Saiyūki (, lit. "Journey to the West"), also known by its English title Monkey, also commonly referred to as Monkey Magic (the show's title song), is a Japanese television drama based on the 16th century Chinese novel, Journey to the West, by Wu Cheng'en. Filmed in Northwest China and Inner Mongolia, the show was produced by Nippon TV and International Television Films in association with NHK (Japan Broadcasting Corporation), and broadcast from 1978 to 1980 on Nippon TV.
Two 26-episode seasons ran in Japan: the first season ran from October 1978 to April 1979, and the second one from November 1979 to May 1980, with screenwriters including Mamoru Sasaki, Isao Okishima, Tetsurō Abe, Kei Tasaka, James Miki, Motomu Furuta, Hiroichi Fuse, Yū Tagami, and Fumio Ishimori.
Saiyūki was dubbed into English from 1979, with dialogue written by David Weir. The dubbed version was broadcast under the name Monkey and broadcast in the United Kingdom by the British Broadcasting Corporation, in New Zealand by Television New Zealand and in Australia by the Australian Broadcasting Corporation. Only 39 of the original 52 episodes were originally dubbed and broadcast by the BBC: all 26 of series 1 and 13 of series 2. In 2004, the remaining 13 episodes were dubbed by Fabulous Films Ltd using the original voice acting cast, following a successful release of the English-dubbed series on VHS and DVD; later, these newly dubbed episodes were broadcast by Channel 4 in the UK.
A Spanish-dubbed version of Monkey aired in Mexico, Costa Rica, Peru, Argentina, Uruguay and the Dominican Republic in the early 1980s. While the BBC-dubbed Monkey never received a broadcast in the United States, the original Japanese-language version, Saiyūki, was shown on local Japanese-language television stations in California and Hawaii in the early 1980s.
