Top League Champions Cup

The Top League Championship is Japan's highest-level knockout tournament for rugby union clubs.

Held annually, the leading teams from the Top League regular season qualify for the playoffs to decide the Cup title.

The number of teams was also cut to four to give a format of two semi-finals and a final, and from that time onward until the 2016–17 season the winner of the knockout cup was recognised as the Top League champion.

^ The 2004 Kobe Steel and Sanyo (Panasonic) semi-final appearances are included, although that cup was not part of the championship.

The All-Japan Championship doubled as the Top League Champions Cup title from 2018 onward, with university teams excluded.

[13] ^β The number of tries and goals being equal, the result was decided in favour of Yamaha over Toyota by a lottery at Hanazono after the game.
