their lives and extend my deepest apologies to the bereaved families. Our company will respond with sincerity. Akio Yoshida, President of AEON
