Kawasaki Heavy Industries Ltd. reported Wednesday that its full-year net income gained 18 percent after its shipbuilding and industrial plant units returned to profit.

Net income rose to ¥35.1 billion, or ¥21.08 a share, in the year ended March 31, from ¥29.8 billion, or ¥18.94, a year earlier, Japan's second-largest maker of heavy machinery said. Sales rose 4.3 percent to ¥1.50 trillion.

Kawasaki Heavy, which traces its roots back to 1878, delivered liquefied natural gas and bulk carrier vessels won at higher prices, joining larger rival Mitsubishi Heavy Industries Ltd. in returning to profitability from the business.
