An ice bridge rises up from Lake Suwa, connecting its opposite shores. Local people have documented this omiwatari or "the God's Crossing," for hundreds of years. But changing weather patterns have taken their toll. The chief priest and parishioners from Yatsurugi Shrine came to the lake in winter to pray for its appearance and to add to a centuries-old record. This film focuses on the people who are struggling to carry on a 580-year-old ritual and others who are learning from their knowledge.
