Eleven people have died from complications related to physical and mental hardships stemming from the Kyushu earthquakes, Kumamoto Prefecture revealed on April 20.
The deaths bring total quake-related fatalities since the first major temblor struck on April 14 to 58.
The prefecture has categorized earthquake-associated deaths as those caused by illness from the physical and mental stress resulting from sleeping in cars or living in evacuation centers. Such conditions include so-called economy class syndrome -- the formation of blood clots due to prolonged periods of physical inactivity.
A 51-year-old woman from the city of Kumamoto's Nishi Ward, who had been sleeping in a car parked by her home, died from the condition on April 18. In another case, a 77-year-old woman was found dead inside the bathroom of an emergency shelter on April 17 in the city of Aso.
Two individuals from the town of Mashiki who had been taken to the hospital following the earthquake on April 16 were later also confirmed dead.
Meanwhile, a woman who was found deceased on April 19 at the site of a landslide that hit the Log Sanso Hinotori cottages in the Nagano district of Minamiaso, Kumamoto Prefecture, was identified as Yoko Torii, 37, of Higashikagawa, Kagawa Prefecture, Kumamoto Prefectural Police announced on April 20. She was the wife of Takanori Torii, 42, whose body was found nearby on April 18.
With the discovery of Yoko Torii's body, there are now three people listed as missing in the quake disaster.
