It's Shah Rukh Khan Vs Salman Khan again at the box office. After Salman's "Ek Tha Tiger" it's now Shah Rukh Khan's "Om Shanti Om" that has been released in Japan.

Kabir Khan's blockbuster film "Ek Tha Tiger" was premiered in northeast Asian country last week with Japanese subtitles, while Farah Khan's 2007 film "Om Shanti Om" was released on Saturday, 16 March.

Kabir Khan flew to the country last week after he received an invitation from the Japanese distributors Nikkatsu Corporation. The director and the distributors have decided to release the film on 20 April, IANS reported.

 But now, Eros International has planned to release "OSO" in Japan a month before "Ek Tha Tiger".

Eros International has revealed that the 2007 blockbuster film starring Shah Rukh and Deepika Padukone will be released on 16 March. The film will be titled as "Koi Suru Rinne". The premiere of the film happened on 13 March and director Farah Khan was present.

The film will get 15 print screens as compared to two or three screens in Japan. It is speculated rushed the release of "OSO" only after Yash Raj decided to open up the Bollywood market in the country. But Eros maintained that the release of "OSO" is nothing to do with the release of "ETT".

"Where and when did Japan come into the picture? When Yash Raj took the initiative by flying Kabir Khan to Japan to open up the Bollywood market in the country with 'Ek Tha Tiger'. Eros immediately planned a rush-release of 'Om Shanti Om'," a source close to both the actor said.

"Why a seven-year old film now? Two reasons. One, because reincarnation is a big high for the Japanese. And two, because a Shah Rukh-starrer needed to enter the market before Salman's 'Ek Tha Tiger'."
