Why not? Ask yourself what has been considered the most successful psychological horror game so far? I'm not saying other people don't make any great ones(eternal darkness is IMO one of the best psychological horror games out there).
There's kind of a reason for things being inspired by source material not to be exactly like the source material, they even created a word for it, plagiarism, and at least ripping off to a lesser extent.
Obviously but that's not what im saying. I just meant that it doesn't really matter if it's inspired by western horror because it's nothing like that style at all. Things can be inspired by something and still be similar to the source material without plagiarizing or ripping off of it by the way.
Once again, not really... You also just contradicted yourself entirely, the only reason cultures SEEM to have different styles of horror they're known for is because most people just focus on the here and now. It's not like any particular area has been following one formula for ages- the 90s and early 00's were all about the slasher revival craze, while at the same time a lot of thrillers and psychological horror movies were being put out, where as now- the torture porn is sort of on its way out again now that the Saw series is done with and it's back in with the SPEWKY GOSTE STERIES OMG WATS AROUND THE CORNER.
Eh, nah i haven't contradicted myself actually. You're completely missing the point. Of course no area has only followed ONE formula(who even said that?) But there really are styles of horror that each area is more known for whether you believe it or not. Japanese horror is known to focus more on psychological horror more and ghost
And no that doesn't mean that japanese horror is better either. Styles of horror are influenced by cultures. And yes every culture goes through trends in horror but the trends are different and influenced by culture:
"Japanese horror movies draw on thousands of years of folklore, ghost stories, supernatural myths, and tales of honor and loyalty.
Movies like 1954's Godzilla grew out of Japan's World War II experience with the atomic bomb and were concerned with mass destruction. The 1960s, though, saw a spate of artfully made ghost stories.
"These were safe, distant fantasies for audiences that felt secure in their community," said Stuart Galbraith IV, a film historian who lives in Kyoto, Japan"
"Today's Japanese horror filmmakers, many of whom grew up in the 1980s, may not have the same connection to history. As a result, their movies deal more with the breakdown of reality, of families, and of the mind.
"The world has become a much scarier and more irrational place in the last few years," Macias said. "These films, on a subconscious level, are about dealing with the unexplained."
The Japanese thriller Ringu spawned the successful U.S. remake The Ring in 2002. The movies tapped into contemporary Japanese anxieties about mass media with its story about the vengeful spirit of a little girl who kills people through a haunted videotape.
"Films like Audition, [in which a widower screens potential new wives], Ringu, Ju-On and others touch on sadism, torture, eroticism, revenge, and other themes that are psychologically disturbing as well as just plain scary," said Steve Ryfle, author of Japan's Favorite Mon-Star: The Unauthorized Biography of Godzilla."Horror, Japanese Style: Beyond "The Grudge"

I'm not saying that everyone doesn't go through trends in horror, but the trends are different and can lead to different approaches to horror. Which can lead to certain cultures being known for certain styles more. Simple.
