Season 1 of Non Non Biyori premiered on 7 oktober 2013.

Asahigaoka might look like typical, boring countryside to most; however, no day in this village can ever be considered colorless thanks to five students of varying ages occupying the only class in the only school in town. The youngest student is first grader Renge Miyauchi, who brings an unadulterated wit, curiosity, and her characteristic catchphrase, "Nyanpasu!" Then there are the Koshigaya siblings consisting of the quiet ninth grader and elder brother Suguru, diminutive eighth grader Komari, and the mischievous seventh grader Natsumi. The recent arrival of Tokyo-raised fifth grader Hotaru Ichijou, who appears overdeveloped for her age and thus naturally holds an air of maturity, rounds out this lively and vibrant group of five classmates.

Season 2 of Non Non Biyori premiered on 6 july 2015.

Far from the hustle and bustle of urban life, and with only a single candy store and bus route to its name, the rural Asahigaoka is certainly not a place for everyone. Nevertheless, the village's children still manage to cheerfully spend their days exploring and having fun in the wilderness around them. One such child, Renge Miyauchi, the youngest of the group, looks forward to the entrance ceremony of the upcoming school year, signalling her entry into first grade and the beginning of her elementary school life. Attending the only school in town, Renge and her friends, seventh grader Natsumi Koshigaya and her eighth grade sister Komari, make the most out of their rural lifestyle, playing and studying everyday.
