Which is Japan's northernmost prefecture?

Hokkaido is my favorite part of Japan. Before it was island of native Ainu people, now they are one small minority group there.

general rule for colonial settlers is to discriminate, oppress and expel natives from their lands

I think it's really neat they put a railway under the water I wouldn't ride it id be worried the entire time of earthquakes and I can hardly breathe when in a tunnel or on a bridge!

banjo, Any idea what a prefecture is? I have idea

banjo, Think because the word ' Prefecture ' is not familiar in the West. I believe it defines Local States USA/ Counties in England / and other such Regional Governance. ..Please advise and correct me

couldn't understand the question
