“Mom, are you happy with him? Father said nothing and died quietly.” Hiroshi finds a short message that his sister Maki had written to the mother who abandoned them eighteen years ago. Their father has recently died of a heart attack, without talking about his divorce. Hiroshi decides to search for his mother, and tracks her down to a bar in the Ginza district of Tokyo. They become close, as though they had never been separated. However, Maki is upset and outraged as she finds her in Hiroshi’s apartment.
The idea of the film was sparked by a single message included in a book entitled Japan’s Best “Short Letters to Mom”, which became a surprise best-seller. The episodic narration constructs a story around this message out of a combination of flashbacks and parallel scenes.
