Japan has, for the first time, surpassed the 100,000 mark for centenarians. According to data published in September 2026 by the Japanese Ministry of Health, the country now has 107,677 people aged 100 or over, of whom 94,298 are women – nearly 88 per cent. In 1963, there were just 153.

This exceptional longevity is set against a backdrop characterised in particular by a relatively healthy diet, low rates of obesity, a universal healthcare system and regular physical activity. The Japanese Ministry also highlights improvements in living conditions, diet and nutrition, as well as medical advances.

A simple and varied diet

The traditional Japanese breakfast often consists of a savoury and varied meal: rice, fish or another source of protein, soup, vegetables and fermented foods. This combination allows for a mix of different food groups rather than relying mainly on very sweet or ultra-processed products. However, no single food or meal can, on its own, explain longevity. Dietary habits must be considered as part of a wider picture, alongside physical activity, sleep, healthcare and living conditions.

Staying active and socially connected

Japanese longevity also highlights the importance of staying active on a daily basis. Walking, gentle exercise and group activities help to maintain mobility and social interaction.

Concepts such as ikigai, often associated with a sense of purpose, and community support networks also illustrate the importance of social connections as we age.

The Japanese model is therefore not a magic formula, but it highlights a key idea: ageing well is achieved through a set of health-promoting habits practised throughout one’s life.
