Japan's Izumo Helicopter Carrier heads to the S. China Sea.

Japan plans to dispatch its largest warship on a three-month tour through the South China Sea beginning in May, three sources said, in its biggest show of naval force in the region since the second world war.
China claims almost all the disputed waters and its growing military presence has fuelled concern in Japan and the West, with the United States holding regular air and naval patrols to ensure freedom of navigation.
The Izumo helicopter carrier, commissioned only two years ago, will make stops in Singapore, Indonesia, the Philippines, and Sri Lanka before joining the Malabar joint naval exercise with Indian and US naval vessels in the Indian Ocean in July.

It appears that the Japanese are slowly but surely heading back to their imperialists roots. If that is the case, I wonder what that means for the region and the world.  Is a militarized and aggressive Japan (to counter the Chinese) as big a worry as many in the region feel?  Is a re-invigorated Japanese military more worrisome than the Chinese?
