In shogi, the Bishop Head Pawn or Bishop's Head Pawn Push (角頭歩 kakutōfu or 角頭歩突き kakutō fuzuki) is a surprise opening.[1]

The opening is characterized by advancing early in the game the bishop's head pawn on 8g to 8f if played by Black or on 2c to 2d if played by White, in which it is undefended. This is a daring move since the head of the bishop (the 8g or 2c square) needs to be defended from a Static Rook attack and moving the bishop's head pawn forward increases the vulnerability of the bishop's head.

It can be developed into a Ranging Rook position and is played against a Static Rook position.

The opening was used by professional Kunio Yonenaga (米長邦雄) in tournament play in the 1960s and 1970s.
