Tatsuo and Emiko Honma were the founders of, and the driving forces behind, the innovative Tokyo-Frost Valley YMCA Partnership formed with D. Halbe Brown in 1979.

The primary goal of the partnership was to ensure mutual understanding between the peoples of the United States and Japan, providing young people the opportunity to become global citizens with the skills and intention to serve others.

Its programs continue today to support Japanese families living in the United States, offering opportunities for fellowship and helping them cope with the challenges of adapting to a new culture while maintaining a sense of their home culture.
