Many of the most popular shōnen manga titles have been serialized in Jump, including Dragon Ball, Captain Tsubasa, Slam Dunk, One Piece, Demon Slayer: Kimetsu no Yaiba, My Hero Academia, Yu-Gi-Oh!, Naruto, Bleach, Death Note, Yu Yu Hakusho, Shaman King, Hunter x Hunter, Saint Seiya, Black Clover, JoJo's Bizarre Adventure, and others. With the relaxation of censorship in Japan in the 1990s, a wide variety of explicit sexual themes appeared in manga intended for male readers, and correspondingly occur in English translations. However, in 2010 the Tokyo Metropolitan Government passed the controversial Bill 156 to restrict harmful content despite opposition by many authors and publishers in the manga industry. Modern shōnen manga īuronson and Tetsuo Hara's Fist of the North Star (1983–1988) and Akira Toriyama's Dragon Ball (1984–1995) are credited with setting the trends of popular shōnen manga from the 1980s onwards. In turn, both series were influenced by the martial arts films of Hong Kong action cinema, particularly 1970s kung fu films such as Bruce Lee's Enter the Dragon (1973) and Jackie Chan's Drunken Master (1978).
