I like the slice of life bits of K-On! but I don’t like anime about musical bands unfortunately so looking for other slice of life anime to fill that
There’s been a bunch of great suggestions in here.
I would like to add A-Channel https://anilist.co/anime/9776/AChannel
And Seto no Hanayome https://anilist.co/anime/2104/seto-no-hanayome
I’m guessing that you are looking for slice-of-life (SOL) anime that are also cute-girls-doing-cute-things (CGDCT) anime given that you asked specifically for something like K-On! instead of something like Barakamon or Skip and Loafer
Here are more CGDCT SOL anime, but these are a bit more degenerate:
Sakura Trick
Is this the one where the power of yuri defies the laws of physics?
That scene was peak.
- Aria
- pure slice of life, heartwarming
- start with Aria the Animation, NOT Origination despite the name
- Hidamari Sketch
- pure slice of life, art school, comedy
- Nichijou
- comedy, school
- Danshi Koukousei no Nichijou
- comedy, school
- Mushishi
- supernatural, travel
- Lucky Star
- comedy, school
- Minami-ke
- comedy, family
If you especially liked K-On!, then I guess Lucky Star is the closest one, with no music band stuff. Note that LS has tons of references to other media, so if you’re new to anime, 80% of the jokes will fly over your head.
Nichijou is very comedic, and so is the other one with Nichijou in the name (they are unrelated, just the generic term “nichijou” means “daily life”).
The Aria series is my favorite; it’s very slow, to the point of being boring, but you grow to really love the characters and end up bawling your eyes out when it ends.
Nichijou will always hold a special place in my heart. Slice of life anime with a level of joke escalation to rival Key and Peele.
- Aria
I think “Is the order a rabbt” and “Lucky star” are most similar to “K-ON!” but without music bands. If you ok with camping then “Yuru Camp”.
Haven’t seen K-On myself, a couple of slice-of-life anime that pops up in my head.
- A Place Further Than the Universe
- Skip and Loafer
- Miss Kobayashi’s Dragon Maid
If you want something that’s airing right now “mono” fits a bill. It’s about a girls taking pictures with various cameras.
Already watching it
There are a lot of them, don’t know what you will like so I will a few of my favorites
- Horimiya
- Daily lives of Highschool boys (more comedy than SoL)
- Aharen san wa Hakarenai
- Akebi Chan no Sailor Fuku
Azumanga Daioh, still the GOAT.
Azumanga Daioh is top 5 anime of all time for me. No question.
Yuyushiki, maybe? It’s slice-of-life with three girls in a computer club instead of a music club. I liked K-On’s humor more, but I remember thinking they were similar when I watched it a long time ago.
I’ve already watched Yuyushiki and enjoyed it
I don’t know if I’d call it slice of life, but you might like Anne Shirley (currently airing). For non-airing stuff consider Mr. Villain’s day off, Interviews with Monster Girls, Gabriel Dropout and My Dear Friend Nokotan, in that order.

Asobi Asobase

Yuru Yuri
Yuyushiki

Non Non Biyori
Azumanga Daioh
Akebi’s Sailor Uniform
Diary of our Days at the Breakwater
Skip and Loafer, that seems pretty similar to K-ON
Personally, I find that there is a significant difference between them: Skip and Loafer has quite a bit of conflict-based drama; K-On! doesn’t.
