I can't exactly make out what you mean by comparing the two messages you left. You said 対馬 is pronounced Tsushima, yet 島 is shima or jima. If the Japanese government officially use 対馬島 as Tsushima's official name, it is advised to be shown. Still, I agree with your idea more or less, as you have said that the meaning of Tsushima Island equates with 対馬島.

In reply to what you said just now, I am wasting my time for you in the first place. You were the one who made this ammendment, and I have every right to find out and know the cause for your edit, because you did not make your position clear here in the talk page, and I happen to disagree. There is no law that I can't find out the reason of a certain edit which I disagree (initially).

Had I knew that you feel that it is a sheer waste of time just to make this clarification, I feel that I truly regret that I should have edited as I please without asking for your opinions in the first place.
