Ninjutsu Yashiki(Ninja mansions(house))

Ninja mansions were places where ninjas lived and trained, and they were built with special structures designed to protect against external enemies. Particularly in Iga and Koga, ninja mansions contained hidden passages, traps, and escape routes that were designed to prevent enemy infiltration. These mechanisms were crucial for ninjas in their roles of intelligence gathering and combat.
1. Hidden Doors and Secret Rooms
Ninja mansions had numerous hidden doors and rooms cleverly concealed in walls and floors. These were used to move around the mansion unnoticed or to hide from enemies. Below are some of the key mechanisms:
Revolving Doors: What appears to be part of the wall is actually a revolving door. When pushed, the wall rotates, leading to another room or hidden passage. This was used for quick escapes when being pursued by enemies.
Trap Doors: Traps placed in the floor or ceiling, which would open when a specific section was stepped on, leading enemies to fall into a pit. Ninjas used these to capture enemies or buy time for escape.
Push-Hidden Doors: A seemingly normal wall, which opens when lightly pushed, revealing a hidden door that allows quick movement between rooms or passageways within the mansion.
2. Hidden Passages and Escape Routes
Ninja mansions also contained hidden passages and escape routes that could be used to flee from enemies in emergencies. These passageways connected different parts of the mansion or led outside to safety, allowing ninjas to escape undetected.
Underground Passages: Tunnels dug beneath the mansion that led outside or to a secure area. These were particularly useful when the mansion was surrounded by enemies.
Attic Passages: Narrow passages in the attic, allowing ninjas to move quickly within the mansion without being seen. These hidden routes were vital for avoiding detection by enemies.
3. Defensive Traps
Ninja mansions had numerous traps designed to strengthen defenses and confuse or harm intruders. These traps were used to create chaos for enemies entering the mansion or to physically attack them.
Stone Drop: Traps installed in the ceiling or high places, where stones or heavy objects would be dropped onto enemies who entered the mansion.
Spike Floors (Shishidoko): Traps set into the floor where sharp spikes or blades would spring out when stepped on, injuring enemies. These traps were cleverly disguised so they appeared to be part of the normal floor.
Maze-like Room Layout: The rooms in ninja mansions were arranged like a maze, making it difficult for intruders to easily reach their destination. This would confuse enemies and buy time for the ninjas.
4. Disguised Mansion Structures
From the outside, ninja mansions were often designed to look like ordinary farmhouses or homes to avoid drawing attention from enemies. Although they appeared simple and ordinary, the interiors were filled with hidden doors, passageways, and traps, incorporating many tactical elements.
Disguised Exterior: The entire mansion was made to look like a typical farmhouse or residential home, making it less likely to attract attention from external enemies. This helped ninjas carry out intelligence activities or remain hidden.
Double Ceilings and Walls: The ceilings and walls of the mansion were double-layered, with hidden passages and rooms inside. Even if the mansion was attacked, these provided safe hiding places for the ninjas.
5. Psychological Mechanisms
Ninja mansions also contained tricks designed to create psychological pressure on intruders. Dark or narrow spaces were used to instill fear, and special methods were employed to allow ninjas to move silently without being detected.
Sound Traps: Certain areas of the mansion were designed to creak or make noise when stepped on, allowing ninjas to detect intruders' footsteps. Ninjas also trained in special walking techniques that allowed them to move without making noise.
♪Ninja’s Hideaway♪
[Chorus]
Shadows hidden deep, the traps begin to move
Donden gaeshi tricks, confusing all the fools
The pitfall waits ahead, where unseen paths lay still
Ninja’s hideaway, this fortress stands to kill
[Verse 1]
Turn the wall around, the secret path appears
With stealthy steps, we vanish in the night’s dark fears
Beneath the tatami lies a hidden door
Even the pursuers can’t chase us anymore
[Chorus]
Shadows hidden deep, the traps begin to move
Donden gaeshi tricks, confusing all the fools
The pitfall waits ahead, where unseen paths lay still
Ninja’s hideaway, this fortress stands to kill
