In a statement from the Yomiuri Giants, it was confirmed that Nagashima succumbed to pneumonia while in a Tokyo hospital. He was a luminary in Japan's sports landscape, remembered not only for his exceptional skills, which included hitting 444 home runs over 2,186 games, but also for the charm and charisma he brought to the game. His on-field triumphs spanned the 1960s and 70s, capturing the imagination of a nation experiencing economic growth and newfound confidence.

The government recognized Nagashima's contributions, with a spokesman noting that he provided "bright dreams and hopes" for many. Fellow baseball icon Sadaharu Oh expressed heartfelt gratitude for the opportunity to play alongside him, while current star Shohei Ohtani shared nostalgic moments on social media, honoring Nagashima's impact on the sport.

Nagashima made history by hitting a decisive home run during the first professional baseball game attended by the Japanese emperor in 1959. He enjoyed a remarkable 17-year playing career, earning the Central League batting title six times and later leading the Giants to two Japan Series championships as a manager.

Chief Cabinet Secretary Yoshimasa Hayashi celebrated Nagashima as a "sunny person" and acknowledged the indelible marks he left on Japanese professional baseball and society as a whole. His legacy will continue to inspire future generations, as his life was full of achievement and joy.
