Saraba, yes it has use in Japanese. Its meaning is that of a definitive farewell. The most frequent use is a farewell in the face of a more than likely death, or a farewell to someone you will never see again. It is important to emphasize that in this case, the indicated word is not sarabada . Es saraba da , the common form of the verb ser/estar desu ?? . ???? . Putting both words together in one , is a fairly common mistake of those who do not have much knowledge of the Japanese language. Returning to the word, as with others (as it happens in Spanish with the word bizarro) its use is relegated and the meaning can be modified by those who do not know it. In Japan, the term ??? , has an almost poetic connotation . To get an idea, it would be like the expression Pardiez! in Spanish . It is a term that nobody uses, but that most know and its mention seeks to evoke past times or give a certain connotation to the phrase or situation.
Another missing is the Japanese dictionary. Not used in Spanish, and the truth is that not in Japanese; It is the transliteration of an old farewell ceremonial greeting, which is attributed to the samurai as 12373; 12425; 12400; 12384; ("Sara Da"). Today you can use it as a joke, because it sounds very dislocated. For some mistake see Zarabada, Saravá.
