Satoko Okudera (奥寺 佐渡子 Okudera Satoko, born 1966 in Iwate Prefecture) is a Japanese screenwriter. She is known for her screenplays in both the live-action and anime mediums. Her 1995 screenplay for Gakkō no kaidan was nominated for the Japan Academy Prize. She is best known for her collaborations with anime director Mamoru Hosoda. 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 Toki o Kakeru Shōjo for director Mamoru Hosoda. The resulting film, The Girl Who Leapt Through Time, received worldwide acclaim and gave her international recognition upon its release in 2006. Okudera again collaborated with Hosoda on the 2009 film Summer Wars. At the 2009 Anime Festival Asia in Singapore, Hosoda revealed Okudera would be writing the script for his next project, Wolf Children.
