Iwo Jima? Iwo Tou?

硫黄島can be read as Iwojima, or Iwotou, but apparently, from what I know, it was called Iwotou originally. Iwojima is the name given to it by the Americans.

So now, after all these years, it seems that Japan is going to use back the old, original name of Iwotou. So don't be surprised if you start seeing references to Iwotou in the future. It still refers to the same small island.
