Japan has approved a second round of shipbuilding capacity investments under its Shipbuilding Industry Revitalisation Fund, authorizing up to ¥98 billion, about $635 million, in government support for five plans led by Oshima Shipbuilding, Kawasaki Heavy Industries, the Shin Kurushima Dockyard group, Naikai Zosen and Mitsubishi Shipbuilding. The projects are expected to generate about ¥280 billion in public and private investment over roughly the next decade. Combined with three plans approved on September 4, the program now covers eight projects representing around ¥900 billion in planned investment and up to approximately ¥311 billion in government support. The funding is aimed at automation, labor-saving production equipment, dock and berth improvements, cranes and other infrastructure as Japan works toward raising annual shipbuilding capacity from roughly 9 million gross tons to 18 million gross tons by 2035.
