Sogen Kato

Sogen Kato was a Japanese man thought to have been Tokyo's oldest man until July 2010, when his mummified corpse was found in his bedroom. It was concluded he had likely died in November 1978, aged 79, and his family had never announced his death. Relatives had rebuffed attempts by ward officials to see Kato in preparations for Respect for the Aged Day later that year, citing many reasons from him being a "human vegetable" to becoming a Sokushinbutsu. The cause of death was not determined due to the state of Kato's body.
