- This is the last major animated motion picture to be filmed on plastic animation cels.
- Director 宫崎骏 personally corrected or redrew more than 80,000 of the film's 144,000 animation cels.
- When 哈维·韦恩斯坦 obtained the North-American distribution rights to Princess Mononoke, he approached director 宫崎骏 and insisted on a shorter version of the film that would be better attuned to American audiences. However, Miyazaki was still so upset by the heavily cut version of his 风之谷 (1984) (released as 'Warriors of the Wind') that he angrily left the meeting. Several days later, Studio Ghibli producer 铃木敏夫 sent a katana sword to Weinstein's office with 'NO CUTS' embedded into its blade. The film was later released in the USA in its uncut version. When asked about the incident in an interview, Miyazaki simply smiled and stated "I defeated him".
