Here’s a rather detailed synopsis of the plot:
One evening when Akio comes back home from work, his outer, lonesome reality clashes with his inner world filled with precious memories and persons from his life. In his kitchen he meets with a women, a child, and an old man. Just as sudden, a cherry tree, a koi fish and a little pond appear, only to disappear little later. At the climax, the limited space of his kitchen breaks open and Akio finds himself at a seashore. Here, the peace he couldn’t seem to find in his everyday life lies right before him.
