Allow me to conclude my trilogy of columns regarding the word "gaijin" this month by talking about the damage the concept does to Japanese society. That's right — damage to Japanese society.

I previously mentioned the historical fact that "gaijin" once also applied to Japanese — to "outsiders" not from one's neighborhood. But as Japan unified and built a nation-state, it made its "volk" all one "community," for political and jingoistic reasons. Anyone considered to be Japanese became an "insider," while the rest of the world became "outsiders," neatly pigeonholed by that contentious term "gaijin."

However, old habits die hard, and "outsiderdom" still applies to Japanese. Even if not specifically labeled "gaijin," the effect is the same: If Japanese aren't from "around here," they don't belong, and it's destroying Japan's rural communities.
