In several scenes in the movie, Kaguma-Hime, Lady Sagami and Ona can be seen wearing multi-layered kimonos called Junihitoe. Both the number of layers and the coloring of the layers worn would be dictated by the occasion, status, and season the wearer is in.
The movie's budget was estimated at 5 Billion Yen (US$49.3 million) making this film the most expensive Japanese film produced.
(At around thirty-eight minutes) The scroll which Lady Sagami unrolls for Princess Kaguya, is based on actual scrolls. In 1999, Takahata published a book comparing these twelfth century picture scrolls to cinematic animation.
At two hours and seventeen minutes, this is the longest film by Studio Ghibli, three minutes longer than Princess Mononoke (1997).
In the Heian period, etiquette dictated that a lady could not directly communicate with outsiders. Therefore, during the naming ceremony and when suitors arrive, Kaguya-hime is kept behind a screen (sudare) or blinds, shielded from view.
