The "exceptional" country who "liberated" Okinawa in reality still occupies Okinawa. Up until 40 years ago, for main land Japanese to enter Okinawa American visa was needed. For Okinawan Japanese to enter main land, they had to obtain Japanese visa. Do Japanese (Yamaton Chu) appreciate Okinawan's sacrifice? Okinawans, like Ainu in Northern Japan are aboriginal people in Japan. I am Ainu who left Japan for an obvious reason. For Japan's ambition, Ainu had to sacrifice our lives in the Northern front of Japan's empire. "Shima Uta" has a hidden meaning. Knowing that, when I hear this song, I can not stop tears coming out from my eyes. "Happiness?" Ayano san is telling us this intolerable tragedy and injustice in such a gentle and beautiful way. Please rest in peace, as we will not repeat the same mistake. I dare not point finger at. I am sure those guilty know and certainly the heaven knows.
