"Why did you come to Japan?" We've all been asked this question. I still can't give a good answer.
I certainly know why I came here, but such a point-blank question, usually from someone you hardy know, calls for an equal and reticent answer. Thus, we tend to say what we think our questioner wants to hear: "I came to work," or "I came to teach English," etc. But our reasons for coming to Japan are likely more profound. After all, most of us could have stayed in our own countries to work. Some of our predecessors came to fight wars, occupy and help rebuild. Others came seeking a better life. But my generation came to study, to teach, to experience or sometimes just to understand their own ancestors.
Some of us are running away from something at home: love, family, or responsibility. Some of us are the first in our family to ever go abroad. Others are living the life their parents only dreamed of. And some of us are doing nothing of the sort. But one thing is for sure: We came to Japan because we wanted to step into a different realm.
