List of InuYasha episodes (season 1)

The first season of the anime series InuYasha aired in Japan on Animax from October 16, 2000 through May 21, 2001. Based on the manga series of the same title by Rumiko Takahashi, the episodes were produced by Sunrise and directed by Masashi Ikeda. The series follows a high school girl, Kagome Higurashi who travels back in time to the Sengoku period of Japan where she meets a half-demon named InuYasha and learns that she is the reincarnation of a powerful priestess named Kikyo. Joined by a lecherous monk, a young fox demon, a demon slayer, and a demon cat, the group seeks to find the fragments of the shattered Jewel of Four Souls, a powerful jewel that had been hidden inside Kagome's body, and keep the shards from being used for evil, including the evil half-demon Naraku who slew Kikyo fifty years before Kagome's arrival. The first season introduces the central characters and shows the group gathering together.

The anime is licensed for release in North America by Viz Media. The English dub of the first season was broadcast on Cartoon Network as part of its Adult Swim programming block from August 31, 2002 through January 21, 2003. The first season was released on nine DVD compilations by Viz Media. A full box set containing all twenty-seven episodes was released on September 7, 2004.
