 note = {Currently, German wheat yield is 7.0 t/ha higher than Japanese yields. In this study, we investigated from three perspectives why wheat yield is higher in Germany than in Japan: the characteristics of the wheat farms, cultivation techniques, and regulations on wheat quality classification and marketing. German wheat farmers cultivate wheat efficiently using high-powered machinery in large fields. They manage their farms intensively despite the large scale. Germany's wheat is sold by the quality group. Farmers can sell mixtures of several varieties that are classified in the same quality groups. This marketing system encourages farmers to introduce new varieties with stronger disease resistance and higher yield. In contrast, Japanese farmers manage much smaller fields, have access to small-powered machinery and sell wheat by the varieties due to the marketing regulations. Japanese farmers should consider consolidating their fields to take advantage of economies of scale and should develop new cultivation techniques appropriate for this revised approach. The Japanese government should also look for ways to encourage farmers to introduce new varieties.},
