I love this but somethings wrong

I think this is amazing.
But I just wondering that why there is "Sea of Japan" in the Earth.

As a science teacher(especially earth science), I really want to make the best use of this app in my class.

So I think there should be a change to "the East sea" instead of "Sea of Japan"

With love & respect
Thank you for making this unbelievable application.
