This trail is in the Kirifuri Highlands of Nikko in Tochigi Japan. 7.2 km (4.5 mi) after a quick descent to a river crossing, you have a steep climb for 1.7 km that leads to the above downhill. High point is 1218m (2840ft) descend to 645m (1500ft) for a total vertical of 573m (1335ft). The off camber stuff is quite tricky in the snow.
Hard to tell in the video, but there is blood on the trail from a deer kill where the snow gets deep and kills my momentum. Thinking it might be one of my hunter buddies with a fresh kill, I went to his cabin. Unfortunately it wasn't his kill that I came across. Lucky for me though, he did have some wild boar stew on the stove.
