Neo Sora is a Japanese film-maker who directed Ryuichi Sakamoto: Opus, a documentary about his father, the renowned composer. The prime minister has taken to claiming that undesirable elements are taking advantage of the earthquakes to indulge in lawlessness. In the school, there is an almost unconcealed racist disdain for students who are not fully ethnic Japanese as well as those who have unorthodox or rebellious views. This is a movie that refuses to give us clear storylines, clear characterisations, clear meanings; even the fierce principal himself might not be quite so strict as all that. It’s a very stylish, thoughtful, heartfelt movie in which regular teen heartbreak might be quite as important as any political commentary.
