Takehiko Inoue is a Japanese manga artist, writer, and director born on January 12, 1967, in Okuchi, Kagoshima. He developed an early interest in drawing and was an active basketball player during his school years, an experience that would later define much of his creative output. After studying literature at Kumamoto University, he left to pursue a career in manga, first working as an assistant to Tsukasa Hojo, creator of City Hunter, before making his debut in 1988 with Purple Kaede, which won the Tezuka Award.

Inoue gained widespread fame with Slam Dunk, serialized in Weekly Shonen Jump from 1990 to 1996. The series follows Hanamichi Sakuragi, a delinquent who joins his high school basketball team. It became one of the best-selling manga series in history with over 170 million copies sold worldwide and received the Shogakukan Manga Award in 1995. Slam Dunk was adapted into a 101-episode anime television series and four films. The manga is credited with popularizing basketball among Japanese youth, and in 2010, Inoue received a commendation from the Japan Basketball Association for his contribution to the sport. He and his publisher later established the Slam Dunk Scholarship program to support young Japanese basketball players studying in the United States.

Buzzer Beater, another basketball-themed work, began as an early example of a web comic when Inoue launched it online in May 1996 on the Sports-i ESPN website before it was also serialized in Monthly Shonen Jump. The story follows a team from Earth competing in an intergalactic basketball league. It was adapted into two anime television series produced by TMS Entertainment, with the first season airing in 2005 and the second in 2007, both supervised by Inoue.

In 1998, Inoue began Vagabond, a fictionalized retelling of the life of legendary samurai Miyamoto Musashi based on Eiji Yoshikawa's novel. The series, which features increasingly expressive brushwork, earned the Kodansha Manga Award in 2000 and the Tezuka Osamu Cultural Prize in 2002. While still working on Vagabond, he launched Real in 1999, a manga about wheelchair basketball that received an Excellence Prize at the Japan Media Arts Festival in 2001.

In 2022, Inoue made his directorial debut with The First Slam Dunk, a feature film adaptation of his original Slam Dunk manga. He also wrote the screenplay and story for the film, which was produced by Toei Animation and became a critical and commercial success. The film won the Japan Academy Prize for Best Animation of the Year, and Inoue received awards for Best Director and Best Screenplay at the Tokyo Anime Award Festival in 2024.

Throughout his career, Inoue has pursued projects beyond serialized manga. He created character designs for the Xbox 360 role-playing game Lost Odyssey and published an illustrated travel memoir titled Pepita: Takehiko Inoue Meets Gaudi in 2013, documenting his reflections on the architect's work in Barcelona. His artistic identity is characterized by a commitment to realism and expressive draftsmanship. In interviews, he has described studying nature and observing athletes firsthand, such as attending a Paralympic game to accurately depict wheelchair basketball players for Real. He has also spoken about becoming deeply immersed in his characters, often unconsciously mirroring their expressions as he draws.

Inoue's body of work holds significant industry standing for both its commercial success and its artistic merit. His series rank among the best-selling manga of all time, and his evolution from sports comedy to historical drama and literary adaptation demonstrates a sustained exploration of human perseverance and physicality. His role as both creator and director on The First Slam Dunk further established his influence as an auteur within the anime industry.
