I think this is more of a educational diorama thing than a haunted house, though the spider one could be rather frightening. A fun way to see yokai you may have been told stories about! I wish I knew what they were saying, I'm familiar with many but not the one at 5:30, the dialogue reminds me of the exaggerated enunciations in kabuki theater. You can also hear the Hyoshigi which is part of those performances. I'm not big on spiders but I recall there being spider women, not just giant ones. There must be both, how scary!
6:03 apparently, there’s a Yokai that is disguised as a innocent sign but when somebody picks it up the sign possesses, the man or women, and that person will advertise other people to make them go to the spirit realm
