HLMC2026 is the 2nd Healthy Longevity & Medicine Conference, building on the inaugural meeting held at the National University of Singapore in 2025. This year it comes to Tokyo (Juntendo University, 18–20 November 2026) as a hybrid conference under the theme "Quantifying Aging: AI and Aging Clocks in Precision Health". Across academic sessions, an industry partnership programme, and young-scientist sessions, we welcome work in geroscience, clinical longevity, regenerative medicine, and precision health.
