On August 10 2002, the eruption of Mount Fuji, as well as a series of large-scale earthquakes tsunamis inflict tremendous damage to Japan, sending the country into a state of emergency. Furthermore, another massive earthquake hit Japan on August 15, splitting the country into two. While Japanese refugees were taken in by various countries, the Japanese government accepted aid from China and the United States, which eventually caused China to govern the North, and the USA to govern the South. 15 years later, the Japanese refugees residing in Taiwan and the Taiwanese citizens find themselves clashing with one another, due to job competition and the unimproving conditions of the Japanese refugees. Genichiro Ryu is a survivor of the catastrophic events that took place in Japan, but was raised in Taiwan by a couple who adopted him. He gets himself involved in the situation between the Taiwanese and the Japanese, hoping that the two parties will be able to coexist with one another.

High school student Aoi Aioi lives with her elder sister, Akane, after a tragic accident took their parents away 13 years ago. Because Akane has since been taking care of her single-handedly, Aoi wants to move to Tokyo after her graduation to relieve her sister's burden and pursue a musical career, inspired by Akane's ex-boyfriend Shinnosuke "Shinno" Kanamuro. Shinno was part of a band until he left for Tokyo to become a professional guitarist after the sisters' parents passed away, and he was never to be seen again.

One afternoon, while Aoi practices her bass in a guest house, she gets startled by the 18-year-old version of Shinno from 13 years ago! As if by coincidence, the current 31-year-old Shinno also returns to the town, but he has changed drastically. There are now two Shinno's in existence, but why is the Shinno from the past present?

Sora no Aosa wo Shiru Hito yo revolves around these four individuals as they confront their inner feelings toward each other and make decisions that will affect their lives from here on out.
