The downward displacement in stomach cancer mortality among Japanese migrants to the United States and their descendants provides an opportunity to see whether the changes in risk can be associated with changes in customs, occupation or other environmental exposures traceable to migration. Case­ control studies in two prefectures of Japan and in Hawaii and California undertaken with this objective in mind are described. Some preliminary results from interviewing in Miyagi prefecture on the association of selected items of diet with stomach cancer are presented and discussed. References ArRD, 1., BENTALL, H.
