One Sided Match Results

    Keywords: Culture & History

Big Seven title matches in which the loser was unable to win any games.

The Kisei, Meijin and Honinbo are best of seven (requiring 4-0); the Tengen, Gosei and Judan are best of five (requiring 3-0). The Oza has also been a best of five since (apparently) 1984, previously a best of three.

The years, since 1964, in which every challenger won at least one game were 1967-68, '71-72, '74, '76, '78, '82-83, '90-92, 2003, '14, '19 and '21.

Iyama Yuta's dominance from 2011 to 2018 can be seen very clearly at the bottom of the table.
