The rice farming in Kitami-shi in the northernmost region of Hokkaido suffered much heavier crop failures due to the low temperature in summer before and after the World War II, compared to the central core region, and the area is more backward in the postwar development of rice farming. Before the War, there was a tendency in which the acreage of rice fields dropped markedly just after the crop failures. However, after the War, in spite of the severe crop failures in 1953, 1954 and 1956, the decrease in acreage of rice fields was little. As the reason, we can point out control of the price of rice by the government, the spread of the system of mutual insurance of rice farming, the improvement of the irrigation facilities, the progress of cultivation techniques, and the insecurity of unirrigated non-rice farming.
The cool summer of 1964 has given slighter damage than in 1954 although the drop of the temperature was almost similar with that of 1964. Thus the rice farming in Kitami-shi has been improved to be more stable.
