428: Shibuya Scramble is a visual novel adventure video game produced by Koichi Nakamura with Jiro Ishii serving as executive producer, developed by Nakamura's company Chunsoft, and initially published by Sega, originally in Japan for the Wii on December 4, 2008. The game was ported by Spike to the PlayStation 3 and PlayStation Portable in September 2009. A version for iOS and Android was released in November 2011. PlayStation 4 and Microsoft Windows versions were released internationally in September 2018.
428 is set in the Shibuya ward of Tokyo where the narrative is presented using a combination of scrolling text, live action stills and video sequences. The game shares many story and gameplay elements with Chunsoft's 1998 sound novel game Machi, the most prominent being the locale, Shibuya. Although Chunsoft does not openly state 428 is a sequel, the game contains numerous references to Machi, and an early marketing slogan reads "Breaking a long silence, Shibuya gets going again."
The game has received high praise from critics, earning a perfect score in Famitsu Weekly, Japan's largest circulating video game magazine, as well as acclaim from international publications. The game also features a special scenario contributed by Kinoko Nasu and Takashi Takeuchi of Type-Moon fame, who wrote and provided character designs for it respectively. This scenario by Type-Moon got a sequel as an anime television series titled Canaan, which aired in Japan from July to September 2009. A series of four novels based on the game were published by Kodansha between the months of September and December 2009.
A successor to the game, titled Shibuya Scramble Stories, was announced in 2025 by most of the original team under a crowdfunding project.
Gameplay
428 is a visual novel adventure game where players take part in events from the perspectives of multiple protagonists, all acting in parallel with no knowledge of each other. Set in the modern Japanese city of Shibuya, Tokyo, the characters are involved in a mystery that cannot be solved without their interactions, and the plot is advanced by following clues found within the game's text and accompanying video sequences and making decisions on which path each protagonist should follow. Depending on the player's choices, a number of new scenarios become available, which ultimately lead to different outcomes and endings. The game has over a hundred alternate story pathways and 87 different possible endings.
Parallel gameplay mechanic Players read through and switch between multiple stories that take place in the same timeframe, each seen from a different character's point of view. Decisions made in one character's story can inadvertently affect the story of another character in unforeseen ways. The format is similar to earlier non-linear visual novels with multiple perspectives, such as Machi (1998) and EVE Burst Error (1995), and can also be compared to non-linear hyperlink films such as Pulp Fiction (1994), Magnolia (1999) or Vantage Point (2008).
For instance, the game opens with a detective (protagonist #1) waiting for a kidnapper to pick up the ransom money, which is being carried by a girl. Another character, a young man out for a walk (protagonist #2), happens to encounter the scene. Protagonist #2 now has a choice to approach the ransom-carrying girl or not; If he approaches, his story reaches a dead end by being wrongfully arrested, but not only that, the detective's story also reaches a dead end by making the wrongful arrest.
The player's role is to figure out whose actions are affecting whom, and find the right choices to lead every protagonist to the conclusions of their storylines. The game offers a time chart screen where the events of all the protagonists' stories are listed in chronological order.
Blue-colored text is interspersed within the body text. The colored text, called Tips, can be selected like a hyperlink. Tips, when selected, provide a short page of explanatory text, much like a tooltip. Tips can reveal the definition of a technical term, provide some insight on the topic, or just provide a short digression from the story at hand. Red-colored text, also selectable, marks the name of a different protagonist and allows the player to jump from one protagonist to another. Jumping from red text is often the only way to make a character's story move forward.
The game unfolds in a ten-hour period, which begins at 10:00AM of April 28 and ends at 8:00PM. The game is broken up into one-hour segments. Leading every protagonist to the end of the hour unlocks the next hour to be played.
Story A major event that could jolt the world has been triggered in the streets of Shibuya. Five main characters have 10 hours to come together and solve the mystery behind what originally seemed like an ordinary ransom kidnap case.
The game is a crime thriller, but has multiple scenarios that cover several different narrative genres. For example, Shinya Kano's scenario is a hardboiled cop thriller, Tama's scenario is a slapstick comedy, and Osawa's scenario is a psychological horror.

