Mike, don't get too worried. A friend of mine who did the JET program was sent to a rather isolated fishing village. If I recall correctly, she was the only foreigner to have been there within living memory, and the nearest big city was too far for regular travel.
She ended up loving every minute of it. It was a great experience for her, and she thinks she had a much better deal than JET people who went to more metropolitan areas.
I know another guy who was posted to a pretty rural area and ended spending a good bit of time around the older men of the village. He had some great stories about getting drunk with these old veterans who still blamed the American aggressors for the Second World War.

My opinion is, in all likelihood, worth exactly what you are paying for it.
