We, Ocean Cask Lease Co. Ltd. ( our former name), started operation in 1977 with the main business of owning, leasing and maintenance of CASK for the transportation of the spent nuclear fuel.

We have been expanding our business area and our technical level has now been highly appreciated by the customers.

In 1994, our company name was changed to OCL CORPORATION and our efforts have been much focused toward the company goal so called "Total CASK Engineering Company".

Aware of that we are working in the nuclear industry, we are prepared to make efforts to advance our technical skills and satisfy our customer needs.

We are looking forward to your continued support to us.
