In 'The Wind Rises', what is the name of the aeronautical engineer protagonist?

In 'The Wind Rises', the aeronautical engineer protagonist is Jiro Horikoshi.

The 2013 Studio Ghibli film, written and directed by Hayao Miyazaki, fictionalizes the life and career of the real Japanese aircraft designer Jiro Horikoshi. The story follows his ambition to create beautiful aircraft, beginning with his university studies and leading to work at Mitsubishi.

Jiro is not the same person as Giovanni Battista Caproni, the Italian designer who appears in his recurring dreams and encourages him to build planes rather than fly them. Castorp is a German character, while Nahoko Satomi is Jiro's fictional romantic partner, inspired partly by Tatsuo Hori's writing.

The film's historical thread culminates in the Mitsubishi Ka-14's test flight in 1935 and later connects Jiro with the A6M Zero fighter. Although the movie depicts real aviation history, its romance and dream encounters are fictionalized.
