From the very first stages of the Company’s business relations, Mitsui & Co. ( U.S.A.), Inc. (Mitsui USA, incorporated in 1966 in New York) has well established itself as a good corporate U.S. citizen through its CSR (Corporate Social Responsibility) programs.

By 1972 the Company was developing its cross-cultural roots and endeavors specifically with organizations such as: The Japanese American Association of New York, which provides assistance with immigration and medical referrals, and supports a much needed seniors’ social network; Music From Japan, featuring music which depicts the diverse state of contemporary Japan; and International House of New York City, a residence for more than 700 graduate students living and interacting together from about 100 countries.

By the early 1980s, Mitsui USA extended its support to the arts and New York cultural institutions, such as The Metropolitan Opera.

By the mid 1980s, with its emphasis on education, Mitsui USA’s corporate giving found its focus with "named" programs such as "Mitsui USA Fellows-In-Residence" and "Mitsui USA Forums" on a number of U.S. university and college campuses, geared to encourage international understanding and U.S.-Japan relations.

In 1987, a Mitsui USA foundation was established, and in 1989 The Mitsui USA Foundation was fully operational as the charitable arm for Mitsui USA’s CSR or good corporate citizenship.
