JUNE 1, 2025 — Jingu Mae Stadium, Tokyo: Under a warm afternoon sky, history is unfolding. Today marks the 100th anniversary of the Tokyo Big 6 Baseball League, a symbol of enduring rivalry, cultural pride, and youthful spirit. Thousands have gathered at the iconic Jingu Mae Stadium to witness the highly anticipated final between Waseda University and Keio University — two of Japan’s most prestigious academic institutions and fierce sports rivals.

With the first pitch scheduled for 13:00, the stadium is already buzzing with energy. The final promises to be not only a celebration of sport but a reflection of a century-long tradition that has shaped student life, university culture, and baseball fandom in Japan. Fans draped in school colors, waving flags, and chanting in unison fill every corner of the stands. The legacy of the Big 6 lives in every cheer, every hopeful face, and every echo reverberating from the field.

This is no ordinary game. It’s a culmination of legacies built over decades. The Waseda-Keio rivalry — known as “Sōkeisen” — is as much about history as it is about baseball. While Waseda supporters voice confidence in a victory, Keio’s faithful are equally optimistic, making this final a clash not just of skill, but of pride and tradition.

With only 25 minutes remaining before the game begins, anticipation is at its peak. The stakes are high, the atmosphere electric. Who will claim glory on this historic day? No one can say. But one thing is certain — this game, this moment, this centennial celebration will be remembered for generations to come
