Okisaki shogi (御妃将棋 okisaki shōgi "Queen shogi") is a modern variant of shogi (Japanese chess). It was developed by Masayuki Nakayachi c. 1996 from suggestions by German chess player Ralph Blockhaus.

Okisaki shogi is similar to standard shogi, but is played on a 10×10 board. There are ten pawns and a queen, which moves like a queen in Western chess. The knights also move as in Western chess.

Rules of the game[edit]


The objective of the game is to capture your opponent's king or all other pieces.[citation needed]

Game equipment[edit]

Each player has a set of 22 wedge-shaped pieces: those of standard shogi plus a queen and an extra pawn. The queen is placed to the immediate left of the king.


Piece moves are as in standard shogi, apart from the queen (妃将 or 妃 hishō or okisaki "princess") and the knights (跳馬 or 跳 chōma), which move as in Western chess, and the lance, which can move directly forward or backwards (standard shogi knights and lances can only move forward.)

Because they can back out, the standard requirements for promoting knights and lances in the final ranks, and restrictions on dropping them there, do not apply to okisaki shogi. Limits on pawn drops are as in standard shogi.


Pieces other than the king, queen, and gold promote as in standard shogi.
