developed a "Blow-off snow fence" that began to be installed on national roads in 1969, and later the
Hokkaido Development Civil Engineering Research Institute (Currently, Public Works Research Institute Cold Region Civil Engineering Research Institute) researched "Blow-up prevention type snow fence" and installed it in 1978, and further applied "Blow-up prevention type snow fence" to "Blowing-proof snow fence" from 1981 and since 1988. It came to be installed.

10% to 15% of the fence should be left open so that snow does not settle directly under the fence, which would reduce its effective height. Taller fences trap more snow. Taking the height of the fence as one unit, it should be placed thirty-five units or more to windward of the road or building that it is meant to protect. Permanent snow fences can also consist of lines of closely spaced

In Tohoku and
Hokkaido of Japan, especially in areas with strong wind and snow such as the coastal areas of the Sea of Japan and the plains, structures that lead to snow fences called "Yukigakoi" made of reeds, chives, and wooden boards have been made for a long time. Even now, the culture of making

On the other hand, for roads, a structure called a "Blowing pool type snow fence" was studied and installed for the first time in 1961, referring to the wooden Snow fence used all over the world. Then, in 1967, the

As for transportation facilities, wooden fences made on railway lines in the 1880s as a measure against snowstorms began. However, at the beginning, it was difficult to predict where the snowdrift would be formed, and it was not possible to control the snowdrift well, and there was also a fire

of the fence. Thus, snow fences actually cause snow drifts, rather than preventing them. The fences are placed so as to cause snow to drift where it is beneficial, or not harmful so that the snow does not drift onto undesired areas such as roads or among buildings.

In recent
Japanese railways, "Blowing pool type snow fence" and "Blowing-proof snow fence" have been re-evaluated for their usefulness based on the research results and achievements on the road, so they will be used again as railway snow protection measures.
