I have noticed a bit of a push from the korean snowfields this year trying to get a slice of the Australians going to japan market. If you can post up some location reviews and vids of yourself riding in Korea (South Korea I assume!)
Do you get the same light powder snow that Japan gets?
As far as I know, the snow condition in Japan is generally better than Korea.
Per conversation with my friend, usually it is bit icy most of the time in Korea (and very crowded).
Nevertheless, there are many exceptional snowboarders in Korea.
Anyway, what I've noticed so far is that there are huge number of Never Summer fanatics in this forum.
