It is widely known that the number of centenarians (people over 100 years old) in Japan is much higher than the rest of the world. This long life expectancy is often attributed to the lifestyle and diet of the culture.

In 2010, a 111 year old was listed as the oldest living male in Tokyo, but he was discovered in his bed mummified having died 30 years earlier. This launched a police investigation into people over the age of 105. It was discovered that 234,354 Japanese centenarians were “missing”.
