"Princess Mononoke" was produced with an estimated budget of ¥2.35 billion (approximately US$23.5 million). It was mostly hand-drawn, but incorporates some use of computer animation in approximately ten percent of the film. The computer animated parts are designed to blend in and support the traditional cel animation, and are mainly used in images consisting of a mixture of computer generated graphics and traditional drawing. A further 10 minutes uses inked-and-painted, a technique used in all subsequent Studio Ghibli films. Most of the film is colored with traditional paint, based on the color schemes designed by Miyazaki and Michiyo Yasuda. However, producers agreed on the installation of computers to successfully complete the film prior to the Japanese premiere date. Telecom Animation Film Company and Oh! Production helped animate the film. Toei Animation and DR Movie helped with the painting process.
