Master the Shogi Anaguma! Solid King Defense Basics and Play
Published
When just learning Shogi, it is easy to focus only on attacking the opponent's camp. But if your king remains defenseless, a slight counterattack puts you in trouble. That is why building a protective setup called a castle is so vital.
Among many castles, the one known for high king safety and clarity for beginners is the Shogi Anaguma. Tucking the king deep into the corner like a hibernating bear brings great security. Let us examine the role of castles and the core aims of Anaguma step by step.
Castle Basics and the Defining Feature of Anaguma
Shogi is won by checkmating the opponent's king first. Because captured pieces can be reused as pieces in hand, leaving the king in the center leaves it exposed to major pieces like the rook or bishop, with nowhere to run. Moving the king toward the edge before fighting starts and fortifying it with gold and silver generals is called forming a castle.
The main feature of Anaguma is moving the king to the very corner square. Placing it there limits the directions from which an opponent can attack. Tightly placing gold and silver generals in front creates a solid camp that withstands small assaults.
| Castle Name | Typical Move Count | Defensive Solidity | Suitable Play Style |
|---|---|---|---|
| Anaguma | High | Extremely solid | When attacking steadily |
| Mino Castle | Low | Well balanced | When attacking quickly |
| Crab Castle | Low | Strong against attacks from above | Dealing with early quick attacks |
Basic Structure of Anaguma and Setup Steps

This diagram shows Sente's king entering square 9i, with the lance in front at 9h. The first goal in Anaguma is tucking the king into 9i like this. In standard joseki, advancing the lance to 9h to open space and moving the king there is a standard sequence.
Once the king reaches 9i, the next step is bringing up defensive anchors: the gold and silver generals. The basic steps are as follows:
- Advance the lance forward (9h) to clear space for the king
- Move the king into that open square (9i) to tuck it into the corner.
- Pull the silver general adjacent to the king (8h) to build a wall.
- Place the gold generals around the silver general (such as 7h and 6h) to link them together.
Densely grouping pieces this way eliminates gaps for enemy pieces to enter. While it may feel complex at first, the basic flow of tucking the king to the edge and fortifying its perimeter is always the same.

As shown, when the king sits on 9i, a silver general on 8h, and gold generals on 7h and 6h, Anaguma nears completion. The gold general on 7h supports the silver general on 8h, and overlapping influence prevents the defense from easily breaking even if the opponent drops a piece.
A big reason beginners choose Anaguma is that it is hard to receive a check. A check is a move directly targeting the king. Near the center, the king easily faces checks from distant rooks or bishops, forcing responses and halting your attack. In Anaguma, no check can reach the king unless the wall of gold and silver generals is breached.
The appeal of this castle is being able to concentrate calmly on your attack without worrying about counterattacks. Peace of mind from a solid defense also helps you view the whole board with composure.
Weaknesses of Anaguma and Tips for Real Games
Although Anaguma boasts ironclad defense, it is not flawless, and several weaknesses require caution. Understanding both pros and cons is key to winning more games.
- Takes many moves to complete: Moving the king to the corner and lining up gold and silver generals takes moves. A rapid attack before completion risks breaking it.
- Narrow escape routes for the king: Tucked in the corner behind gold and silver generals, once the wall is breached and check is given, there is nowhere to run, leading quickly to checkmate.
- Overcommitting pieces to defense: Committing most gold and silver generals to defense leaves fewer pieces for attacking, often reducing offensive power.
To overcome these weaknesses, build it when the opponent is slowly arranging their camp. To practice Anaguma in real games, trying the setup in a mobile app like Shogi: The Grand Court is also recommended. Learning the sequence makes Shogi far deeper and more fun.
Frequently asked questions
What is the origin of the name Anaguma?
It comes from resembling a bear in a hole for winter hibernation. Tucking the king deep into the corner and sealing it with gold and silver generals fits that image.
Can beginners use Anaguma in practical play?
Beginners can use it easily. Although it takes moves, once completed it rarely receives checks, letting you focus on your attack without fearing counterattacks.
What is the most important thing to watch out for when playing Anaguma?
Watch out for quick attacks before the castle is complete. Because building it takes many moves, advance carefully while watching opponent piece moves.
