The manga series contains examples of the following tropes:
- Accidental Misnaming: Hietta Happosai, big time.Rantaro: Chingensai Sameta!!Kirimaru: Samela Zensai!!Shinbe: Hietta Namayasai!!Happosai: *hitting the three nintamas* It's Hietta Happosai, idiots!

- Big Eater: Shinbe
- Brand Names Are Better: Invoked by Kirimaru.Kirimaru: I start selling Infra-red UnderpantsYamada-sensei: How is this different from normal underpants?Kirimaru: It's not. But more people would buy it if it uses the name "Infra-red"
- Brick Joke: At the start of the volume 23, Shinbe is supposed to remember a number that indicates a measurement of a warship. He can't. Hundred of pages later, he gives the wrong number and the ship built turns funny.

- Fatal Flaw: Fuwa Raizou is told to be thinking too much.
- Hurricane of Puns: half of the jokes in the series are these, alternating between this and Incredibly Lame Pun

- Shown His Work: Unlike most ninja comics, the ninjas are actually doing things close to what real ninjas did.
- Status Quo Is God: Taken Up to Eleven with the nintamas going through many Summer and Winter breaks but never graduate or even promote.
