The Ishida Opening (石田流三間飛車 ishida-ryū sankenbisha or shorter form 石田流 ishida-ryū) is a major variation in Third File Rook openings of the Japanese game of shōgi.

In the Ishida Opening, in contrast to other Third File Rook openings, the seventh file pawn is advanced to the fifth rank if played by Black (P-75), or the third file pawn if played by White (P-35). This allows the rook to move up to the 76 square (Black) or 34 square (White).
