Imperial Baseball Game Day

What Is Imperial Baseball Game Day?

Every June 25th is "Imperial Baseball Game Day" (天覧試合の日, Tenran Shiai no Hi) in Japan. On June 25, 1959, Emperor Shōwa (昭和天皇, Hirohito) attended a professional baseball game at Kōrakuen Stadium in Tokyo — the first time in history that a reigning Japanese Emperor had watched a professional baseball game. The game — between the Yomiuri Giants and the Hanshin Tigers — has entered baseball legend for its dramatic conclusion: Giants slugger Nagashima Shigeo (長嶋茂雄) hit a sayōnara (walk-off) home run in the final inning in front of the Emperor.

Nagashima's Imperial Home Run

The June 25, 1959 game was tied in the final inning when Yomiuri Giants star Nagashima Shigeo — already one of Japan's most beloved baseball players — came to the plate and hit a walk-off home run to win the game. The moment — a dramatic, decisive hit in front of the Emperor watching his first professional baseball game — became one of Japanese baseball's most celebrated stories. Nagashima later said it was the greatest moment of his playing career.

Nagashima Shigeo: Mr. Giants

Nagashima Shigeo (長嶋茂雄, born 1936) is the most beloved figure in Japanese baseball history — nicknamed "Mr. Giants" and "Mister Baseball" for his extraordinary combination of athletic excellence, charismatic personality, and his identification with the Yomiuri Giants across nearly five decades as player and manager. His combination of hitting skill, fielding excellence, and theatrical flair for the big moment made him baseball's equivalent of a kabuki star — always performing at his best when the stakes were highest.

Baseball and the Emperor

The Emperor's attendance at a baseball game in 1959 was symbolically significant — lending imperial sanction to the sport that had become Japan's most popular athletic pursuit in the postwar period. Baseball (野球, yakyū) had been introduced to Japan in the Meiji era and embraced as a sport that combined Western modernity with Japanese values of discipline, team spirit, and technical excellence. The imperial family's interest in baseball confirmed the sport's deep integration into Japanese national culture.

Fun Facts

• Nagashima's retirement: When Nagashima retired as a player in 1974, his farewell speech — "I, Nagashima, have lived my life brilliantly" — delivered in tears before a packed Kōrakuen Stadium, is considered one of the most emotionally powerful moments in Japanese sports history.
• ON combination: The Yomiuri Giants' legendary "ON combination" — Sadaharu Oh (王貞治, home run king) batting cleanup and Nagashima batting third — defined Japanese baseball in the 1960s and 1970s and produced one of the most feared lineups in professional baseball history.
