'Iron Man 3' to Become First Film to Play in 4DX Format in Japan

Iron Man 3 will be shown starting April 26 in 4DX at a theater in Nagoya, central Japan, operated by the Korona World chain, which plans to screen 12 titles a year using the new format.

"Fourth dimension" effects utilized by the system include strobe lights and equipment in the ceiling that can drop bubbles down upon the audience, who will pay a $13 (1,300 yen) premium for 3D versions and $10 for 2D films, on top of the regular ticket price. Average admission price in Japan in 2012 was $12.50.
