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%.

Japan has the world's longest life expectancy, and is known for often being home to the world's oldest living person - though some studies contest the actual number of centenarians worldwide.

It is also one of the fastest ageing societies, with residents often having a healthier diet but a low birth rate.

The oldest person in Japan is 114-year-old Shigeko Kagawa, a woman from Yamatokoriyama, a suburb of the city Nara. Meanwhile, the oldest man is Kiyotaka Mizuno, 111, from the coastal city of Iwata.
