The study of food and foodways is a field that has until quite recently mostly been neglected as a field of history despite the importance that food plays in culture and as a necessity for life. The study of immigrant foodways and the mixing of and hybridization of foods and foodways that result has been studied even less, although one person has done extensive research on Western influences on the foodways of Japan since 1853. This paper is an attempt to study the how and in what forms the foodways of America-and in particular of Oregon-changed with the arrival of Japanese immigrants beginning in the late-nineteenth century, and how the foodways of the first generation immigrant Japanese-the Issei-did and did not change after their arrival. In a broad sense, this is a study of globalization during an era when globalization was still a slow and uneven process and there were still significant differences between the foodways of America and Japan.
