Title Interpretation

windmillness said:
The name of the title originates from the words "ao haru" meaning "blue spring," a quasi-synonym for the Japanese word "seishun" which uses the same kanji characters for "ao haru". It can be translated to mean "the springtime of (one's) life" (i.e youth, adolescence). "Raido" or ride, as you already know, derives from that exact English word. Putting the two together, the meaning of the title goes something along the lines of "riding one's springtime of life/youth." Thus, Ao Haru Ride is about the journey of the title's adolescent characters through their most turbulent and developmental years as they face internal struggles, discover themselves, and fall in love. To further convey this message, the fictional station the main characters use everyday to get to school is called Aoharaido (青原井戸) station, a play on the title.
