Measures against Snow and Ice
We take measures against snow and ice to ensure a safe, winter traffic environment, as many parts of the area we cover encounter severe winter weather. In FY2015, our total snow-removal distance reached about 430,000 km (equivalent to travelling approximately 11 times around the earth).

Active Use of New Technologies
To effectively control snow and ice, we actively use new technologies, such as the introduction of GPS vehicle location management systems to stay updated on positions and work details as well as a snowfall measuring WEB system to gather measured data automatically, sharing it internally.
