Shigeo Nagashima, Japan’s most celebrated baseball player and a linchpin of the storied Tokyo Yomiuri Giants dynasty of the 1960s and 1970s, died in a Tokyo hospital on Tuesday. He was 89.

He died of pneumonia, according to a joint statement released by the Giants, the Yomiuri Shimbun newspaper and Nagashima’s management company.

A star from his first season in 1958, Nagashima instantly made a splash with his powerful bat, speed on the basepaths and catlike reflexes as a third baseman. He notched numerous batting titles and Most Valuable Player Awards, and he was a key member of the Giants’ heralded “V-9” teams, which won nine consecutive Japan Series titles from 1965 to 1973.

More than any player of his generation, Nagashima symbolized a country that was feverishly rebuilding after World War II and gaining clout as an economic power. Visiting dignitaries sought his company. His good looks and charisma helped make him an attraction; he was considered Japan’s most eligible bachelor until his wedding in 1965, which was broadcast nationally.

The news media tracked Nagashima’s every move. The fact that he played for the Giants, who were owned by the Yomiuri media empire, amplified his exploits. He wore his success and celebrity so comfortably that he became known as “Mr. Giants,” “Mr. Baseball” or, sometimes, simply “Mister.”

“No matter what he did or where he went there was a photo of him — attending a reception for the emperor, or coaching a Little League seminar, or appearing at the premiere of the latest Tom Cruise movie,” Robert Whiting, a longtime chronicler of Japanese baseball, wrote about Nagashima in The Japan Times in 2013. “People joked that he was the real head of state.”

None of that celebrity would have been possible had he not excelled as a ballplayer. Along with his teammate Sadaharu Oh, Japan’s home run king, Nagashima was the centerpiece of the country’s most enduring sports dynasty. He hit 444 home runs, had a lifetime batting average of .305, won six batting titles and five times led the league in runs batted in. He was a five-time most valuable player and was chosen as the league’s top third baseman in each of his 17 seasons. He was inducted into Japan’s Baseball Hall of Fame in 1988.
