The number of Western movies subtitled in Japanese is rapidly declining as 3-D movies become more common and viewers grow more averse to reading text on screen.

Instead, many theaters are opting to show films dubbed in Japanese.

About 40 percent of the theaters that showed "Avatar," the world's first full-length commercial 3-D film, used the dubbed version. That ratio climbed to 60 percent for "Alice in Wonderland" and about 90 percent for "Toy Story 3."
