Got this in the mail a few weeks ago, and was lazy and forgetful about getting one of my co-workers to tell me what it was about--for which I am now kicking myself. Turns out it was a coupon for a free breast exam that was sent to me by the City of Nagoya. They gave me a huge list of doctors I could go to with my coupon to get a check-up for free. Did I mention it was FREE? Because it was. I found out the day before it expired so I wasn't able to take advantage of it, but if there's a next time, I'll be sure to jump on it. Japan, you rock.
