Key Takeaways
Full Summary
Sogen Kato was believed to be Tokyo's oldest man until his mummified body was discovered in 2010, having likely died in November 1978. Poor recordkeeping by officials resulted in a lack of knowledge about the status of over 234,000 centenarians in the city.
Investigative efforts included police breaking into Kato's home after his family repeatedly denied access, citing various reasons for his absence. Upon discovery, Kato's remains were found in a state suggesting he had been deceased for decades, with newspapers in the room dating back to the Shōwa period.
An autopsy could not determine the cause of death, raising concerns about the family's awareness of his condition. This case prompted officials to reassess their recordkeeping practices and the potential for similar situations in the future, emphasizing the need for better tracking of elderly individuals.
