In contemporary society, shipping and fishery industry tend to use Japanese language or Japanese style terminology extravagantly. It becomes a reason of preventing the communications between crews who have been working for many years and the beginners in the ships. Also the crews cannot easily understand the contents of the manuals that is explained in only Korean language. For this reason, the foreign employee have to study Japanese style terminology before begin start their work. I strongly believe that this is one of the major national contempt. It is reasonable to expel Japanese style terminology from the vessel if possible to enable free communications to each other. I inspected and examined about purification of 125 Japanese style terminology that is already examined in the fishing vessels 11 years ago. So, I expect this paper is a research for the eradication of the Japanese style terminology in the Korean fishing vessels.
