It looks like Universal Studios Japan will be hosting a Halloween Horror Nights event this year.
The event will feature a kid-friendly Halloween-themed parade during the day and more sinister events at night once the sun sets. It also looks like zombies in the photo, possibly something to do with Resident Evil.
There is also another event with an age limit, 15 and up. From what I can gather it will be called “Trauma,” and will feature a waiver for guests to sign and will most likely be an uncharge event where guests “test their fears” or something along those lines.
The event will also include Chucky, AVP (Alien vs. Predator), Freddy, among others.
