Kazushige Nagashima (長嶋 一茂,Nagashima Kazushige, born January 26, 1966) is a Japanesetarento, sports commentator and former professionalbaseball player. His father is Japanese baseball legendShigeo Nagashima.

Nagashima was born in Tokyo, Japan, the oldest son of former Japanese national team managerShigeo Nagashima and his wife Akiko.^[1] His brother, Masaoki, is a race car driver, and his sister, Mina, is a newscaster. Nagashima's wife is his business manager, and they have twin daughters.

Nagashima enteredRikkyo University, following his father, and attracted much attention from professional scouts, being the son of Shigeo Nagashima. He was drafted in the first round of the 1988 draft by theYakult Swallows, and his first professional hit was a home run against theYomiuri Giants, and the pitcher wasBill Gullickson. He was touted as the next big star in Japanese baseball, after his father, but failed to live up to expectations. Nagashima did not hit or field well, and his playing time decreased as the years went on. In 1992, he spent a year with theLos Angeles Dodgers single-A team in the United States, but made little improvement.

He was about to be released from the Swallows in 1992, but was traded for money to theYomiuri Giants, where his father was the manager. He did not play any better with the Giants, but his team won the league championship in 1994, and the father-son combination became a pet topic of the Japanese media. Nagashima suffered various injuries to his wrists and ankles during this period, and in 1993, he went to the U.S. to undergo surgery.

Nagashima's baseball career ended in 1996. The team demoted him to the minor leagues, along with a fine and a suspension, when he insulted coachShozo Doi after he was told to practice bunting. Nagashima explained that he had no intention of insulting Doi, but pressure from the team and his own frustration increased when he yelled at Doi for telling him to bunt. Giants ownerTsuneo Watanabe was upset, and managerShigeo Nagashima was forced to tell his son that he would not be offered a contract for next year. Several teams showed interest in signing Nagashima, but he announced his retirement, ending his nine-year career in the professional leagues.

Nagashima had poor relationships with many managers and coaches throughout his career. FormerYomiuri Giants managerTsuneo Horiuchi and formerYakult Swallows managerKatsuya Nomura had particular problems with Nagashima. Horiuchi (a pitching coach while Nagashima was on the Giants) was irritated at Nagashima, who probably spent more time partying than taking batting practice. Nomura criticized Nagashima when he was cut from the Giants, since he was the only player that never took notes when Nomura held daily meetings with the team during spring training.

Nagashima became a sportscaster after retiring, hosting several sports shows from 1997~2002. He appeared on anNHK drama series in 2000, and has starred in several movies since then. His acting is thought to be somewhat better than his ability on the baseball field.

Among his drama appearances was the role of Motorbike Cop Ken Nakajima in "You're under arrest "( Japanese -Taiho Shichauzo )in 2003. This drama was based on a long-running anime series of the same name. In the anime Ken Nakajima is a lovable but slightly oafish character. Nagashima's somewhat broad acting style perfectly suits this role.

He has also appeared as a commentator forK-1 broadcasts, owing to his experience with Kyokushin Karate. He was knocked unconscious when he was put into a mock matchup with former K-1 World Max championMasato on a television show.

He also appears regularly on a quiz game show, and on other variety television shows. He is in several television commercials, including one when he appears alongside his father.

At the beginning of 2005, he was made theYomiuri Giants special advisor, and theYomiuri Shimbun sports advisor. He was given the position with a recommendation fromYomiuri Giants ownerTsuneo Watanabe, showing that the rift between him and his former team has healed over time. This is one of the only instances where a mediocre baseball player was given a high position in the Yomiuri organization. He also ran the first Japanese leg of the2004 Summer Olympics torch relay.^[2]

Nagashima played the voice of "Kōichi", father of the human protagonist inStudio Ghibli's 2008 animated filmPonyo on the Cliff by the Sea.^[3]
