I definitely recommend Tokyo Godfathers, which is a wonderful remake of John Ford's The Three Godfathers.
Three homeless people find a baby on Christmas Eve, and decide to find the mother. There is a drunk who left his family, a teen-age girl who ran away, and a drag queen.
This is a PG-13 film, as there is some violence, a bit of language, and some non-PC comments directed to the drag queen (or from him.) There is also a breast in a non-sexual situation.
This is only Japanese language, with English subtitles.
