I'm guessing then they will continue the Protectorate role for a 70 year period if they can get away with it, making Japan free to have a military circa 2015. (70 years based on how many years that are usually placed in regards to the sensitivity of a subjection. i.e. "Raising the Titanic" can't occur until all survivors are no more. Obviously 70 years is a number of "innocent" generations.) Although saying that Germany is reunited before that time period, why not Japan?
