Ghosn isn't the first executive in Japan to ever be arrested. But maybe the police felt the stakes were too high. During the Livedoor scandal, Horie had to post a 300 million yen bond for his temporary freedom, and that was for an "internet company". How much would Ghosn's bond need to be in comparison? Not saying that this is the right way to go about things, but it feels at least consistent.
