Although Japanese in origin it is an old and almost universally used

That isn't what I meant. Yes the term tsunami is "universally used". My
point was that whether an event is called a "tsunami" or a "tidal wave"
may depend on where the event occured.

No. It depends on when you were born. If you were born before 1960, you
probably call it a tidal wave.
