If you're interested in the life of Zainichi Koreans in Japan, Kazoku no Kuni is a more recent movie to check out. While GO deals with the issue more from a teenager's point of view, Kazoku no kuni is viewed from a zainichi family's perspective. Take note however that the latter is an independent film so beyond the common theme of zainichi Koreans, these two films are different in terms of cinematography, mood and perspective.
They're both about the experience of ethnic Koreans living in Japan. Go is essentially a coming-of-age movie, while Our Homeland is more of a family drama.
