Above is a recent promo video features Japanese celebrities being scared at the park. You can see the higher level of detail and scares they get compared to our walking costumed monsters.

They're getting their own version of Alien Vs Predator this year with horror film connections. Freddy Krueger -The Night Killer and Chucky has Chucky's Horror Factory 2. They also have a maze based on The Ring. Why not stick with the classics. Who really wanted The End as a maze this year at Universal?
They have their own ideas, Trauma- Laboratory of the Worst Terror, which has a 15 and older rating. With that they have Street Zombies all around their park.
For long time fans of the site and for certain anime lovers the icing on the cake is a Ghost Stories maze based on the anime. Over there it was a simple children's anime much like Goose Bumps or Are You Afraid of the Dark. Translated over here it was one of the best comedy animes as it was re-dubbed to make its ghost hunting children stars more foul-mouthed than South Park. I'm sure their version won't be as funny, it will be a school themed maze to spook you.
For younger kid during the day they have a carnival attraction with Trick or Treating and a costume party.
