第一次世界大战后，20世纪20 - 30年代，日本对小麦的需求迅速增加，因为大米价格上涨，主食的饮食习惯多样化。因此，三井物产或三菱商事从北美（美国和加拿大）和澳大利亚进口的小麦和面粉迅速扩大。两家公司的西雅图分支从外国农作物出口商和这些地区的主要制粉公司购买小麦和面粉。各分公司迅速地将它们出口到日本或中国。此外，三菱商事试图出口到欧洲，所以该公司面临着激烈的竞争，经销商。

After World War I, in 1920s-1930s, the demand of wheat increased rapidly in Japan, because the rice price rose and the eating habits of the staple food were diversified. Therefore, the import of the wheat and flour from North America (United States and Canada) and Australia by Mitsui-Bussan or Mitsubishi-Shoji expanded rapidly. The Seattle branch of both companies bought wheat and flour, from the foreign crop export dealers and the leading milling companies of these districts. And the branches exported them to Japan or China briskly. Furthermore, Mitsubishi-Shoji tried to export to Europe, so the company faced the severe competitions to the dealers.
