The first Functional Forum in Japan

Join James Maskell and leading luminaries from the American functional medicine community for a cultural exchange like no other — three days of clinical depth, Japanese hospitality, and cross-pollination between two of the world's most promising health traditions.

Explore the journey

The premise

Japan is brilliant at public health. We're brilliant at personalisation.

Japan has built one of the healthiest populations on earth through diet, community, and public health — but the country is still discovering the granular, personalised tools of root-cause medicine. The American functional medicine community has the opposite story. This journey is the place those two worlds meet, learn from each other, and leave changed.

The journey

Three days. Two traditions. One unforgettable exchange.
