Many of the Ghibli movies should be perfectly fine (My Neighbor Totoro, Whisper of the Heart, Kiki’s Delivery Service, Ponyo, The Secret World of Arrietty, …).

Does she have any specific interests? I guess if nothing in general, she might enjoy something like Spirited Away or Spy x Family?

Maybe something chill and comfy like Yuru Camp ?

K-On!, Laid back camp, Sailor Moon, ghibli movies as many have already stated, all good to try

Majo no Tabitabi. A very enjoyable magical adventure. Episode 8 has a jump scare that she might not like, so skip that one or watch it yourself first and decide. The episode itself starts with a warning about this so you don’t need to remember which one it is.

Somali – another magical adventure, I don’t recall it containing any scenes that a child would be uncomfortable with.

Non Non Biyori, Mitsuboshi Colors, and K-on are pretty light-hearted, slice of life, comedies that would all be good

Another vote for Bocchi the Rock, it’s an awesome and inpsiring anime. Plus, I think it could be empowering to a little girl to see an all girl cast kick ass at being rockstars.

The only con I can think of are a few adult gags, though they aren’t super offensive. Most kids shows I watched growing up had adult humor that flew over my head, so it should be fine. Just something to consider.

BoFuri is cute and sfw, no real violence.

Kuma Kuma Bear falls in the same area.

It has some fight but maybe she’ll like CardCaptor Sakura

Spy x Family
