The oldest person living in Japan is 114 years old, reports the BBC. But "The number of people in Japan aged 100 or older has risen to a record high of nearly 100,000, its government has announced." Setting a new record for the 55th year in a row, the number of centenarians in Japan was 99,763 as of September, the health ministry said on Friday. Of that total, women accounted for an overwhelming 88%... Health minister Takamaro Fukoka congratulated the 87,784 female and 11,979 male centenarians on their longevity and expressed his "gratitude for their many years of contributions to the development of society".... The higher life expectancy is mainly attributed to fewer deaths from heart disease and common forms of cancer, in particular breast and prostate cancer. Japan has low rates of obesity, a major contributing factor to both diseases, thanks to diets low in red meat and high in fish and vegetables. The obesity rate is particularly low for women, which could go some way to explaining why Japanese women have a much higher life expectancy than their male counterparts... But it's not just diet. Japanese people tend to stay active into later life, walking and using public transport more than elderly people in the US and Europe... However, several studies have cast doubt on the validity of global centenarian numbers, suggesting data errors, unreliable public records and missing birth certificates may account for elevated figures. A government audit of family registries in Japan in 2010 uncovered more than 230,000 people listed as being aged 100 or older who were unaccounted for, some having in fact died decades previously. The miscounting was attributed to patchy record-keeping and suspicions that some families may have tried to hide the deaths of elderly relatives in order to claim their pensions.Read more of this story at Slashdot.
