Game Overview

Lost Judgment - Game Overview Banner

Lost Judgment, also known as Lost Judgment: Unjudged Memories (ロストジャッジメント:裁かれざる記憶), is a single-player, beat ’em up action-adventure and role-playing game developed by Ryu Ga Gotoku Studio for the PlayStation 4, Xbox One, PlayStation 5, and Xbox Series X|S. Ryu Ga Gotoku Studio is also known for its other titles such as the Yakuza series, including Yakuza: Like a Dragon. Other IPs include Fist of the North Star: Lost Paradise, and Super Monkey Ball: Banana Blitz HD.

Lost Judgment - Game Overview

Lost Judgment is the follow-up sequel to Judgment or Judge Eyes: Shinigami no Yuigon (ジャッジアイズ: 死神の遺言). The whole Judgment series is a spin-off of the Yakuza series, including Yakuza: Like a Dragon, and happens in the same world. The game shares some similar features to Yakuza games, with the exception of Yakuza: Like a Dragon, in terms of its combat system. Lost Judgment will offer both Japanese and English dub voices for the player.


Lost Judgment - Story

Lost Judgment continues the story of Yagami and follows up the events of Judgment. The setting of the game centers on two locations namely Kamurocho, Tokyo (the main setting of the Yakuza 0-5 and Judgment), and Isezaki Ijincho, Yokohama (the main setting of Yakuza 6 or Yakuza: Like a Dragon). Also featured is a high school in Yokohama as another central location in the game.

Lost Judgment - Setting

The game is set in December 2021. Akihiro Ehara is accused of sexual harassment and randomly proclaims that there is a dead body in an abandoned factory in Yokohama’s Isezaki Ijincho district. Saori Shirosaki, the defense lawyer of Ehara, called the private detective, Takayuki Yagami, to help investigate Ehara’s case. While looking through the crucial details and investigating the murder case, Yagami is faced with a question: Defend the law, or enact justice?


Lost Judgment shares similar gameplay from other Yakuza games and carries most of the gameplay features from the first Judgment game. Here is a breakdown of some gameplay systems in Lost Judgment:

Battle System

Lost Judgment - Snake Style

Lost Judgment’s combat system shares similarities with Yakuza 0. Players can change Yagami’s fighting style when fighting enemies. In Lost Judgment, Yagami can now use three fighting styles which are the Crane-style, Tiger-style, and Snake-style. Crane-style is focused on fighting groups of enemies, Tiger-style centers on fighting individual enemies, and Snake-style deals with counter-attacks against armed enemies.

Two Locations: Tokyo and Yokohama

Lost Judgment - Kamurocho, Tokyo

As mentioned earlier, Lost Judgment will feature two locations namely Tokyo and Yokohama. Yagami will start at the red-light district, Kamurocho, Tokyo (a fictionalized version of Kabukicho, Tokyo).

Lost Judgment - Isezaki Ijincho, Yokohama

Then, he will later move to the port district of Isezaki Ijincho, Yokohama (a fictionalized version of Isezakicho, Yokohama) to continue and possibly conclude his investigation.

Trailing and Stealth Missions

Lost Judgment - Trailing Mission

Trailing Missions are the stealth segments of the game. As a detective, Yagami must chase suspects around the city in order to gather leads in solving his case.

Lost Judgment - Stealth Missions with Shiba Inu

This time, Yagami has a Shiba Inu called a “Detective Dog” in his side to help him accomplish stealth missions and acquire suspectful items.

Platforming Challenges

Lost Judgment - Platforming Challenges

Some trail or stealth missions would required platforming from one building space to another. This is to add more variety and challenge in doing these missions in the game.

School Stories

Lost Judgment - School Stories

Within Yokohoma, Yagami will spend time at a high school since it is an important location for his work. With that, he will interact with students in the form of school activities like dance tournaments, science fairs, athletic competitions, and etc. Accomplishing these school stories will reveal a unique side of Yagama’s character.
