When the mountain edge emits light -土砂崩れ編-

砂災害の修復工事。国土の約70％が山地で占められており、連なる火山帯を多く保持している日本は急勾配な斜面が多く大変険しい地形となっている。そのため大きな地震や大雨や台風によって土砂災害や洪水などの自然災害が発生しやすい。 Japanese mountains have rugged topography with a steep slope due to many volcanic chains spread throughout Japan. Therefore, landslide and falling rocks tend to occur frequently by earthquakes and typhoons. This is a repair working in the rugged mountains due to landslide disasters of typhoons.

大きな地震や大雨や台風による落石や土砂の崩壊を防ぐためにあらゆる斜面には擁壁が建設されている。 The mountains occupy about 70% of the land in Japan and the roads construct among its mountains. Therefore, Retaining walls (revetment) are constructed on the slope everywhere in the mountain road in Japan to prevent an accident by falling rocks and landslide by earthquake or typhoon.
