Intrax Then and Now

Founded in 1980

In 1980, founders John Wilhelm and Takeshi Yokota began organizing small groups of Japanese students to come to the U.S. and stay with American host families for two- to four-week homestays. Their mission was to provide both the students and the families with unique and personal connections that would increase cultural understanding and inspire mutual respect and personal growth.

As time went on, the program grew to include other countries and additional cross-cultural experiences. What began as a single program has grown into an ever-expanding family of programs designed to connect people from all over the world.
