One of the most exciting moments in any shogi game is promotion — when a piece crosses into the opponent’s territory and transforms into a stronger version of itself. Understanding exactly which pieces can promote, how promotion works, and when to promote (or not to promote) is essential knowledge for every shogi player.
This guide covers everything you need to know about shogi piece promotion, from the basic rules to the strategic decisions that separate beginners from experienced players.

1. How Promotion Works
When a piece moves into, within, or out of the opponent’s promotion zone, the moving player may choose to promote that piece. Promotion is indicated by flipping the piece over to reveal its promoted face — in physical shogi sets, the promoted side is printed in red.
The decision to promote is made immediately after the move. You must declare whether to promote before your opponent makes their next move. Once you decide not to promote, you cannot change your mind on a later turn — the piece must move into the promotion zone again before you get another chance.
Promotion is voluntary in most cases. There are exceptions (see Forced Promotion below), but generally you choose whether or not to promote each time the opportunity arises.
2. The Promotion Zone
The promotion zone consists of the opponent’s three back rows (rows 1, 2, and 3 for Sente; rows 7, 8, and 9 for Gote). Any eligible piece that:
- Moves into the promotion zone from outside it
- Moves within the promotion zone (from one promotion-zone square to another)
- Moves out of the promotion zone (from inside back to outside)
…may be promoted at the end of that move.
This is broader than chess promotion, which requires reaching the last rank. In shogi, even moving from row 4 to row 3 (entering the promotion zone) triggers the promotion option.
3. Which Pieces Can Promote?
Six of the eight piece types can promote. Two cannot:
- King (王/玉) — cannot promote (already the most powerful piece)
- Gold General (金) — cannot promote (already at its maximum form)
The six pieces that can promote are:
- Rook (飛車) → Dragon King (竜王)
- Bishop (角行) → Dragon Horse (竜馬)
- Silver General (銀将) → Promoted Silver (成銀)
- Knight (桂馬) → Promoted Knight (成桂)
- Lance (香車) → Promoted Lance (成香)
- Pawn (歩兵) → Tokin (と金)
4. Promoted Piece Movements
Each promoted piece moves differently from its base form. Here is what each piece becomes after promotion:
Rook → Dragon King (竜王 / Ryūō)
The Rook already moves any number of squares horizontally or vertically. After promotion, the Dragon King gains the additional ability to move one square diagonally in any direction. This makes it the single most powerful piece in shogi — it combines the long-range power of the Rook with the King’s diagonal movement.
Bishop → Dragon Horse (竜馬 / Ryūma)
The Bishop moves any number of squares diagonally. After promotion, the Dragon Horse gains the ability to move one square horizontally or vertically. Combined with its existing diagonal range, the Dragon Horse can reach any square on the board given enough moves — making it arguably the second most powerful piece.
Silver General → Promoted Silver (成銀)
The Silver General moves one square diagonally or one square forward. After promotion, it moves like a Gold General — one square in any direction except diagonally backward. The Promoted Silver is stronger than the base Silver in most positions.
Knight → Promoted Knight (成桂)
The Knight can only jump forward in a narrow L-shape. After promotion, it moves like a Gold General — highly versatile in all directions. The Promoted Knight is dramatically more useful than the base Knight, especially in the endgame.
Lance → Promoted Lance (成香)
The Lance can only move forward any number of squares. After promotion, it moves like a Gold General. The Promoted Lance gains backward movement for the first time, making it much more flexible.
Pawn → Tokin (と金)
The Pawn can only move one square forward. After promotion, it becomes a Tokin (と), which moves like a Gold General. The Tokin is one of the most feared endgame pieces because pawns are numerous, cheap to capture, and devastating once promoted. A Tokin near the opponent’s King creates enormous attacking pressure.
5. When to Promote (and When Not To)
Promotion is almost always the right choice, but there are specific situations where it is better to wait.
Almost Always Promote:
- Rook — promote whenever possible. The Dragon King is enormously stronger.
- Bishop — promote whenever possible. The Dragon Horse is dramatically more useful.
- Pawn — promote whenever possible. A Tokin is worth many times more than a Pawn.
- Knight and Lance — promote to enable backward movement and more flexible use.
Sometimes Do NOT Promote (Silver):
The Silver General is the most interesting promotion decision. The Silver can move diagonally, including backward diagonally — something the Gold General (and therefore the Promoted Silver) cannot do. In certain attacking positions, the Silver’s unique diagonal retreat allows for specific tactical maneuvers that the Promoted Silver cannot perform.
The rule of thumb: if you need the Silver for attacking (especially for piece sacrifices and diagonal maneuvers), keep it unpromoted. If you need it for endgame purposes, promote it.
Strategic Promotion Timing:
- Promote immediately when the promoted form is clearly more useful right now
- Delay promotion if the piece is in a position where its base movement is specifically needed for the next few moves
- Consider promoting mid-attack — some attacking sequences use an unpromoted piece to initiate an exchange, then promote the piece that results from the trade
6. Forced Promotion
In certain situations, promotion is mandatory because leaving the piece unpromoted would trap it permanently — it would have no legal move on any future turn:
- A Pawn or Lance on the opponent’s last rank (row 1 for Sente) must promote — a Pawn or Lance on the last rank can never move again if unpromoted
- A Knight on either of the opponent’s two back ranks (rows 1 or 2 for Sente) must promote — it has no legal forward L-shape jump available from those ranks
In all other situations, promotion is a choice. But when forced promotion applies, the piece must be promoted on that move — you cannot place a Pawn on the last rank and leave it unpromoted.
7. Drops and Promotion
Captured pieces — those in your piece reserve — always enter the board in their base (unpromoted) form, even if they were captured while promoted. A Dragon King you capture enters your hand as a Rook. You can drop it on any empty square, but it will not be promoted until it moves into the promotion zone again.
This is a critical strategic implication: capturing a promoted Rook or Bishop is enormously beneficial, because it adds a powerful base piece to your hand that can become powerful again — but your opponent loses a promoted piece immediately. This is why Rook and Bishop exchanges often trigger major strategic shifts in the game.
8. Frequently Asked Questions
Can I choose not to promote and promote on a later turn?
Yes, as long as the piece makes another move into, within, or out of the promotion zone. Choosing not to promote does not lock you out permanently — it just means you need to move through the zone again to get another opportunity.
If my promoted piece is captured, does my opponent get a promoted piece?
No. All captured pieces revert to their base form and enter the captor’s piece reserve unpromoted. A Dragon King becomes a Rook when captured. A Tokin becomes a Pawn.
Can I promote a piece that was just dropped?
No. Dropped pieces cannot be promoted on the turn they are dropped, even if they are dropped into the promotion zone. They must make a separate move from within the promotion zone to earn promotion.
Is it bad strategy to avoid promoting your pieces?
Generally yes — promoted pieces are almost always stronger than unpromoted ones. The only exception is the Silver General in specific attacking situations. As a beginner, default to promoting whenever you can.
Summary
Piece promotion is one of shogi’s most exciting mechanics and one of its most strategically rich. The key principles:
- Promotion is available any time a piece moves into, within, or out of the opponent’s three back rows
- Six pieces can promote; King and Gold cannot
- Promoted Rook (Dragon King) and promoted Bishop (Dragon Horse) are the two most powerful pieces in the game
- All other pieces promote to Gold General movement
- Promotion is almost always the right choice — the Silver is the main exception
- Captured promoted pieces always revert to their base form
- Dropped pieces cannot be promoted on the turn they are dropped
