Infinite Tunnel

The Infinite Tunnel is in modern-day Harrisville, between Grandma's house and Fullface Rock. You can find rare Yo-kai inside.

Tunnel Location

The Infinite Tunnel is in present-day Harrisville. It is east of Mt. Middleton. You can enter it once per day. It reopens at 6AM on your 3DS clock.

Tunnel Information

Each time you go through the Infinite Tunnel, you reveal more of a story.

You can go forward in the tunnel, but not backward. The farther you go, the more likely you are to encounter rare Yo-kai.

However, each time you go through the tunnel, it can change in length. Certain actions can make the end of the tunnel get closer or farther away. In addition, going through a door will make you leave the tunnel.

Each day, the maximum distance that you can go in the tunnel is about 1000 yards more than the maximum distance that you went the day before. After you have gone 20,000 yards in the tunnel, the tunnel becomes truly infinite. At that point, the exit will only appear if you shorten the tunnel by pressing a switch or by answering a question incorrectly.

Yo-kai

If a Yo-kai is standing in the middle of the tunnel without moving, it will attack when you try to go past. If a Yo-kai is walking toward you, you can talk to it and choose whether to battle it or not.

You can encounter rare Yo-kai the farther you go through the tunnel, such as:

  • Auntie Heart (favorite food: Veggies)
  • Count Cavity (favorite food: Ramen)
  • Cruncha (favorite food: Veggies)
  • Damona (favorite food: Candy)

The Tangler is a man with a dog who sometimes appears in the tunnel. He asks you a question, and based on your answer, the tunnel might get shorter or longer. The following table shows his questions, as well as the effects of each answer.

Other Choices

The following table lists other choices you might face as you go through the tunnel.

Tunnel EncounterWhat to Do, and How it Affects the Tunnel
Train (Infinite Railroad)

Sometimes a train will stop in front of you. If you decide to ride the train, it will randomly take you either closer to or farther away from the exit. If it takes you closer, it increases the number of yards you have traveled. If it takes you farther, it decreases the number of yards you have traveled. If you don't take the train, it has no effect on the tunnel length.

I don't recommend taking the train, because even if it takes you farther through the tunnel than your previous record, you will miss opportunities to make the tunnel longer, so the exit might appear sooner than it would have if you had not taken the train.

Emergency Exit (door with a green sign over it) When you check on it, you can choose to go through it or not. If you go through, you will leave the tunnel, with a chance of having a Yo-kai battle first. If you hear radio static just before you go past an emergency exit, that emergency exit will have a Yo-Kai behind it. The radio static is not part of the background music. If you are running, your stamina gauge will also flicker when the radio static sound plays.
Emergency Exit #13 Check on each emergency exit that you pass. Each one has a number. If you go through Emergency Exit #13, you will fight the rare Yo-Kai, Neighfarious.
Door with no sign over it If you go through it, you leave the tunnel without fighting a Yo-Kai.
Wall switch Has a random chance of making the tunnel shorter or longer.
Vending Machine When you put money in, there is a random chance of fighting Yo-kai or getting an item. You are more likely to encounter rare Yo-kai or get rare items if you put in more money.

After you go past, they might suddenly reappear and temporarily transform you into one of them, causing you to move very slowly until you return to normal. Note: this might only happen if you are running.

Here is a video of a traditional dance performance with some hyottoko masks.
