Yagura Castle: How to Build Shogi's Classic Fortress
The Yagura is the classical castle of Static Rook shogi. The king sits on 8h behind a wall of three generals, a gold on 7h, a silver on 7g, and a gold on 6g, making it the standard fortress when both players keep their rooks home and attack from the front.
What the Yagura Castle is
Yagura means turret, and the castle earns the name. Three generals stack into a wall on the king’s side of the board: the silver stands at the front on 7g, one gold backs it up on 6g, and the other gold sits at the king’s shoulder on 7h. Every square the enemy could use to approach the king is covered at least once, and the important ones twice.
That interlocking cover is the Yagura’s signature. The gold on 7h guards the king’s head; the silver and gold in front guard each other and the pawns above them. An attacker cannot simply trade one defender off and walk in, because each defender is caught by another. Frontal attacks, the kind a fellow Static Rook player sends up the files, grind against this wall and stall.
The cost is time. The full structure shown here takes a dozen of your own moves, and while you build it your opponent builds theirs. Yagura games have a distinct rhythm: two players raising their walls in parallel, watching for the moment the other one pauses construction to grab something.
Watch it get built
The replay below shows a realistic build from the starting position, both sides moving. Watch the order: the pawn on 7g opens the bishop diagonal first, the generals walk up before the king commits, and the king takes the long diagonal walk to 8h only once the wall is standing. Step through it a few times until the order feels inevitable.
Strengths and weaknesses
Strengths
- Three generals form a wall in front of the king, making it very strong against frontal attacks.
- The gold-silver chain on 7h, 7g, and 6g protects every approach square along the king file.
- The king sits far from the main battlefield when both players fight on the rook files.
Weaknesses
- Slow to build: the full castle takes around a dozen of your own moves.
- The edge (9f-9g) and the head of the king can be pried open by pawn sacrifices.
- Vulnerable to side attacks along the eighth rank once the defending golds are pulled away.
When to choose it
Build the Yagura when both players have kept their rooks on their starting files, which means the attacks will come frontally, straight into the castle’s strongest face. That is the classic Double Static Rook setting, and the Yagura has been its main answer for centuries.
Skip it when the enemy rook has swung to face your king’s wing. Against a Ranging Rook opponent the attack arrives from the side the Yagura leaves thin, and Static Rook players reach instead for the Anaguma or a lighter shell. The wall is wonderful, but only when it faces the incoming fire.
Best against: Other Static Rook openings, where both kings castle on the same side and the fight happens on the far files.
Pairs with: Static Rook. See the openings guide for how the opening and the castle fit together.
The other castles
Mino Castle
Static Rook attacks from the front; the castle faces sideways, so frontal pressure hits its strongest wall.
Anaguma Castle
Ranging Rook setups; the Static Rook player burrows in on the far side from the enemy rook and wins the attacking race.

FAQ
What is the Yagura castle in shogi?
The Yagura (meaning turret) is the classical shogi castle for Static Rook games. The king castles to 8h behind a wall of three generals: a silver on 7g, a gold on 6g, and a gold on 7h. It is strongest against attacks arriving from the front.
How many moves does the Yagura take to build?
About twelve of your own moves for the full structure, which makes it one of the slower standard castles. The build order matters: pawns open lines first, the generals climb into the wall, and the king walks across last, once the shelter is ready.
When should I not use the Yagura?
Against Ranging Rook opponents. Their rook points at the wing where the Yagura king lives, so the attack arrives from the side rather than the front, bypassing the wall. In that matchup Static Rook players prefer the Anaguma or a lighter, faster castle.
How do you attack a Yagura castle?
The standard levers are the edge, pried open with pawn sacrifices on the ninth file, and the head of the king, attacked from above once the front is locked. Side attacks along the eighth rank also work once the defending golds have been dragged away from the king.
