The enduring popularity of professional baseball in Japan finds its roots in the tradition and fervor of the Tokyo Big Six University Baseball League, a collegiate circuit that predates the nation’s professional leagues by over a decade. note reported.
On September 24, 2023, a visit to Meiji Jingu Stadium, the league’s historic home, reveals this atmosphere. The air carries the scent of old dust as fans pass through the stadium gates. On that day, the late innings of a Waseda vs. Meiji game were underway. At the plate stood Hiroki Hirose, then a Keio University slugger known for his intimidating stance like a guardian deity, now with the Fukuoka SoftBank Hawks. On the mound was Shohei Yoshizawa, a lefty from Hosei University who was just beginning to showcase his talent as a senior, now with Toshiba. The scene was filled with a youthful freshness, a space unique to student athletes that professional baseball cannot replicate. The main attraction for many was the subsequent Meiji vs. Waseda matchup, featuring first-round draft pick by the Hanshin Tigers, Nana Sakakibara, starting in center field for Meiji.
A League Forged in History
However, the league’s activities began even earlier. In 1914, a league was organized among Waseda, Keio, and Meiji. The tradition of the "Waseda-Keio" matchup, the league's signature event, started even sooner, with the first game played in 1903. This makes the league 11 years older than the formation of Japan’s professional baseball league in 1936. The league's deep roots are shown by its existence during the Russo-Japanese War (1904-1905).

The league’s significance was cemented in 1926 with the opening of Meiji Jingu Stadium, built with the league’s cooperation. That same year, the league began playing for the East Palace Cup (later known as the Regent’s Cup), a prestigious prize bestowed by the Imperial Household. In 2025, the league celebrated its 100th anniversary with special events, including an all-star game featuring current players and a legendary ceremony with Hall of Famer Koji Yamamoto throwing the ceremonial first pitch at the spring league games.
The Waseda-Keio Rivalry: A Cultural Phenomenon
At the heart of the Big Six league is the Waseda-Keio rivalry, a fixture known simply as the “Waseda-Keio game.” First played in 1903, it has evolved into the league’s main event, traditionally held at the end of the season and responsible for countless dramatic moments. Its popularity is so immense that the league’s official website issues a specific warning: “Regarding the Waseda-Keio game, congestion is expected…” This is due to the legions of fans who flock to the stadium to sing the anthems “Azure Sky” and “Young Blood” in unison.
Early Controversy and National Impact
In 1911, the Asahi Shimbun (then the Tokyo Asahi Shimbun) ran a series titled "Baseball and Its Evils," which lambasted the sport. Critics called baseball a "thief's game" and an "unnecessary exercise," fueled by concerns over excessive fan adoration and players neglecting their studies to focus on the sport. The fervor was so intense that the Waseda-Keio game was indefinitely suspended for about 20 years starting in 1906.
The controversy subsided after counter-arguments from figures like “the father of Japanese baseball,” Isao Abe, and popular writer Shunroku Oyakawa.
Producing National Heroes
The league has been a consistent pipeline of talent for the Japanese national team and professional leagues. A prime example is the 1934 tour of an American all-star team featuring Babe Ruth and Lou Gehrig. The Japanese team that faced them, known as the All-Japan team, was defeated 0-16. However, the Japanese roster was dominated by Big Six alumni. Of the 31 players on the All-Japan team, 19 were from the Big Six universities, and 9 of those would later be inducted into the Japanese Baseball Hall of Fame. The entire coaching staff, including head coach Tadao Iio and managers Taizo Miki and Tokuo Asanuma, were also Big Six graduates. Future Hall of Famers Eiji Sawamura and Victor Starhin, who hoped to attend Keio and Waseda respectively, left high school early to join the team, showcasing the caliber of players the league produced.
Perhaps the most iconic figure to emerge from the Big Six is Shigeo Nagashima. While he joined the Yomiuri Giants in 1958, after the league's founding, his story is inseparable from its legacy. His impact was so monumental that the history of Japanese professional baseball is often viewed in two eras: "before Nagashima" and "after Nagashima." Advanced metrics show his dominance. Using the wRC+ statistic, which measures a hitter's ability to generate runs relative to the league average (set at 100), Nagashima recorded a wRC+ of 196 in his rookie year of 1958. The following year, he posted an incredible 232 wRC+, leading the league. He topped the league in wRC+ for three consecutive seasons.
A Legacy That Defines the Game
By laying this foundation, the Tokyo Big Six League can be seen as the bedrock upon which Japan’s modern baseball passion is built. The league continues to be a vital part of the country’s sporting identity, a living history that produces the stars and stories that captivate fans every spring.
