In 1976, Dr. Suzuki started the Living Centenarian Study supported by funding from the Japan Ministry of Health, Labour and Welfare. He has visited local residences, mostly homes, for nearly 1,000 centenarians and thousands of younger elders in their seventies, eighties, and nineties. He has clinically examined each individual directly with his own naked eyes.
Dr. Suzuki has over 300 scientific publications in peer-reviewed journals and his total publications number over 700 including scientific manuscripts, conference proceedings, books such as “The Centenarians,” “The Centenarians Science,” “Japanese Centenarians,” and book chapters in an aging and health, especially centenarians research. In 1981, he organized the International 100 Club in Hamburg, Germany. This became the first international multidisciplinary cooperative research group of centenarians. As the first scientist to make a comprehensive study of Okinawan longevity, he organized a conference in 1995 in which the Director of the World Health Organization supported the proclamation of Okinawa as a World Longevity Region.
In 1998, Dr. Suzuki was presented with the Nishinippon News Award to recognize his lifetime contributions to health and wellbeing in Japan.

She has created accessible wellness education programs in both English and Japanese, and has collaborated with local Okinawan farmers and elders to preserve traditional knowledge on food, healing herbs, and daily life rhythms.
Christal’s work draws from lived experience, field research, and interviews with long-lived Okinawan elders and health practitioners. Her focus areas include Okinawan plants and herbs, their components, and Yakuzen medicinal food therapy. She is currently developing an Okinawan ikigai-based discovery framework to help others identify their unique purpose, modeled on the traditional concept of life alignment.
Her writing on Okinawan longevity has been featured in health blogs, community newsletters, and wellness seminars, and her digital resources are used by individuals across Japan and abroad.
