Plot
Hanamichi Sakuragi is a delinquent and the leader of a gang. Sakuragi is very unpopular with girls, having been rejected an astonishing fifty times. In his first year at Shohoku High School, he meets Haruko Akagi, the girl of his dreams, and is overjoyed when she is not repulsed or scared of him like all the other girls he has asked out.
Haruko, recognizing Sakuragi's athleticism, introduces him to the Shohoku basketball team. Sakuragi is reluctant to join the team at first, as he has no prior experience in sports and thinks that basketball is a game for losers (in addition to the fact that the fiftieth girl rejected him in favor of a basketball player). Sakuragi, despite his extreme immaturity and fiery temper, proves to be a natural athlete and joins the team, mainly in the hopes of impressing and getting closer to Haruko. Later on, Sakuragi realizes that he has come to actually love the sport, despite having previously played primarily because of his crush on Haruko. Kaede Rukawa — Sakuragi's bitter rival (both in basketball and because Haruko has a massive crush, albeit one-sided, on Rukawa), the star rookie and a "girl magnet" — joins the team at the same time. Not long after, Hisashi Mitsui, a skilled three-point shooter and ex-junior high school MVP, and Ryota Miyagi, a short but fast point guard, both rejoin the team and together these four struggle to fulfill team captain Takenori Akagi's dream of winning the national championship. Together, these misfits gain publicity and the once little-known Shohoku basketball team becomes an all-star contender in Japan.
Production
Inoue became inspired to make Slam Dunk as he liked basketball since his high school years. After Inoue started Slam Dunk, he became surprised while receiving letters from readers that they started playing the sport due to the manga. His editor even told him "basketball was a taboo in this world." Due to these letters, Inoue decided he wanted to draw better basketball games in the series. With the series, Inoue wanted to demonstrate the feelings from an athlete such as their thoughts when they win, lose or improve at their sport. When he started making Vagabond, he noted that when he was doing Slam Dunk he had a simpler perspective on life as he focused more in victories and success.
With the series, Inoue wants the readers to feel achievements as well as love for the sport.Thinking that his success as a manga artist being largely due to basketball, Inoue organized a Slam Dunk Scholarship for Japanese students as he wanted to give back to the sport by increasing its popularity in Japan.However, when asked about the response from readers to basketball, Inoue commented that although Slam Dunk is technically a basketball manga, its story could have been done with other sports such as soccer. He also added that the artwork for the manga was very typical and mangalike in comparison to his newer works such as Real. His experiences with basketball also influenced the story from Slam Dunk: as a youth Inoue started playing basketball to be popular with the girls, but later became interested with the sport in and of itself. This was mirrored in the character of Hanamichi Sakuragi, who starts playing basketball to be popular with the girl he likes, to later become truly fond of the game.
