I found some errors in your site about japan.   Do you seriously think that the sea belongs to Japan? Are you familiar with the area? I think you don't. So I suggest that  you should change to the name of East sea. I hope that you are the wrong change the name of the Sea of Japan,  accurate names to East  sea. East Sea name internationally, historically correct name and title Japan as the wrong name.   Hence, you should follow international rules and change the wrong notation.        

This includes Dokdo and Ulleungdo off the East Sea is owned by the Republic of Korea don't belong to Japan. Therefore, you are in not rules of international law as they like Japan marked the beginning of the designation as East Sea should be changed.  This is an important message I want to convey to you.
