Both these shows are pretty chilled out comedies that follow a group of schoolgirls as they go about their ordinary lives. The comedy is pretty similar in each, the pace is equally relaxed and really, if you're a fan of these schoolgirl comedy shows then i see no reason why these wouldn't appeal to you.
In a moment of pure warmth and happiness, it is said that children of the light, known as Tamayura, will appear. Fuu Sawatari is a young girl who loves taking photographs the same way that her beloved father did while he was alive. Having recently moved to the town her family frequently visited when she was younger, Fuu enjoys her life to the fullest alongside her friends Kaoru, Norie and Maon. Whether the gang have a sleepover, chase a furry cat around town, or simply enjoy a delicious lunch, Fuu always has her camera in hand in the hopes of finally capturing the illusive Tamayura on film.
Both are very slow paced slice of life anime that follow a group of school girls who live in a small, tight-knit community. They're both pretty relaxing, indeed nothing happens at all for large spells in each, but if you found one enjoyable then the other will be worth a watch.
Yui, Yukari and Yuzuko have just entered high school, eager to have a great time. They quickly become the sole members of the Data Processing Club, using the computers frequently to look up information and find interesting videos. Whether they're debating the merits of sauce on curry bread, trying to determine how some women manage to have huge breasts or dealing with the sweltering heat, these three friends will also manage to have fun in the process.
While these shows may not be set in the same location, have similar themes or have the same kind of pacing, i think the fact that both shows follow a group of young schoolgirls as they have many comedic interactions is more than enough to recommend these shows together.
Yuyushiki is a little more fast paced, and a bit more random, but if you enjoyed one of these shows comedy style then the other should hold your attention. Just be aware that Non Non Biyori is considerably slower paced than the former, even if both can be pretty relaxing for the genre. But lets face it, people who enjoy one moe comedy tend to enjoy most others to some degree, so give the other a go if you've seen one of them!
