The incident began with a magnitude‑7.1 earthquake striking Kumamoto Prefecture on 28 July 2026, followed by a secondary gas explosion at Aeon Mall Kumamoto in Kashima about an hour later. The explosion resulted in seven deaths.

Investigations by police, fire services, and the Ministry of Economy, Trade and Industry (METI) identified a leak of liquefied petroleum (LP) gas, likely caused by damage to distribution piping during the quake, as the cause. In response, Aeon established an accident investigation committee comprising legal and technical experts to identify causes and develop prevention measures. The company is also investigating reports of individuals re-entering the facility before safety confirmations were completed.

One tenant company, Habita Inc., admitted that management instructed employees to re-enter the damaged store to deposit the day's cash takings after they had already evacuated. This decision has drawn significant criticism regarding crisis management and the failure to prioritize safety over business operations. METI has announced a nationwide review of LP-gas safety standards for large facilities, such as shopping malls and schools, to prevent similar tragedies.
