Hunter × Hunter
Before the first anime television series was created, a short film adaptation of "Hunter × Hunter" was shown as part of the 1998 "Jump Super Anime Tour" alongside similar adaptations of "Seikimatsu Leader den Takeshi!" and "One Piece". Produced by Studio Pierrot and directed by Noriyuki Abe, it depicts the early events of the manga up to Gon's ocean voyage from Whale Island.
The Heroic Legend of Arslan
It was adapted into a manga, which caught up with the novel and then received an original ending, and ran from November 1991 to September 1996. It also received two anime film adaptations, and a four-part, unfinished anime OVA. In 2013, a second manga adaptation started serializing at "Bessatsu Shōnen Magazine", with illustrations by Hiromu Arakawa. In 2015, it was adapted into an anime television series, which covered Tanaka’s first 4 novels, and was based on Arakawa’s manga art style and character designs. A second season, based on novels 5 and 6, aired in 2016.
