More than 100,000 people in Japan are now aged 100 or older

The number of people aged 100 or more in Japan has exceeded 100,000 for the first time, according to the health ministry.

Figures show Japan is now home to 107,677 centenarians, the highest number in the world, of whom 88% are women. The oldest woman is Kishimoto Fuyo, a 114-year-old from Kyoto City and the oldest man is Kato Hikaru, a 112-year-old from Kumamoto.

Health Minister Kenichiro Ueno said he was "delighted that so many people are living long, healthy and active lives", citing progress in medicine and technology.

But Kenichiro also warned of the challenge the country faces in maintaining a sustainable social security system.

Experts put the long lives of the Japanese down to several factors, including a healthy diet and an active lifestyle.

The island nation's cuisine predominantly consists of fish, vegetables, and rice - and less saturated fat than many Western diets.

Older people also regularly walk, use public transport, cycle and stretch.

Japan has been aging for years and sales of adult nappies have been higher than those for babies for more than a decade.

Companies have also developed new products for the older population, including a powered exoskeleton to support moving various parts of the body and eyewear that automatically adjusts its focus.
