Is there a Japanese version of kids next door?

There is no official Japanese version of the show "Kids Next Door" (KND). While the show was popular globally, there hasn't been a direct adaptation or remake in Japan.

However, it's worth noting that Japanese animation, or anime, often features themes and ideas similar to KND:

* Superhero Kids: There are many anime series featuring young heroes with unique abilities and missions, such as "Astro Boy", "Digimon", and "Pokémon".

* Secret Clubs/Organizations: Anime like "Cardcaptor Sakura" and "Pretty Cure" feature groups of children with special powers or goals, often working together in secret.

* Fighting for the Rights of Children: Shows like "Future Diary" and "Death Parade" explore themes of child rights and challenging adult authority, though in a darker and more mature way.

So, while no direct Japanese adaptation of KND exists, you might find similar themes and storylines in other Japanese anime.
