 Next up, Tokyo. In 2010, when officials in Tokyo went to congratulate 111-year-old Sojin Kato on being the city's oldest man alive, they were turned away by his 81-year-old daughter. After welfare officials were denied a visit several times, they became suspicious and asked the police to investigate. They soon discovered Kato's mummified body wearing underwear and pajamas lying in bed covered with a blanket.
