Ichirunonegai (2008)

A man returns to the scene of the disappearance of his son 22 days earlier in the snows of Northern Japan in an attempt to find closure. But he couldn't, in his wildest dreams, imagine what was awaiting him. Is it grief, is it madness, or is he really entering the world of Japanese mythology and Yukionna - the infamous Japanese snow-woman? The border between reality and imagination blur in a magical tale of the power of faith.
