The Japanese movie trailer said “13 years since Nausicaa”. Why?
Because “Mononoke Hime” is very close to Nausicaa in terms of its genre (action adventure story) and its theme (the relationship between humans and nature). Miyazaki wasn’t satisfied with the ending of the movie “Nausicaa”, which needed a miracle to bring a happy ending to solve the conflict between humans and nature. So he took another 10 years pursuing this issue (the relationship between nature and man), writing the manga “Nausicaa”, which he finally concluded in 1994. “Mononoke Hime” was based on this conclusion: “there is no happy ending to the fight between humans and Raging Gods” (from the project proposal).
