Sumitomo Life announced that the Tokyo Green Biz Walk, conducted in partnership with the Tokyo Metropolitan Government, has exceeded 38,000 participants as of October 26, 2026. The project encourages health promotion and the experience of the allure of greenery through walking around lush spots in Tokyo. The total number of participants in the Vitality Walk has surpassed 140,000 nationwide.
Sumitomo Life introduced the "Vitality AI Chat" utilizing generative AI in October 2026. By narrowing down inquiries through additional questions and providing answers within a pre-prepared FAQ range, the service enhances convenience while mitigating hallucination risks. As of the end of March 2026, there were approximately 2.4 million Vitality members, and the goal is to expand to 5 million by 2030, advancing support that combines humans, AI, and digital technology.
Sumitomo Life, as the first step in concretizing the 'Wellbeing Co-Creation Value', estimated the social value generated by health promotion for approximately 1.6 million Vitality members at about 410 billion yen per year. The value includes monetary conversions of improvements in subjective wellbeing, labor value, and contributions to medical cost suppression.
Sumitomo Life will collaborate with the Tokyo Metropolitan Government and implement the "Tokyo Green Biz Walk" starting from October 19, 2026. By utilizing part of the Vitality health program, the walk will encourage residents to explore green spots within Tokyo, promoting health creation and experiencing the allure of Tokyo's greenery.
