Takashi Yamazaki's World War II drama "Eien no Zero (The Eternal Zero)," whose pilot hero joins the tokkōtai (kamikaze) suicide squadron in the closing days of the war, has soared to the box office heights since its Dec. 21 release. After ranking No. 1 in the charts for eight weeks in a row, the film now looks likely to finish its run with more than ¥8 billion, making it one of the 10 top-grossing Japanese films of all time.
