Ping Pong the Animation, Shouwa Genroku Rakugo Shinjuu Recommendations
They might seem different at first - the one is about the art of storytelling (rakugo) the other one is about sports (ping pong/table tennis).
But you should easily recognize they are similar if you watch them both. I'd never recommend any other generic sports anime to Ping Pong. Ping Ping is more than just sports. Also ganbatte anime are different from this.
Ping Pong and Shouwa Genroku Rakugo Shinjuu are both character-driven and about two guys that are connected by ping pong (Ping Pong) and rakugo (Shouwa Renroku Rakugo Shinjuu). While they are friends they also are rivals.
You don't need to know anyting about ping pong/rakugo
