In the past century Japan was a super power and years before that a nation with a naval might. After
World War 2 Japan tasted humiliation, defeat and reform; the once mighty nation became an industrial country with rich economy. Japanese tasted the bitterness of War and they dislike it, hate it and much as possible avoid it. But the Rise of Chinese military and its Navy sowed fear to neighboring countries especially to those countries with rights on the disputed islands and shoals. The Samurai spirit of the Japanese Army started to wake-up and decided to Re-arm again. This scenario happens before, it is like repeating the history -- before Japan shocked the World's Navies with their Yamato-class Battleships and Carrier. Today what could be in their minds to challenge the advance battleships of China? Japan is expert in making gigantic battleships in secrecy, they are the most discipline people in the world.
The Re-arming of Japan is not to face off with China, but rather to bring balance of power in Asia and that is what Philippines, Vietnam and other countries thought of it. America seems agreeing to the decision of Japan though it sparks tension with China. America as what everybody thought as the protector of democracy in Asia and pledged to help those small countries that are involved in the disputes in South China Sea. But America seems unwilling to help in giving assistance to these small countries in protecting their sovereignty.
And Japan steps in to be that one -- Rearming their country, improving their Navies would at least makes China to re-think whatever plans they have in their minds in taking those disputed islands.
China is getting more powerful each passing year, every after few months they introduced new weapons, ships or planes and missiles, what chances could these poor countries who are fighting for their sovereignty could have. If War would brake, it will never be on the lands but on the seas and air, it will be an expensive war -- where bamboo sticks and guerrilla warfare would never get a chance to get a kill.
