The magnitude 7.1 earthquake hit Kumamoto Prefecture on Japan's southern main island of Kyushu on Tuesday. The Aeon Mall, in the town of Kashima, was one of the hardest-hit sites, after an explosion that followed the quake caused the walls and a floor to collapse.
The explosion, which the company said it believes was due to a gas leak, occurred after about 3000 shoppers had been evacuated to a parking lot following the quake, but some employees remained inside. The mall's second floor collapsed.
Rescuers extracted five people from under mall debris and retrieved the bodies of seven others over the past five days. On Saturday, officials said all the missing were accounted for and ended the operation at the mall.
The overall number of missing in the hit prefecture remains unknown, and search operations pressed on, with thousands of Self Defense troops, police, rescue workers and sniffing dogs deployed.
Prime Minister Sanae Takaichi, at a government task force meeting Saturday, urged rescue personnel not to leave anyone behind.
At another hard-hit site in Kumamoto Prefecture, a chimney collapsed at the Nippon Paper Industries factory in Yatsushiro city, trapping 11 employees. Nine have since been confirmed dead and two were rescued, officials said.
The earthquake has left 103 people injured in Kumamoto, authorities said, and two in addition to the reported deaths are being investigated to determine if they are quake-related.
The prefecture's main challenge is the lack of fresh water affecting nearly 70,000 homes, and fuel shortages as Japan suffers sweltering heat, stoking fears of heat-related illness. Japan Meteorological Agency said temperatures reached an "extreme heat" level of 36.6 C in Kumamoto city Saturday.
More than 9000 people remain at crowded shelters, such as converted community centres, school gyms and classrooms. Many others slept in cars parked at town hall parking lots and parks, or outside of their homes, for privacy.
Experts have long criticised Japan's crowded conditions at emergency shelters, arguing that a lack of sanitation and privacy creates additional stress and increases the risk of health problems for disaster-hit people.
Water, food and other necessities, including portable toilets, as well as air conditioners and partitions, were being delivered to improve conditions at the evacuation centres, Takaichi said Saturday.
"The government is determined to do everything we can," Takaichi said.
The prefecture said it has received more than 1500 reports of power loss as of Saturday, but local power company serving Kyushu said it had no immediate reports of outages.
Over 180 homes were destroyed, officials said, and nearly 3500 buildings were damaged - nearly double the number reported on Friday - with 20 of them severely affected, according to Kumamoto prefectural assessments.
