Summary: A successful but bored accountant in Tokyo is enamored by a beautiful woman gazing out of a dance studio window. Dancing and public display of affection are shameful in Japanese society. But his desire to meet the woman propels him to break societal norms. He starts taking lessons for western dance styles like waltz. He hides his new found passion from his wife and teenage daughter. Soon, his attraction for the woman in the dance studio becomes secondary and he starts enjoying dance for its own sake. It brings him great joy and freedom.
The movie is not a classic but lovely. What's lovely? Each character in the story: the worker, his wife, his daughter, his dance teacher, the girl he is attracted to, his office colleague and a private detective — each person is kind hearted and forgiving.
