I wonder how much the life expectancy of the Japanese has been over estimated. In the article below the government claims not by much as they don't count folks over age 98, but if 230,000 folks over a 100 cannot be located because their families have been claiming benefits decades after they died, one wonders how many of the 80 and 90 year olds claiming benefits are also dead.

The nationwide survey was launched in August after police discovered the mummified corpse of Sogen Kato, who at 111 was listed as Tokyo's oldest man, in his family home 32 years after his death.
Kato's granddaughter has been arrested on suspicion of abandoning his body and receiving millions of yen in pension payments after his unreported death.
Soon after came the discovery that a 113-year-old woman listed as Tokyo's oldest resident had not been seen by her family for more than 20 years. Welfare officials have yet to locate Fusa Furuya, who was last seen in about 1986.
