!! Fridge Brilliance
* If the intent of the holes was to punish the modern Japanese people for their society, then it worked. People on TV saw the faults, were curious about coming and entered their holes. The government can do all they can to seal the holes and corral them off, which they finally do in the TimeSkip, but that still leaves the horrid mystery for those that were lucky enough to not come and see.
* It's mentioned that some rescue crews tried to go after the people entering the holes but were forced to retreat. They survived intact. Why? Because they weren't the ones being punished.
!! FridgeHorror:
* It takes a keen eye to spot them, but some of the holes are the size of children. Imagine how the parents must feel when their child disappears... [[spoiler:and comes home looking like ''that.'' Assuming they can even walk or talk when they emerge, the psychological trauma alone will have reduced them to gibbering lunatics.]]
** Or, what if the parents, in their own mad desire to enter their holes, bring the kids with them...
*** It doesn't really seem like the holes will admit anyone other than the intended occupant/victim very far, so thankfully this scenario is unlikely to be possible. Unless, of course, the parent forces the child to go in front of them, in which case there's no possible answer to the question that leads to pleasant dreams.
** What if someone was pregnant and gave birth in their hole? Yoshida and Owaki shared a KissingDiscretionShot in their tent, leading the reader to speculate DidTheyOrDidntThey
** Some of the holes have it where the person has to bend their neck a little. Consider how [[spoiler:they stretch enough that those whose hole was that of normal stance do get their necks bent at some point.]]
** For those looking for a little [[NightmareRetardant Nightmare Retardant]]: [[spoiler:and "comes home looking like ''that.''" may make one think of a parent frustrated at their child. "Oh, you've been playing near those holes again? Well, I did tell you what would happen..."]]
* Only some holes seem to go all the way through. Assuming the holes keep people magically alive during their [[{{Pun}} hole stay]], then anybody with a blocked hole (such as [[spoiler:Nakagaki, unless he was just at the point when his body would have to stretch]]) would end up spending ''eternity''[[note]]or until somebody dug them out[[/note]] stuck in one spot and ''alive''. And, judging from the researcher near the end who comments on the fault on the other side of the mountain being much smaller than the entrance fault, this likely happened to most of the people who went in.
** It's possible that, given the shapes of the exit holes, the other fault is still large enough to accommodate everybody. Let's hope this is the case, anyway.
** Where is it stated that there needs a one-to-one correspondence between entrance holes and exits holes for everyone to get out? Maybe some of the tunnels run into each other...
*** Or maybe some split...
** It could be the 2nd fault split some of the tunnels somewhere in the middle. The rest just keep on going, deeper and deeper...
* It may just be the effect of shadows, but [[spoiler:the spaghetti-men who emerge at the end appear much darker than those who entered... most likely as a result of having all their innards squashed until they burst.]]
* In the dream, the holes serve as a means of punishment for [[TheUnreveal "a horrible crime"]]. It's possible that the holes exist because everyone at the site is guilty of doing something terrible.
** Or, perhaps, the past-people are dicks, and just want to get their spiteful revenge on all the future people who have survived the collapse of their civilization.
*** Yet, how would they even know what future people would look like? Unless they can see into the future, or ''[[UnseenCharacter something]]'' was telling them to.
*** Possibly the modern victims of the holes are the reincarnations of the original criminals, and look the same as they did in their past lives.
* The holes are angled slightly downward so people go in. As part of the silhouette, there's a big pointy piece of rock pointing at the crotch. It's like if someone turned a wooden horse into a ''slide''.
** What's so creepy about that?
** You... don't find anything additionally unnerving about all the rest of the stuff happening while sliding down a big pointy wedge jammed up into your genitals?
*** Seems they thought op meant a wooden rocking horse, rather than the wooden horse. The wooden horse is a torture device that often injured the genitals. It was triangular in shape and the person was forced to sit on one pointed edge. Now, imagine that, but with rough stone instead of wood, and instead of sitting on it, the person's dragged across it.
*** They do keep their underwear on, so it's probably not ''that'' bad... relatively.
* When you think about it, the best possible outcome of someone passing through Amigara Mountain would be their death when they came out on the other side. More likely, though, given the fact that whatever created the holes keeps them alive for ''months'' without food and water while they creep through, they're forced to go through the rest of their unnatural lives as the deformed creatures who exit the mountain. Assuming that they're still able to move at all, they probably won't be able to walk or to do much of anything other than lay on a hospital bed and writhe in wordless agony.
** Lets just hope pain killers work.
* How do we know that when the [[spoiler:spaghettified]] people come out [[spoiler:(assuming they're still alive)]], they don't feel the urge [[spoiler:to re-enter the distorted holes, having the reverse effect and mutilating them back to a [[BodyHorror somewhat]] human-looking shape, only for them to go back in, causing an infinite loop of torture and mutilation]]?
** As it was revealed in his dream: [[spoiler:"The walls were carved in a way that kept you from retreating."]] So don't worry, you aren't going back to normal.
** [[spoiler: These deformed people ARE still implied to be alive the entire time. But yeah once you go through the normal-shaped holes, you are permanently changed once you get out on the other side.]]
* Maybe the reason Amigara Fault was not closed off immediately was that some of the people who were sent to close it off found their holes instead…
** It's more likely a consequence of the enormous scale of the fault (it takes up an entire mountainside) and the compulsion people feel to enter. While roads could be blocked and police set to guard it, it's just too large to realistically patrol in a way that would keep someone determined to enter from reaching their destination. Which means, of course, that anyone who sees their hole however briefly is doomed in the long run, and that no one can save them.
