Founded in Japan over 100 years ago in 1919, Kewpie is the company that introduced mayonnaise to Japan. Kewpie first produced and marketed mayonnaise to Japanese customers in 1925 and has been making it ever since with a small stop in production during World War II due to supply shortages. Thanks to Kewpie, mayonnaise is now one of Japan's most popular condiments. Q&B Foods handles the American distribution of Kewpie products. Q&B Foods started out manufacturing Kewpie mayonnaise on a small scale, primarily for use in restaurants.
