A play Red Demon written by Hideki Noda has been produced in four versions since its first performance in June, 1996.; in Japanese, Thai, English, and Korean. It seems this play has been effective for more than ten years. This paper examines the reason. This play keeps an exquisite “sense of distance with reality” to politics after 9.11. And the play expressed a kind of “de-borderline-ness”, showing us memory and history.
