KOGANEI, Japan - The master of animation Hayao Miyazaki has revealed that his new short film is about a tiny hairy caterpillar and will be his first fully computer-generated film.

In a rare public appearance in his office in Tokyo's western suburbs, Miyazaki told foreign journalists Monday that the new film is for screening at the Ghibli Museum and is planned for completion in about three years.

Miyazaki said he wants to focus on the basics of life over millions of years instead of short spans of history.

Miyazaki, one of animation's most admired and successful directors and co-founder of Studio Ghibli, won an Oscar in 2003 for his masterful, disturbing critique of modern industrialism in "Spirited Away." He announced his retirement from feature-length films in 2013.
