Something tells me now is not the time for Japan to start to practice its ancient ways.
And Japan has a strange personality that we do not always understand. Under my pendulum of love theory, the more peaceful and shrinking back a people can be,, the more violent they can also be.
Germans were the epitome of romantic thought, hiking the mountains, eidelweiss, poets and philosphers.
The Japanese are very pacifist,, but they are also motivated by honor and pride and principle (as they define it) in ways we do not always fathom. It could get weird.
