Goodbye for Tomorrow (1995)

People from all walks of life (a high-school student, a middle-aged businessman, a yakuza chief, etc.) all receive mysterious messages from loved ones who were killed 3 months earlier in a shipwreck. They are instructed to go to a small island in the Inland Sea that evening. At the stroke of midnight, the lost ship emerges from the sea and they are given a brief time to say their final words to their lost loved ones, before the deceased must once again board the ship and it sinks back into the depths.
