Be careful what you wish for.

Japan was not really defensible in the 1940s and it most certainly isn't defensible today. It's too densely populated and easy to attack so Japan would be insane to fight an offensive war that threatened the United States (it was insane in 1940, too). So long as the United States is the defensive umbrella for Japan, the North Korean Chia-Dictator could threaten Japan and that would give Americans the hard choice of going to war to save Japan. I'd rather let the Japanese decide when nukes are warranted for their own defense.
