Non Non Biyori

There is absolutely zero sexualization of any character in the series whatsoever. It is all about growing up in an extremely rural area and children learning to find the fun they can have without most modern conviences and the passing of the seasons as the characters grow and mature into young adults. There is one male that is visible in the series, the older brother of two of the main characters, and he is seen as some kind of oddity because of how proficient he is in everything he does.

I absolutely love Non Non Biyori. The manga is filled with these insanely beautiful and extremely highly detailed landscapes of the rural Japanese countryside. The most emotionally taxing part of the story is when the youngest girl makes friends with another girl her age who spends the summer living with her grandparents deep in the country and has to leave when the school year rolls around again. It is very slow, very peaceful, and very heartwarming.
