And here's the longer Japanese trailer.
The Wind Rises (風立ちぬ Kaze Tachinu) is a 2013 Japanese animated historical fantasy film written and directed by Hayao Miyazaki.[2] The film is based on the manga of the same name, which is in turn based on a short story by Tatsuo Hori, a writer, poet and translator from mid-20th century (Showa period) Japan. Kaze Tachinu is a fictionalised biography of Jiro Horikoshi, designer of the Mitsubishi A5M (featured in the movie) and its famous successor, the Mitsubishi A6M Zero. Both were fighter aircraft that the Empire of Japan used in World War II.
The Wind Rises gets a limited release in the US starting February 21st, 2014, expanding a week after, in addition to the awards qualifying run in New York and Los Angeles from November 8th-14th.
