Yeah, it was. Since when? The word tango is used for many different places by many different people. But you're talking about a word here, the tango dance and music in purely a White-European dance and form of music. I suppose you didn't know that Tango Province is a region of Japan. The Tango is not Japanese, it's Argentine. The product of European immigrants in Argentina and Uruguay. Some people have proposed that the word Tango originated in Japan and was picked up there by the Portuguese and Spanish sailors. But I don't think so, I think it is just a Spanish word. Because it is.
