* AnimeFirst: A manga adaptation began serialization in May 2012.
* PortmanteauSeriesNickname: [=AnoHana=]. It's sorely needed given the full title's length.
* RealSongThemeTune: The ending theme is a cover of Zone's "secret base ~Kimi ga Kureta Mono~ [[note]]What You Gave Me[[/note]] (10 years after ver.)" by the three leading ladies.
* TheRedStapler: The town of Chichibu has seen an immense increase in visitors because of its appearance in the anime, which is milked for all it's worth by the local tourism industry.
* StarMakingRole: Meiko/Menma was this for Creator/AiKayano.
* WhatCouldHaveBeen: The anime was originally going to have slapstick comedy with erotic tones, as the characters were exploring their budding sexuality in their adolescence, with the focus being on their childhood and how they were maturing as they were growing up.
