Sailor Moon season 1

The first season of the Sailor Moon anime television series was produced by Toei Animation and directed by Junichi Sato. It contains a single story arc called "Dark Kingdom" (「ダーク・キングダム」, "Dāku Kingudamu"), which adapts the first 13 chapters of Naoko Takeuchi's Sailor Moon manga over 46 episodes, following the adventures of Usagi Tsukino and the Sailor Guardians. After the magical cat Luna reveals Usagi's true identity as the titular character, Usagi fights to protect the Earth from the Dark Kingdom, an entity which previously destroyed the ancient Moon Kingdom and has returned to steal the mythical Silver Crystal and life energy from humankind to resurrect their overlord Queen Metalia.

The season first ran from March 7, 1992, to February 27, 1993, on TV Asahi in Japan. Eight DVD compilations were released in Japan between May 21 and July 21, 2002, and the series was later released in a remastered edition in two box-sets from December 11, 2009 to January 21, 2010. In the English language adaptation of the series by former licensee DIC Entertainment, the season's 46 episodes were cut down to 40. The episodes were first broadcast on YTV in Canada from August 28 to October 24, 1995, and later had its first-run syndication in the United States from September 11 to November 3, 1995. The first season was later released by ADV Films in a subtitle-only DVD box set in 2003. Eventually, Viz Media re-released the season's episodes on two uncut DVD and Blu-ray compilations on November 11, 2014 and February 10, 2015.

The season uses four pieces of theme music: one opening theme and two closing themes. The opening theme for the whole season is "Moonlight Densetsu" performed by the idol group Dali. "Heart Moving", performed by Misae Takamatsu of Sakura Sakura, is used as the ending theme for the first 26 episodes, and "Princess Moon", performed by Ushio Hashimoto, is used for the remainder of the season. DIC Entertainment made an English-language version of the Japanese opening theme for its adaptation.

Several video games were released to promote the first season of the original Sailor Moon. On December 18, 1992, Angel (a subsidiary company of Bandai), published Sailor Moon for Game Boy, and on August 27, 1993, published Sailor Moon for Super Nintendo Entertainment System. A port for the Sega Mega Drive developed by Arc System Works was released a year later. Also in 1993, Black HCS developed and published a beat 'em up video game called Bishoujo Senshi Sailor Moon: Kessen Dark Kingdom for Sharp X68000. In 1995, Gazelle developed the arcade game Pretty Soldier Sailor Moon, which was published by Banpresto.
