 The first-edition series of Viz trade paperbacks retained the same title and subtitle but reduced the page size to approximately ISO A5 dimensions (14.5x22.5 cm, or 5⅝x8⅞").After volume 12, the first-edition A5 series was discontinued.Subsequently, Viz issued new volumes and reprints of older volumes in the "Action Edition" second-edition format, with the simple title "InuYasha" and slightly smaller pages (12.8x19cm, or 5x7½").
