|This is the article on the ninjutsu used by Kurotsuchi. For the ninjutsu used by Yahiko, head to Water Release: Wild Water Wave.|
The user launches a large jet of water from their mouth through their cupped hand. This gives the appearance of playing a trumpet, hence the name.
- The Japanese romanisation of this technique's name, Suiton: Mizurappa, and the hand seals used for its activation are the same as Water Release: Wild Water Wave.
