History

Oshima launched its first ship in 1975. The disruptions in the oil industry of the 1970s caused the company difficulties. Between 1975 and 1979 Oshima reduced its workforce from 1,800 to 785. In response, the company repositioned itself to specialize in building handymax and panamax bulk carriers.
The company has built 400 bulk carriers and delivers about 25 new ships annually to a worldwide client base.. As of March 2018, the company has annual revenues of 116,000,000,000 Yen and a staff of 1344 full-time employees. An additional 660 workers work for Oshima on a subcontracting basis.

The company provides three hull options: single-hull, double-hull, and its own proprietary "Hy-Con" or hybrid hull configuration. Single hulls are available on the smallest and largest of the vessels. Double hulls are available on the smallest and all vessels from to. The Hy-Con configuration is available on ships in the to range.
The Hy-Con design was developed to increase safety and the efficiency of cargo handling on bulkers. This design starts as a standard single-hulled ship. Then, the forward and aft holds are built up to double-hull structures.
