Alice in Borderland Season 1 Episode 1 Recap: Three Friends Walk Into an Empty Tokyo
Alice in Borderland (今際の国のアリス), Season 1, Episode 1 Netflix · Created by Shinsuke Sato · 2020
A jobless gamer, a fired bartender, and a skipping IT worker hide in a bathroom stall and walk out into a Tokyo with no one left in it.
Arisu (Kento Yamazaki) has just left home. His older brother called him a parasite. His father already washed his hands of him. Standing on the Shibuya scramble with Karube (Keita Machida) and Chota (Yūki Morinaga) — one freshly fired, one ducking out early from work — Arisu says he wishes he could go somewhere unknown. The episode takes that wish seriously and punishes it immediately.
Shibuya empties between one heartbeat and the next
The three of them are hiding in a bathroom stall, fleeing the police after Karube set off fireworks in the middle of the scramble crossing, when the power goes out. Arisu steps outside to check.
The streets are empty.
Not thinned-out empty, not late-night empty. Empty in the way a city never actually gets. No cars on the expressway. No pedestrians. No ambient sound. Arisu walks through the Shibuya 109 area, past dark storefronts, across intersections where traffic signals have gone dead, and nothing moves.
When he finds Karube and Chota again, they stand in the middle of the scramble for a few seconds. Chota says he doesn’t have to go to work. Karube says they can eat and drink whatever they want. Arisu is the one who recognizes that something is badly wrong, but even he can’t identify what. The world they wanted to escape from has simply been removed, and the three of them are standing in the negative space it left behind.
Then the signs appear. “WELCOME, PLAYERS.” Arrows lit in the dark, pointing toward the GM Building.
The first game runs on rules that keep shifting
A phone appears at the building entrance — one per person. Inside, another player is already waiting, a young woman who introduces herself, then warns them not to go any further.
They go further.
The game is called “Dead or Alive,” difficulty Three of Clubs. The rule is a single sentence: select the correct door within the time limit to leave the building. There are two doors in each room. One says LIVE. One says DIE.
The first choice is easy. Arisu reads it almost before anyone asks. A skeleton on one side, a neutral door on the other — “I wouldn’t choose the skeleton.” Everyone goes through the LIVE door and the floor drops open under the young woman who picked up a phone at the entrance. She falls.
The second choice is harder. The time limit has shortened by ten seconds. The young woman who fell is dead on the floor below. A different player, a stranger, argues that someone has to open the door so the rest can know whether it’s safe. He is making the rational case for human sacrifice and he believes it completely. When Arisu refuses to push anyone forward, the stranger calls him a coward. When Arisu tries to open the door himself and freezes, the stranger calls that proof.
Karube opens the door. Both he and the stranger survive. The time limit shortens again.
By the third room Arisu’s hands start working. He noticed the BMW 523d parked outside. He measured the building using the length of his own foot against the floor plan on the evacuation map. He knows the building is square, roughly twenty meters per side, which means nine rooms per floor. He draws it out on a piece of paper Chota hands him and eliminates rooms by process of elimination.
The door that says LIVE is a trap. The “Die” door leads forward.
Karube says “you always said there’s a solution in every game.” Arisu says this is not a game. But his hands are doing what they do in games anyway — checking measurements, counting steps, building a map from incomplete data. The part of him his family dismissed as useless is the only reason any of them survive.
The maze runs out of time on purpose
Room by room, the limit shrinks. Two minutes, then one fifty, then one forty, then further down. It is not a puzzle getting harder in complexity — it is a puzzle designed to see what happens when people have no time to think. The stranger dies in one of the later rooms, not because he chooses wrong but because he freezes at the last second and the fire takes him.
In the final room, Arisu almost loses the thread entirely. He has been mapping the floor, but his map has a gap. He stops moving. The others argue. There is thirty seconds left.
Then he asks Chota about a video.
Chota filmed the first room on his phone. Arisu watches the footage and catches what he missed in real time: the room where the young woman fell has no exit door on the side he expected. Which means that room is not square. Which means his nine-room grid is wrong. Which means there is a room he has not accounted for.
The “Die” door leads out. The “Live” door was always a wall.
Ten seconds on the clock. They run.
Game clear.
Outside, the three of them sit on the pavement. The only other survivor from their building — the man who called Arisu a coward and survived on Karube’s gamble — says quietly that this is retribution. He does not explain for what. Then the game gives them the rules for everything that comes after.
Each survivor receives a three-day visa. A countdown clock, laser-branded somewhere on their arm. When the visa expires, they die. To earn more days, they have to keep playing.
The man tells them there is no end. He says he has been playing long enough that his visa runs out today. He sounds less like someone who has given up and more like someone who simply ran out of fight. He walks away from the building as the numbers on his arm reach zero.
What works
- Arisu’s problem-solving pays off something concrete. His family’s contempt for gaming skills has a direct answer in this episode, and it is not triumphant — it is frightening. The skill saves them. It does not mean anything has been fixed.
- The time-limit compression creates pressure that is almost physical. Each room asks for something slightly beyond what the last room required, and the shrinking clock does not give anyone room to catch their breath between solutions.
- Karube opens the door instead of fighting about it. That decision is entirely in character — he has been doing reckless physical things to solve problems all episode — but it still lands because the episode has established that the other option is to stand there while everyone dies.
- The GM Building setting keeps the spatial puzzle coherent. Arisu is reasoning about a real floor plan with measurable constraints, not solving an abstract riddle.
- Chota’s video is planted naturally in the chaos of the first room, before the audience knows it matters. The payoff does not feel like a cheat.
What stumbles
- The young woman in the entrance exists to die in the first room. She gets a name, a warning, a phone. Her death establishes consequences, but her character never has time to register as anything other than a demonstration.
- The stranger who advocates sacrifice disappears before the episode ends without any accounting for what his logic cost. He is right about the mechanics and the episode does not entirely decide what to do with that.
- The transition from “power outage” to “the entire population of Tokyo is gone” happens without any beat where the full horror lands. The episode moves straight from confusion to spectacle, and the emotional weight of an empty city does not quite accumulate before the game begins.
What this sets up for Episode 02
The visa system is the real trap. Winning games is not a path to safety — it is a path to three more days of having to win games. The man who told them this is dead before he finishes explaining. Episode 02 needs to establish what Arisu, Karube, and Chota do with the knowledge that the game does not end. Whether Arisu’s skills will hold when the difficulty of Clubs cards runs out and something harder arrives.
