Kewpie’s origins trace back to the years following World War I, with the founding of Nakishamato Corporation by Toichiro Nakashima (alternately spelled as Nakajima) in 1918. Nakashima had served as an intern for Japan’s Department of Agriculture and Commerce, and had been sent to study food production techniques in the United States and Europe. Returning to Japan, Nakashima decided to apply the canning, production, and marketing techniques he had learned to the Japanese market. In 1919, Nakashima founded a food production company, Shokuhin Kogyo Co.
…In the early 1920s, however, Nakashima traveled to the United States, bringing back a jar of mayonnaise. Until then, mayonnaise had been unknown in Japan. Nakashima recognized, however, that he could adapt the spread for the Japanese market–notably by increasing the proportion of egg yolk in the recipe. The company began marketing its mayonnaise in 1925, adopting the name “Kewpie” after the popular doll created by artist and illustrator Rosie O’Neill.
Kewpie began experimenting with packaging in the 1950s, releasing its first squeezable mayonnaise container in 1958.
1982: The company forms the U.S. subsidiary Q&B and begins selling Kewpie mayonnaise in the United States.
