Lost Judgment (known in Japan as Lost Judgment: Sabakarezaru Kioku (Japanese: LOST JUDGMENT：裁かれざる記憶, lit. Lost Judgment: Unjudged Memories) is an action-adventure game developed by Ryu ga Gotoku Studio and published by SEGA in September 2021 for XBOX and PlayStation consoles. The PC version was delayed due to a dispute between SEGA and the voice talent agency Johnny's over actor Takuya Kimura's likeness appearing in a PC game. This was apparently resolved however, as both Lost Judgment and its predecessor Judgment were released on PC simultaneously via Steam in September 2022. Lost Judgment follows protagonist Takayuki Yagami (played by Kimura) as he investigates a high school in the fictional Isezaki Ijincho district of Yokohama, where a student teacher was murdered four years after bullying a classmate to the point of taking his own life.
The following weapons appear in the video game Lost Judgment:
The archetypal Makarov PM pistol, which has appeared in every mainline Yakuza game to date (as well as Judgment), once again makes a return. As always, it features an extended barrel and ring hammer. An RK thug is seen with one in a scene where Yagami is tied up (although he doesn't use it in the subsequent boss fight). In game, the Makarov starts to be used by gang members in random battle encounters from Chapter 9 onwards. It also appears in the picture for the "EX Gun Riposte" ability unlock. In The Kaito Files DLC, Kaito can learn a similar move, called "EX Farewell To Arms."
Smith & Wesson 3913
A Smith & Wesson 3913 is seen with RK, especially with its leaders (and Tokyo Metropolitan Police Public Security Bureau) Higashi Soma. Mikiko Sadamoto, a major character in The Kaito Files DLC, also has one.
Smith & Wesson 3914
An RK thug in one cutscene has a Smith & Wesson 3914, which is the same as the 3913, except it features a blued finish.
Nambu Model 60
As always, the police officer character models feature holstered Nambu Model 60s. Of note is the lanyard ring and distinctive handgrip cutout.
Nambu Model 60/Smith & Wesson Model 36 hybrid
This hybrid is seen with two RK gangsters posing as uniformed TMPD officers sent to assassinate Akutsu after Yagami and company beat him and his posse in a fight. The differences between this gun and an actual Nambu have been thoroughly explained on IMFDb pages for other Yakuza-universe games.
This Remington 870 model is used by virtual thugs in the Dice & Cube VR minigame. As usual, this model features a front piece linking the magazine tube and barrel, like the Remington Model 31. For some reason, the thugs aren't holding the front by the pump handle.
The Baikon Rairyu faction of the Motorcycle Club launch fireworks at other bikers using "fireworks launchers." In reality, these are simply the rocket launcher model from every other Dragon Engine Yakuza game (and Judgment): the Panzerfaust 3-based rocket launcher from Binary Domain with the warhead removed.
Generic hand grenade
This generic hand grenade model appears again from the previous Judgment game. This time, it's seen in the Dice & Cube VR minigame.
In the fight with optional boss Koga, he uses stun grenades based on the Model 7290 Flashbang grenade seen in previous Yakuza games.]]
Drone plasma gun
As with the previous Judgment game, a drone-mounted plasma gun is used to shoot other drones in the Dice & Cube VR minigame.
Leaders of the "Ghost" faction of the Made in Heaven biker gang have motorbikes with not one, not two, but four Gatling guns that appear to be based on the M134 Minigun. The model itself appears to have much shorter barrels (so as to properly fit on a motorbike) and lacks any sort of visible ammo feed. The weight and recoil of such guns mounted so high up on a motorbike would undoubtedly have significant performance and handling implications were one crazy enough to try attempting this in real life.
A number of ranged weapons can be developed for the tournament robots in the Seiryo High Robotics Club. These are small models that resemble generic firearms.
An inert round is one of the items used for crafting in game. It is erroneously called a "bullet;" the bullet is strictly speaking the front part of the round that actually gets fired out of the barrel. This, along with the shell casing, primer, and charge, are what make up the round (although in the case of an inert round, the primer is fired or deactivated and the charge is replaced with an inert material to replicate the weight of the live round).

Heckler & Koch MP7
M26 fragmentation grenade
As with the Kamuro of the Dead arcade game in Judgment, Lost Judgment's 'Hama of the Dead uses the M26 grenade as the grenade icon.
In one substory, Yagami uses a box to sneak up to a man robbing Café Alps. Before getting into the box, he says "time for some tactical café action!" This is a reference to Metal Gear Solid and the MGS series' tagline "Tactical Espionage Action."
In another substory, a brother-sister duo from Russia by the surname of Kalashnikov set up a ninja dojo in Kamurocho. This is a nod to Mikhail Kalashnikov, designer of the AK-47.
