Two women who died in an explosion at an Aeon shopping centre following a powerful earthquake in Japan’s Kumamoto prefecture last week were instructed by their employer to return inside to put sales proceeds in a safe, according to the company.Two executives of Habita, which operates the variety store where the women died, said on Sunday they apologised to the family of one of the victims, 22-year-old Kurumi Otake, at her wake and handed over a written account of events.Otake evacuated from the Aeon shopping centre in Kashima following the magnitude 7.1 temblor on Tuesday but was later seen re-entering the building.“[My daughter] isn’t coming back,” Otake’s mother said in tears.Heavy machinery removes debris at Aeon Mall Kumamoto on Friday.
