Shogi rules: how to play Japanese chess
Every rule of shogi with diagrams: how the eight pieces move, the promotion zone, and above all the drop rule — captured pieces change sides — plus nifu, uchifuzume, repetition and impasse.
The short answer
- Shogi is played on a 9×9 board with twenty pieces each, all the same colour — direction shows ownership.
- Captured pieces go into your hand and may be dropped back onto the board as your own.
- Pieces promote by moving into, within or out of the three ranks furthest from you.
- You may not have two unpromoted pawns on a file, and you may not checkmate with a dropped pawn.
- Perpetual check loses, and impasse games are settled on a material count.
The board, the pieces and the promotion zones
Shogi is Japanese chess, and it is the most dynamic member of the chess family for one reason: captured pieces change sides. Nothing ever leaves the game. A piece you take goes into your hand, and instead of moving you may drop it back onto the board as your own.
- Board: 9×9 squares, undifferentiated — no colours.
- Pieces: twenty each, all the same colour. Which way a piece points shows whose it is.
- Black (sente) moves first. The names are conventional; there is no colour difference.
- Promotion zone: the three ranks furthest from you.
How the pieces move
Eight piece types, and only two of them — the rook and the bishop — move any distance. Everything else is short-range, which is why shogi games are slower to develop and far bloodier at the end than chess games.
| 漢字 | Piece | Qty | Movement |
|---|---|---|---|
| 玉 / 王 | King | 1 | One square in any direction. |
| 飛 | Rook | 1 | Any distance orthogonally. Promotes to 龍 (dragon): adds one-square diagonal moves. |
| 角 | Bishop | 1 | Any distance diagonally. Promotes to 馬 (horse): adds one-square orthogonal moves. |
| 金 | Gold general | 2 | One square orthogonally, or one diagonally forward. Does not promote. |
| 銀 | Silver general | 2 | One square diagonally, or one straight forward. Promotes to a gold. |
| 桂 | Knight | 2 | Jumps two forward and one to the side — forward only. Promotes to a gold. |
| 香 | Lance | 2 | Any distance straight forward only. Promotes to a gold. |
| 歩 | Pawn | 9 | One square straight forward; captures the same way. Promotes to と (tokin), a gold. |
The gold general is the key piece
Almost everything promotes to a gold. The gold moves one square in six directions — all except the two diagonals behind it — and it is the standard defensive piece and the standard mating piece. Learn the gold's move first, and five of the eight piece types come free.
Note that shogi pawns capture straight ahead, not diagonally. That single difference makes pawn structure almost irrelevant and the shogi board far more open than a chess board.
Promotion
A piece that moves into, out of, or within the promotion zone may promote at the end of that move. Promotion is optional — you turn the piece over to show its promoted value — except that a piece which could never move again (a pawn or lance on the last rank, a knight on the last two) must promote.
When not to promote
A promoted silver moves like a gold — which means it loses the silver's backward diagonals. In attacking formations where you need to retreat diagonally, keeping the silver unpromoted is frequently correct. This is one of the first real decisions a shogi player learns to think about.
Drops: the rule that makes shogi different
When you capture a piece it goes into your hand. On any later turn, instead of moving a piece on the board, you may drop a piece from your hand onto any empty square, unpromoted and facing your way.
The consequences are enormous:
- Nothing simplifies. Trades do not reduce material — they transfer it.
- Attacks never really end. A defender who captures your attacking piece has just given you ammunition.
- There are almost no draws. Roughly one shogi game in fifty is drawn, compared with a large fraction of top-level chess games.
The three drop restrictions
- Nifu (二歩): you may never have two unpromoted pawns on the same file.
- Dead pieces: you may not drop a piece where it could never move again — a pawn or lance on the last rank, a knight on the last two.
- Uchifuzume (打ち歩詰め): you may not deliver checkmate by dropping a pawn. You may check with a dropped pawn, and you may mate with a pawn that moves — just not with a dropped one.
Checkmate, repetition and impasse
The game is won by checkmate — the king attacked with no legal escape — exactly as in chess. Because pieces can be dropped, mating nets are tighter and much faster: a piece in hand can appear anywhere.
Sennichite (repetition)
If the same position occurs four times with the same player to move, the game is a draw and is normally replayed with colours reversed. The exception: if the repetition is caused by perpetual check, the checking player loses.
Jishogi (impasse)
Occasionally both kings walk into the opponent's promotion zone where they cannot be mated. The game is then decided on material: rook and bishop count 5 points each, everything except the king counts 1. Under the common 27-point rule, a player with 24 or more points can claim, and the game is drawn if both qualify.
Illegal moves
In tournament play an illegal move — most often nifu — loses immediately. It is the single most common way strong amateurs lose won positions.
Reading shogi notation and handicaps
Squares are named by file then rank, from Black's top right: the square 7六 is the
seventh file, sixth rank. Western notation writes P-7f — piece, direction, square — and
the standard first move of the most popular opening is P-7f or P-2f.
Handicaps
Shogi has the most developed handicap system of any chess variant. The stronger player removes pieces from their own side, and the resulting games are genuinely balanced:
| Handicap | Pieces removed from the stronger player |
|---|---|
| Lance (香落ち) | Left lance |
| Bishop (角落ち) | Bishop |
| Rook (飛車落ち) | Rook |
| Two-piece (二枚落ち) | Rook and bishop |
| Four-piece | Rook, bishop and both lances |
| Six-piece | Rook, bishop, both lances and both knights |
Traditional shogi instruction is built on handicaps: a student plays six-piece against a teacher, then works upwards. Each handicap has its own established strategy, so the system teaches technique rather than just making the game closer.
Common questions
What makes shogi different from chess?
Drops. Captured pieces change sides and can be placed back on the board, so material never leaves the game. That makes attacks self-sustaining, endgames extremely sharp, and draws very rare.
Can you drop a piece anywhere?
On any empty square, with three exceptions: never two unpromoted pawns on the same file (nifu), never on a square where the piece could never move again, and never a pawn drop that delivers checkmate (uchifuzume).
Do shogi pawns capture diagonally?
No — shogi pawns move and capture one square straight ahead. This is why shogi has no pawn structure in the chess sense and why the board opens up so quickly.
Is promotion compulsory in shogi?
No, it is optional, except for a piece that would otherwise have no legal move ever again. Choosing not to promote a silver is a common and often correct decision.
How do handicaps work in shogi?
The stronger player removes their own pieces — a lance, a bishop, a rook, or more. Each handicap has its own established strategy, and the system is the backbone of traditional shogi teaching.
Are draws common in shogi?
No. Because material never leaves the board, roughly one game in fifty ends in a draw, compared with a large share of top-level chess games.
