Someone had better warn him not to jump on the seats.

Tom Cruise is hoping to impress his Japanese audience by chartering an entire 1,300-seater high speed "bullet" train to take 150 fans on a trip from Tokyo to Osaka on Wednesday.

The two-and-a-half hour train ride is part of the publicity campaign for his latest film "Mission: Impossible III," which premieres in Japan next week.

But any repeat of the actor's couch-jumping episode from the television chat show "Oprah" last year would likely irritate the hygiene-conscious Japanese, who are careful to keep their shoes away from upholstery.

Cruise plans to chat with each passenger individually and have photographs taken with them, according to a spokesman for film distributor UIP.

The actor topped Forbes magazine's annual list of powerful celebrities this week, despite criticism of his occasionally eccentric off-screen behavior, including jumping on a couch when telling chat-show host Oprah Winfrey about his girlfriend, Katie Holmes.
