Satoko Okudera

is a Japanese screenwriter. She is known for her screenplays in both live-action and anime media. Her 1995 screenplay for School Ghost Stories was nominated for the Japan Academy Film Prize. She is best known for her collaborations with anime director Mamoru Hosoda.

Career A graduate of the Literature Department of Tokai University in Tokyo, Okudera did not originally consider a career in screenwriting. Instead, she worked for an oil company until 1991, after which she quit her job and became a full-time writer. After over a decade of work in live-action film and television, Okudera was offered her first animation project: adapting Yasutaka Tsutsui's novel The Girl Who Leapt Through Time for director Mamoru Hosoda. The resulting film received worldwide acclaim and gave her international recognition upon its release in 2006. Okudera again collaborated with Hosoda on his 2009 and 2012 films Summer Wars and Wolf Children.
