There was a big slide on Norikura, above Tsugaike, (presumably) on the morning of Monday 14th January.

Click on Hakuba Daily Report for the info.

It was not triggered by a human, and didn't hit anyone, as it probably went off first thing in the morning, but it was big - 200m wide at the top, and funnelled down through a quite narrow run-out for nearly a kilometer, all the way to the flat you exit over, near the hut.

It's the slope you can see from the valley.

Windslab on rain crust on lee slope, so be careful on South (and East and West) facing slopes in Hakuba for a while.

Be careful on North facing too, as the N faces of Happo looked totally wind-scoured ice/rain crust.

Be careful crossing the road too, though, whether facing North or South.

Thanks AK.
fyi, pic of the slide is out there if you do a search.
convex roll was probably the sweet spot.