Main story
On April 27, college student Maria Osawa was kidnapped on her way to a mixer, which included her twin sister, Hitomi, and her professor. The kidnappers contacted the Osawa residence and demanded for ¥50,000,000 to be delivered by Hitomi at the Statue of Hachikō in Shibuya. The police force, including Detective Shinya Kano, surrounded Hachiko the next morning to catch the kidnappers. Once contact was made and the kidnapper ran with the case, Kano chased after them. Meanwhile, former gang member Achi Endo witnesses a Man with a Cane and a gun approach Hitomi, and Achi attempts to intercept and take Hitomi to safety. She explains that the kidnappers told her to find and enter a blue van, and Achi agrees to take her there, all while avoiding the Man with the Cane.
At the Osawa residence, Maria and Hitomi's father, virologist Kenji Osawa, receives a threatening email with images of unauthorized clinical trials on an antiviral drug he had worked on for a virus called the Ua Virus. Elsewhere, freelance journalist Minoru Minorikawa offers his services to his former boss, Teuro Toyama, in filling 12 pages for his next issue of his magazine, with the proof deadlined for 8 PM, and enlists the help of novice Chiaki Iso as they search for stories to write.
That same day, an amnesiac girl nicknamed Tama applies for a job in a mascot costume at a sales demo, in order to buy a special necklace. However, her boss Jun'ichi Yanagashita appears to be a swindler, and her costume's zipper is stuck. Minorikawa attends the sales demo, which ends catastrophically, but after a long morning of work, Tama is paid and Minorikawa gets his interview with Yanagashita. With the necklace purchased, she realizes her costume's zipper has gone loose, taking it off and revealing the amnesiac Tama as Maria Osawa.
Kano pursues the kidnappers and eventually is assisted by an American from the US Embassy named Jack Stanley. They find the kidnappers dead in their hideout, attacked by someone named "Canaan." As Achi and Hitomi are pursued by remaining kidnappers, a woman appears, naming herself Canaan and Maria's close friend from overseas, and reveals it's her fault that Maria was kidnapped. They eventually approach the blue van, but it explodes with Achi, Hitomi, Canaan, Minorikawa, Chiaki, and Maria nearby. Maria is held hostage by the Man with the Cane and Minorikawa spies on Stanley and Kano. Stanley reveals he is a CIA agent hunting down a criminal named Alphard, who had infected Maria with the Ua virus, let her loose in the city, and seeks Hitomi to steal the antiviral hidden in her blood.
Achi and Hitomi head to the hospital to check on Achi's sister, Suzune, who has been dying from a heart condition, and had collapsed earlier that day. When the doctor informs his that his father, Daisuke, stated a perfect donor would arrive soon, Achi discovers that Hitomi's blood-type is the rare Bombay blood, a perfect match for Suzune, revealing his father had hired the Man with the Cane to kill her. Kano meets up with Detective Tateno —the Man with the Cane— who holds Maria hostage and reveals that the Endos were his childhood friends, and he seeks Hitomi to cure Suzune. Maria remembers her past, and escapes when Canaan attacks Tateno. Maria, Hitomi, Achi, and Stanley arrive at the Endo residence, where Daisuke reveals that he worked with Alphard but mistakenly kidnapped the wrong twin. As Kano and Canaan arrive, Maria collapses as the virus activates, and Alphard makes contact, offering the password for the antiviral in exchange for a sample of Hitomi's blood.
Achi seeks help from his former gang, the S.O.S., to apprehend Alphard, and with Minorikawa's intervention they accept. Canaan and the reformed Tateno take Maria to the lab to rendezvous with Osawa, while Hitomi, Kano, Achi, and S.O.S. head to the Statue of Hachikō to meet with Alphard: the twins' college professor. They apprehend him, prevent a Ua outbreak in the public square, and obtain the password, but it is revealed that "Alphard" had been carrying a bomb. Stanley discovered the truth: "Canaan" is not the real Canaan, but the real Alphard, and her true target is the laboratory. Stanley rushes to the lab to apprehend Alphard with Tateno's help, Osawa administers the cure to Maria, and Kano and Achi (with Minorikawa's help) stop the bomb using dry ice.
