Namida tsubo (2008)

A loving couple should live their lives happily until their golden years. It is not always so. When a magazine editor's wife dies due to cancer, he does the traditional and usual thing. He cremates her body, places the ashes in a white jar and hold on to it admiringly. As time passes the dead wife's sister and her former husband grow closer and end up dating. He is unsure whether he is doing the right thing.
