Nichijou, Poputepipikku Recommendations
Both series are sketch comedies playing off subverted expectations. Nichijou pokes fun at the everyday; Pop Team Epic gets its laughs from its absurdity.
How can Nichijou not be on the recommendations for this.
It posses a similar tone with short "stories" around random topics related to the main cast.
Even the top notch quality on animation and originality that Poputepipikku has is similar to that of Nichijou. (Even tough I've noticed that Poputepipikku uses mostly CG on their action shots, or to add more detail to the action made. In Nichijou's case it is mostly traditional animation with use of CG for emphasis on backgrounds and keep a consistent scale of said background while blending it with 2D painted backgrounds in close shots).
Also on both shows the characters have defined
Both are similar in that they are comedic series with outrageous skits and characters. Nichijou feels more refined as it has some semblance of story/recurring characters where Poputepipikku is just 100% short hilarious gags.
