Chiyo Miyako — Japanese supercentenarian and world's oldest living person in 2018

Early life and background

Miyako was born in the early 20th century in Kanagawa Prefecture, a region near Tokyo. Like many people who live past 110, the public record of her early life is limited in the popular press, and most accounts focus on her age and recognition rather than a detailed biography. Japan has one of the highest proportions of centenarians in the world, and Miyako's life spanned major historical changes in her country, from the Meiji and Taisho eras through the 21st century.

Recognition and verification

When Nabi Tajima, the previous oldest living person, died in April 2018, Miyako was recognized in news reports as the new oldest living person. Age claims at these extremes are typically checked against civil records and subject to verification by age-research organizations; such verification is important to maintain reliable lists and to distinguish between verified supercentenarians and unconfirmed claims.

Longevity context and lifestyle

Discussion around Miyako's longevity often reflects broader themes: genetics, diet, social ties, and access to healthcare. While individual cases are notable, researchers emphasize that multiple factors contribute to longevity. In Japan, regional diets, public health systems, and community structures have been cited as contributors to the country’s high number of centenarians.

Notable facts

• She became the world’s oldest verified living person after Nabi Tajima died on 21 April 2018.
• Miyako’s lifespan of 117 years placed her among a small group of people worldwide who have reached ages well beyond 110.

Death and legacy

Miyako died on 22 July 2018. Her brief tenure as the world’s oldest living person highlighted public interest in supercentenarians and prompted reflections on aging and long life. Records of such individuals are used by demographers and gerontologists to study human longevity, to document patterns of survival, and to honor lives that span three centuries of social and technological change.
