Soap Bubble Ninjutsu

Utakata uses Soap Bubble Ninjutsu from the of Water Release ninjutsu. He uses a special pipe to create his highly versatile bubbles.

In the manga, it was shown that this line of ninjutsu allows Utakata to create bubbles with an explosive composition that he can manipulate to attack the enemy. These bubbles can either burst on their own or upon Utakata's command. In the anime, where this technique is expanded on, it is shown to be extremely versatile: Utakata can float inside his bubbles for transport, as well as use them offensively by trapping his enemies in them and filling the bubbles with water to drown them. These bubbles can also be filled with different materials, such as blinding powder, smoke, acid or sticky slime.

In the anime, it was shown that Utakata's master also carried a bubble blower with him, hinting that he also used this form of ninjutsu.
