Who We Are

LEX Language Project is a 501(c)(3) nonprofit organization, founded by Japanese educator Yo Sakakibara. The name LEX stands for Language EXperience, EXperiment, and EXchange.

Our History

The history of LEX begins in 1968 with the founding of the Language Research Foundation (LRF) in Cambridge, MA by Yo Sakakibara, LRF was founded with the mission of promoting collaborative research on language acquisition by linguists at local institutions, such as MIT and Harvard. In 1972, Sakakibara developed a partnership with 4-H, a U.S. government-sponsored youth education program, to establish an international exchange program. Sakakibara then came to found the LEX Institute in Tokyo, Japan and the Hippo Family Club, a community-based group focused on promoting language acquisition, in 1981.

LEX Language Project itself was founded in Cambridge, Massachusetts in 1985, mainly to facilitate the LEX exchange programs in the United States. Since then, the organization has developed language clubs modeled after Hippo Family Club to serve communities across the United States. LRF, now a part of LEX Language Project, publishes books on language, mathematics, and the natural sciences.
