If you liked the K-On! anime, the Anime-Planet community thinks you'd like:
There’s never a dull day in lives of the Hekiyou Academy student council! President Kurimu has a sweet tooth and neglects her duties with ease, while secretary Chizuru skillfully manipulates those around her. Otaku Mafuyu obsesses over writing online walkthroughs, and is constantly hounded by Ken, the only male of their crew and an eroge addict who has the ultimate goal to turn the entire council into his harem. Luckily for Mafuyu she’s protected from his advances by Minatsu, her sporty and tomboyish sister! Together, the five repeatedly struggle in their fight against boredom, making constant otaku references and fighting against the journalism club along the way!
Both shows revolve around daily life in a high school club. The shows don't have any particular stories. Just chatter among the club members and the events almost always take place inside the club room.
Asuna Harukaze is a girl who loves tennis to the point where she practices her swings with a pitchfork while working on the family farm. At school she is a member of the Soft Tennis Club along with the enthusiastic Kotone, food-crazy Chitose and bizarre yet talented Kurusu. With a big tournament approaching, the girls are taking practice more seriously than ever, but with Asuna’s strange and perverted logic surfacing at every turn and Chitose’s inability to win a single match, can the club emerge triumphant and make it to the nationals?
Both series are slice-of life comedies, having a similar group of girls as the main cast. Both focus on club activities (K-On! has music, Softenni has soft-tennis). Both are moe-heavy. Softenni has more fanservice, though.
Check out one if you like the other.
Super Sonico is an 18-year old college student who plays guitar for the three-girl band Fastest Speed in Space and models for pin-ups. In spite of her busy schedule, she still finds time to help her grandmother at her restaurant. One night, her band members Suzu and Fuuri, are late to a concert, forcing her to play alone. The result of that show will have far-reaching consequences for Sonico.
Both anime feature a lot of young women playing instruments and a whole lot of focus on slice of life stuff (keep in mind that SoniAni is far more vapid than K-On! ever manages to be). SoniAni is very much ecchi, while K-On! usually manages to not sink to such low tactics. The cast in K-On! is much more varied and features several mains, while SoniAni is basically just about Sonico. Still, if you saw one and want more female characters playing instruments now and then, do check the other one out.
The brash Hotori Arashiyama is a far from regular girl with the lofty dream of becoming a genius high school detective, but for now she is working at the Seaside maid café to earn some extra money. Unfortunately the establishment itself is deserted and the teen is far from being the epitome of a gracious maid. Enter Toshiko, Hotori’s friend and classmate, whose expertise and passion for maid cafés – as well has her interest in Sanada, one of the few regular customers – leads her take on the quest to turn Seaside into a bistro to be proud of. However, can a cafe owned by an elderly woman whose solution to everything is curry and staffed by a clueless, foolhardy teenager really become a success, or even attract more than the usual four patrons?
The humor and randomness in both animes are so similar, so if you like K-on you would probably enjoy Soredemo Machi wa Mawatteiru too, and vice-versa. The ending song of Soredemo Machi wa Mawatteiru also reminds me of K-on because the characters are playing as if they were a band.
A photograph is a mysterious force that creates magical moments the instant the shutter closes and allows people’s hearts to connect. For the new girl in town, Fuu Sawatari, this is more than a saying but a way of life as she spends her days quietly attempting to capture those special instances on film and use them to bring others joy. Along with her friends – and her beloved camera – Fuu reminisces about her father, begins to contemplate where her future lies and wonders whether she can capture more of the mysterious Tamayura light bubbles in her photos filled with warmth and friendship.
K-On and Tamayura first felt similar to me with their cast - quirky young high school girls building their friendships over food, tea, and random outings. They also both have that moe feeling, which is laid on much thicker in K-On. Where K-On deals with making music Tamayura focuses on photography. Two great slice-of-life titles which will leave you warm inside!
