Ultimately it's a snowboarding film [Fourth Phase], of course, so the main thing that we wanted to celebrate was how awesome snowboarding is! Secondly, we wanted to celebrate the environment that we all shape our lives around. So the film documents myself and other like-minded individuals attempting to follow the hydrological cycles that shape the worlds we've committed our lives to.

I've been to Japan so many times, but I still constantly stumble across things that are so foreign to me.

I love to snowboard with no cameras: 100 percent.

I realized pretty quickly just how big and aggressive some of the mountains were down in Nagano Prefecture.

I think it mostly comes down to trying to align with people who are down with a mission and will bring optimism.

Apart from those other riders there is a whole production team [ of The Fourth Phase] behind the cameras too, hauling hundreds of kilos of fragile and awkward filming equipment up those same frozen landscapes. They're the real heroes.
