Speaking of maps, some American textbooks are changing the name of the sea between Korea and Japan from Sea of Japan to Sea of Japan (East Sea). According to a chosun.com article, one publisher, Prentice Hall, had already changed the name to East Sea (Sea of Japan).
Sea of Japan -> Sea of Japan (East Sea) -> East Sea (Sea of Japan)
One would think there's a textbook committee that keeps geographical names consistent throughout all U.S. textbooks, but apparently there isn't.
I wonder when they'll change the name to simply East Sea or whether this is even a consideration...
