Brad Pitt did it.

George Clooney and Meg Ryan did it.

Bill Murray pretended to do it. And back when he was just a celluloid action hero, Arnold Schwarzenegger was very, very good at doing it.

But none of them does it much these days.

A Hollywood in-house secret, Japanese TV commercials were once talked about with a wink and a shake of the head. Piles of cash were paid to stars willing to peddle anything from whiskey to cigarettes, cars to coffee, instant noodles to cafe latte -- as long as nobody told the fans back home. Hey, did you know Dennis Hopper did one for bath products? How much do you figure Leonardo DiCaprio got for that SUV spot? A million? Three?

Sadly, the days of seeing, say, Harrison Ford guzzling Kirin beer may be over. American stars have not vanished from the Japanese advertising landscape, but their numbers have dropped dramatically since the heyday of the 1990s, when even Mickey Rourke was considered bankable here.

"There are much thinner pickings these days," said Al Soiseth, whose Web site (as in Western stars "pandering" to Japanese audiences) offers a video compendium of Japanese commercials featuring Western actors. Soiseth says there is a dearth of new ads to add to the archive, which is packed with clips of Hollywood's 1990s "A list."

Advertising industry analysts offer various explanations for the decline. With the irrational exuberance of Japan's bubble economy a distant memory, ad budgets have shrunk to, at best, half their former size. Hollywood stars still expecting to pull in $3 million for an afternoon's work trying not to garble a simple Japanese phrase are finding few takers.

Japanese advertisers began using Western actors in a big way in the 1960s, when Hollywood represented the cachet of American culture. But some marketing analysts point out that the Internet and globalization have made American pop culture far more accessible to Japanese consumers and, by extension, less exotic.

"The mystique has faded," said Akihiko Sasamoto, who heads the Asian casting division of Hakuhodo, one of Japan's biggest advertising and marketing agencies. "You no longer have this distinction between foreign artists and Japanese artists. So we don't need to spend a big amount of money on a Hollywood star."

Japanese agencies are increasingly turning to more affordable home-grown talent, especially fashion models, who have been found to trigger higher recognition for the brands they push at much lower cost. Sports celebrities, whether homegrown such as baseball's Ichiro Suzuki or foreigners such as French soccer star Zinedine Zidane, also have taken a big chunk of the endorsement business.

Other Japanese companies have opted to use animated figures or even real animals. Research in the Tokyo area shows that Que-chan, a Chihuahua whose owner is forever taking out loans (at 28 percent) to buy presents for the beloved dog, has had more impact this year than most two-legged stars. Que-chan's series of humorous ads, including one in which he snowboards down a mountain, have been credited with softening the loan industry's image. Meanwhile, the real dog has become enough of a celebrity to publish a book of vanity photos and release a compact disc.

Whatever the reason, Hollywood may be facing more than just a short-term dip in its commercial fortunes. Many in Japanese advertising argue that the decreasing use of American stars marks a cultural watershed in which Japanese audiences increasingly embrace stars and celebrities from Asia instead of the West.

"The Hollywood brand isn't the best anymore, and Hollywood actors aren't effective enough anymore," said Yukio Mori, president of Systrat Corp., a marketing and promotion consultancy in Tokyo. "Consumers are in favor of singers or artists who are familiar, rather than foreign movie stars."

The catalyst for the change, almost everyone agrees, has been Japan's raging love affair with Korean culture that took everyone here by surprise two years ago.

The phenomenon was spearheaded by a drama series called "Winter Sonata," a tragic love story featuring Bae Yong Joon, a South Korean actor affectionately referred to as Yon-sama in Japan. With his baby face and great teeth, Yon-sama, 33, flutters the hearts of Japanese women in their thirties and older, who tell market researchers he rekindles the romantic urges they felt in their youth.

It's a demographic that makes marketers swoon, too. Yon-sama is now the biggest foreign star in Japan. Dozens of Japanese companies are desperate to attach their brand to Yon-sama, or at least to find the next great Korean star.

That's not to say the demand for Hollywood actors has completely dried up. Richard Gere is still popular, pushing everything from condominiums on Tokyo Bay to Dandy House, an exclusive men's spa center.

But with Hollywood's heyday over, its priceless moments are now consigned to the fringes of the Internet. Out there in the digital equivalent of the remainder bin are clips such as two-time Oscar winner Jodie Foster extolling the virtues of an employment agency; Madonna, dressed like a ninja, pushing a brand of liquor called Pure. ("I'm pure," she coos.)

The ads are memorable only in Japan, however. Moonlighting on Japanese TV commercials is one of those subjects Hollywood stars prefer to not talk about in front of their fans. Too much risk in exposing themselves to charges that, despite those appearances on "Inside the Actor's Studio," they were only too happy to sell their celebrity for a quick buck.

The practice was mocked in Sofia Coppola's "Lost in Translation," in which Bill Murray's Bob Harris, a Hollywood actor on the back nine of his career, comes to Japan to make a whiskey ad.

Not everyone in Hollywood sees the humor. Lawyers for DiCaprio, Liv Tyler and Meg Ryan have sent letters to Soiseth demanding he take their commercials off

Soiseth, who says he runs his site for love and amusement -- "I love the way they are always talking about my art, my art" -- acquiesced and removed those actors' video clips. "It would be an interesting lawsuit, and I'd love to see it filed," he said. "But not on my wallet."

Maybe it is the sheer goofiness of so many of the ads that Hollywood stars are anxious to hide. Consider:

Charlie Sheen selling women's shoes, or getting a haircut from a Japanese barber in a spot for Tokyo Gas.

Richard Gere singing "No Woman No Cry" for a Japan Airlines ad promoting flights to the Caribbean.

Michael J. Fox being chased off the grounds of a mansion by a heavy-set maid carrying a broom after he uses hedge clippers to turn a bush into a teddy bear. (The ad was for canned tea.)

Perhaps no one got into the spirit of things as well as Nicolas Cage.

Four years ago, a Japanese company that makes the machines for the wildly popular gambling game pachinko was looking for a way to add a little glamour to the industry's less-than-savory image.

Who better to make you feel better about your addiction to pachinko -- a cross between pinball and slots -- than the star of "Leaving Las Vegas"?

Scene: A packed news conference in Japan.

Zoom in: Cage taking a seat behind a table filled with microphones.

Female Japanese Reporter: "What do you think of Japan?"

Cage (hands waving): "I like all Japan. I like sushi. I like Mount Fuji."

Close-up: On the reporter's pearl earring, which (mysteriously) comes free. It falls to the floor and rolls (like a little pinball) toward Cage. We see him transfixed, with his trademark bug-eyed stare. With his shoe, he flicks the earring into the air and snatches it with his hand.

Cage (screaming maniacally): "I love pachinko!"

Let's see Yon-sama do that.

Brad Pitt, Madonna and Nicolas Cage have all made commercials in Japan, but the attraction is fading.
