Japanese Chess (Shogi) Explained: Piece Moves, Drops, Promotion and How to Play

Quick answer: Japanese chess is called shogi (将棋). It is a two-player strategy game on a 9×9 board. Each player starts with 20 pieces, and the goal is to checkmate the opposing king. Its defining rule is that a captured piece can return to the board as part of the capturing player’s army. That single difference makes shogi feel very different from Western chess.

This beginner’s guide explains the actual setup, every kind of piece, the three restrictions on drops, promotion, and a practical way to complete your first game. The movement rules below follow the Japan Shogi Association and the GNU Shogi rules reference.

Shogi at a glance

How do you set up a Japanese chess board?

Place the 9×9 board so both players face each other. Every piece points toward the opponent. Unlike a Western chess set, you cannot rely on black and white piece colors to identify ownership. Reading the direction of the pieces is part of learning the game.

1. Back rank: arrange lance, knight, silver general, gold general, king, gold general, silver general, knight, lance, reading from one edge to the other.
2. Second rank: place your bishop and rook on the two squares one file in from opposite edges, as shown in a standard setup reference; the other seven squares are empty.
3. Third rank: place all nine pawns across the row.
4. Repeat, mirrored: your opponent uses the same 20 pieces, pointing back toward you. The middle three ranks begin empty.

The back-rank pattern is symmetrical, but the rook and bishop occupy opposite sides in the two players’ positions. If you are using a set for the first time, compare your layout with the labeled starting board in the GNU manual rather than guessing from the kanji.

How each shogi piece moves

Every piece captures by landing on a square occupied by an opponent’s piece. The rook and bishop cannot jump over other pieces; the knight can. “Forward” always means toward your opponent’s side, regardless of the piece’s printed characters.

The pawn difference is especially important for chess players: a shogi pawn captures in front of itself, not diagonally. There is no opening two-square pawn move and no en passant. Gold generals and kings never promote. For a piece-by-piece visual reference, see the Japan Shogi Association’s movement guide.

The rule that makes shogi different: captured-piece drops

Suppose you capture a silver general. Instead of removing it from the game permanently, you keep it in view beside the board, usually called your hand. On a later turn you can use your entire turn to place that silver on a legal empty square, facing the opponent. You do not also move another piece that turn.

Three rules for legal drops

1. No immobile drops: you cannot drop a pawn or lance onto its final rank, or a knight onto either of its last two ranks, because that piece could never move.
2. No two unpromoted pawns on one file: called nifu. You may not drop a pawn into a column containing one of your own ordinary pawns. A promoted pawn (tokin) does not count toward that limit.
3. No immediate pawn-drop checkmate: called uchifuzume. You may drop a pawn to give check if the opponent can escape, but may not mate directly with the dropped pawn.

A dropped piece arrives unpromoted, even in the promotion zone. If you capture a promoted rook, you receive a regular rook in hand. This is why trading pieces in shogi does not simplify a game the way trading pieces often does in Western chess: the pieces can come straight back into play.

How promotion works

Each player’s promotion zone is the farthest three ranks. If a piece moves into, out of, or within that zone, an eligible piece may be turned over to its promoted side at the end of the move. For a pawn, lance, knight or silver, the promoted piece moves as a gold general. A promoted rook gains short diagonal moves, and a promoted bishop gains short straight moves.

Promotion is generally optional. It becomes mandatory when leaving a piece unpromoted would leave it unable to make a move: a pawn or lance on the last rank, or a knight on either of the last two ranks. You cannot promote a piece merely by dropping it on the far side. Promotion happens on a qualifying movement, not on the drop itself.

Check, checkmate and resigning

Check means your king is threatened with capture on the next move. You must get the king out of danger, capture the attacker or block the attack where possible; you cannot make a move that leaves your own king in check. Checkmate means there is no legal answer to the threat, and the game ends. In practice players commonly resign when defeat is clear.

Shogi has repetition and entering-king procedures that are unlike Western chess’s fifty-move rule or stalemate draw. Tournament regulations can contain detailed adjudication requirements, so beginners should use the rules of their particular platform or event for unusual endings. For a basic explanation of check and mate, consult the Japan Shogi Association.

Japanese chess versus Western chess

If you already know chess, our guides to castling in Western chess and en passant show two familiar concepts that do not apply to shogi. You can also compare the ways the two games record moves in our chess notation guide.

A practical five-step plan for your first game

1. Identify the pieces: learn the king, gold, silver, rook, bishop and pawn first. Add knight and lance once you can recognize their kanji.
2. Protect your king: before launching a rook attack, move your king away from the center and build a defensive grouping with golds and silvers. In shogi, a defensive structure is often called a castle, but it takes several regular moves rather than one special move.
3. Open a line deliberately: move a pawn to free the bishop’s diagonal or the rook’s file. Do not give away a pawn without checking how the opponent might drop it later.
4. Look at both boards and hands: after every capture ask, “Where can my opponent drop this piece?” This prevents surprise attacks.
5. Practice one rule at a time: in one game focus on legal pawn drops; in the next, concentrate on using the promotion zone. Gradual practice makes the unusual rules stick.

Where can you learn shogi online?

The International Shogi Forum’s beginner videos, produced for the Japan Shogi Association’s international audience, cover rules in English. The GNU Shogi project provides a playable free-software engine and a detailed rules manual. Learning the authentic rules first is more valuable than searching for random unofficial “shogi cheats” or downloading unverified software.

Frequently asked questions

Is Japanese chess the same game as shogi?

Yes. “Japanese chess” is an English description of standard shogi, though there are also historical variants with different board sizes and rules.

How many pieces does Japanese chess use?

There are 40 starting pieces: 20 per player. Each side has one king, one rook, one bishop, two golds, two silvers, two knights, two lances and nine pawns.

Can you reuse a piece you captured?

Yes. Captured pieces move into your hand and may be dropped onto legal empty squares on later turns. They belong to the new player and are always dropped unpromoted.

Can a shogi pawn move diagonally?

Not as an ordinary pawn. It moves and captures one square straight forward. Once promoted to a tokin, it uses gold-general movement, including diagonally forward.

Can you drop a pawn for instant checkmate?

No. Japanese chess specifically prohibits checkmate caused directly by a pawn drop. A pawn already on the board can move to deliver mate.

Which player goes first in shogi?

The player called sente, typically designated Black in English-language diagrams, makes the first move. Both players’ physical pieces usually have the same wooden color.

Bottom line: Japanese chess rewards patient king safety and careful management of captured pieces. Learn the drop rule early: it is the reason a harmless-looking exchange can create a dangerous threat several moves later.
