Okay, so he's not just in Niseko, or even Japan, but Antti filmed a large part of this awesome edit in Hokkaido. The bigger alpine stuff was obviously shot elsewhere, but a lot of the pillows, drops and awesome face-shots were filmed up North somewhere close by.
Right from the first shred shot where Antti butters off a drop and has to wipe the pow from his face before his next slash, you know this is going to be a good watch. Its fast paced, fun and has a few tech tricks to balance all of the pow shredding.
All in all its a video worth watching... and sharing!
