A case study on the effect of Japanese larch (Larix kaempferi Carr.) arable land windbreaks on the reduction of wind damage in Kamioribe District, Shihoro Town, eastern Hokkaido, Japan, is reported. Wind damage occurred on May 8, 2016. Buds of larches were supposed to be just opened, and the leaves on short shoots were still extending at that time. The percentage of severe damage was high on arable lands outside sheltered areas. In contrast, it was low on lands within areas 15 to 20 times the heights of windbreaks leeward to Japanese larch arable land windbreaks. These differences were statistically significant. The results of this study indicate that Japanese larch arable land windbreaks are effective for the reduction of wind damage during the early spring cultivation season, regardless of if its buds are closed or its leaves are not fully extended.
