Dr. Coles' Supercentenarian Institute
The Gerontology Research Group is delighted to announce the validation of Mrs. Katsugo Tago.
She was born in Japan (Nagano) on Mar. 28, 1910 and is presently living in Japan (Tokyo) at 113 years of age.
Katsugo Tago was born in Nagano Prefecture, Japan, on Mar. 28, 1910. At the time of her 113th birthday in 2023, she was the oldest resident of Tokyo Prefecture.
The case of Mrs. Katsugo Tago was verified by Robert Young, anonymous, and MHLW, Japan, and validated by the Gerontology Research Group on Sept. 16, 2023. At the time of her validation, she was the sixth oldest living person in Japan (after Fusa Tatsumi, Tomiko Itooka, Okagi Hayashi, Tane Matsubara, and Masa Matsumoto), and the oldest living resident of Tokyo Prefecture.
The Gerontology Research Group extends their thanks to the Tago family for the cooperation on the validation process.
Welcome to the Gerontology Research Group (GRG). As a global non-profit scientific organization, we are dedicated to validating ages, recording, and researching supercentenarians — people who are at least 110 years old. With a history spanning 33 years since our founding in 1990, our passion lies in studying and creating knowledge about human longevity, healthy aging, and the lives of the oldest people on earth.
However, our vital research comes with significant costs. Maintaining our website, conducting research, and traveling great distances to meet the supercentenarians crucial to our studies all require substantial funding.
If you are in a position to support our work financially, we would be immensely grateful for your contribution. Your donation, no matter how symbolic, will help us continue our mission to advance the understanding of human longevity and healthy aging.
Thank you for considering supporting the Gerontology Research Group. Together, we can make strides in the field of gerontology and uncover the secrets to a long and healthy life.
