The tension over the disputed territory in the South China Sea is about to escalate to another level: according to a Reuters report, Japan is preparing to to dispatch its largest warship on a three-month tour through the South China Sea beginning in May, in “its biggest show of naval force in the region since World War Two.”
The 249 meter-long (816.93 ft) Izumo is as large as Japan’s World War Two-era carriers and can operate up to nine helicopters. It resembles the amphibious assault carriers used by U.S. Marines, but lacks their well deck for launching landing craft and other vessels.
While China claims almost all the disputed waters despite the regular complaints of other nations in the region, and its growing military presence has fueled concern in Japan and the West, with the United States holding regular air and naval patrols to ensure freedom of navigation, so far Japan’s territorial claims have involved the Senkaku island chain in the East China Sea; that however appears to be changing as Japan seeks to stake a military presence in the contested region.
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 U.S. naval vessels in the Indian Ocean in July, before returning to Japan in August.
Why create another point of Chinese antagonism over the region? “The aim is to test the capability of the Izumo by sending it out on an extended mission,” said one of the sources who have knowledge of the plan. “It will train with the U.S. Navy in the South China Sea,” he added, asking not to be identified because he is not authorized to talk to the media. A spokesman for Japan’s Maritime Self Defense Force declined to comment.
Taiwan, Malaysia, Vietnam, the Philippines and Brunei also claim parts of the sea which has rich fishing grounds, oil and gas deposits and through which around $5 trillion of global sea-borne trade passes each year. Japan does not have any claim to the waters, but has a separate maritime dispute with China in the East China Sea.
Japan wants to invite Philippine President Rodrigo Duterte, who has pushed ties with China in recent months as he has criticized the old alliance with the United States, to visit the Izumo when it visits Subic Bay, about 100 km (62 miles) west of Manila, another of the sources said. Asked during a news conference about his view on the warship visit, Duterte said, without elaborating, “I have invited all of them.”
He added: “It is international passage, the South China Sea is not our territory, but it is part of our entitlement.” On whether he would visit the warship at Subic Bay, Duterte said: “If I have time.”
Japan’s unexpected flag-flying operation comes as the United States is conflicted between taking a tougher line with China and making concessions ahead of Xi’s visit to Trump next month. Washington has criticized China’s construction of man-made islands and a build-up of military facilities that it worries could be used to restrict free movement. Beijing responded in January said it had “irrefutable” sovereignty over the disputed islands after the White House vowed to defend “international territories”.
As Reuters notes, Japan in recent years, particularly under Prime Minister Shinzo Abe, has been stretching the limits of its post-war, pacifist constitution and has been making aggressive pushes for a return to militarism. It has designated the Izumo as a destroyer because the constitution forbids the acquisition of offensive weapons. The vessel, nonetheless, allows Japan to project military power well beyond its territory. Based in Yokosuka, near to Tokyo, which is also home to the U.S. Seventh Fleet’s carrier, the Ronald Reagan, the Izumo’s primary mission is anti-submarine warfare.
