Suiton No Jutsu

Water Escapes

Ninja relied on extraordinary skills to infiltrate, observe, and evade detection during their daring missions. Among these methods, Suiton No Jutsu allowed them to use bodies of water to their advantage. Whether for hiding from enemies, gathering intelligence, or making a stealthy getaway, this tactic involved submerging themselves in water while remaining able to breathe. 

The Essence of Suiton No Jutsu

One of the key tools for this was the mizutsutsu, a bamboo tube between 30-60 cm in length, used for breathing while underwater. In a revealing video, Jinichi Kawakami explains the practicality of this technique, addressing common misconceptions. While it may seem logical to stay deeper underwater to avoid detection, the mizutsutsu was used close to the water's surface. Why? Longer, slender tubes were impractical for breathing, especially when factoring in water pressure, which would make inhaling air increasingly difficult at greater depths.

Modified Tools and Clever Tricks

While the mizutsutsu was one of the ninja's primary tools, versatility was the key to their success. Kawakami notes that a modified sword scabbard could sometimes be used in place of the bamboo tube. In his demonstration, Kawakami shows how resourcefulness played a major role in ninja survival tactics. Whatever was on hand—be it a bamboo shoot or sword scabbard—could be adapted to fit the needs of the mission.

To remain submerged without floating to the surface, another clever tactic was employed. Ninja would place a rock on their stomach, which acted as a natural weight, holding them down in the water. This simple yet effective method allowed them to stay hidden for extended periods without revealing their presence.

The Role of Camouflage in Water

Another element of Suiton No Jutsu was the use of aquatic plants for camouflage. Some stories suggest that ninja would place water vegetation around themselves while submerged to blend into their surroundings. Kawakami admits that it's unclear whether this technique was an actual historical practice or simply part of the myths that have grown around ninjutsu over the centuries. Nonetheless, it emphasizes the importance of stealth and the lengths ninja would go to remain undetected.

Kawakami's demonstration of Suiton No Jutsu on the Nindo YouTube channel strips away the Hollywood exaggerations and brings viewers closer to understanding authentic ninjutsu.
