Kawashima plays in Belgium for Standard Liege. He's well known around here. Maybe the best keeper in the Belgian competition at the moment.
Last year some supporters, don't remember from which team, vocaled "fukushima" to him, which was a major stir around here. So the joke isn't even original, if it even was back then. Kawashima->Fukushima... killer joke :/
Even before the news got out that this was an especially sensitive thing for him, no one I know thought it was a good joke. I seem to remember the head of our football league made a public apology to the Japanese ambassador in Belgium.
So this could become a bigger story.
