The Death March of Young Kindaichi File 3 - S2-E3
Plot hole: Kindaichi bases his solution on a fact (there was a certain object on the elevator together with the victim) he couldn't know about, since Li did not mention it (and if he did, he would have been on the right track to solve the mystery himself).
The Death March of Young Kindaichi File 3 - S2-E3
Continuity mistake: When Kindaichi shows the newspaper explaining to Kenmochi (and the audience) the mystery behind Akechi's death, he holds it in close-up with his finger between the second and third character from the right, the third and fourth in the next shot. (00:16:25)
The Death March of Young Kindaichi File 3 - S2-E3
Continuity mistake: When the police blocks the alley where Matsuoka was killed, the corpse is gone, but the first shot of Li in the alley shows the body being wheeled away in the foreground. (00:09:15)
The Death March of Young Kindaichi File 3 - S2-E3
Continuity mistake: After the flashback to the event of 18 years earlier, there's a side view of Matsuoka's face who says that they feared Jun would be still alive. The stack of papers on the desk is more towards the center of the desk than it is in the rest of the scene. (00:08:05)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: When Kindaichi holds the army knife picking it up from the ground, it has two stripes of blood across the blade, just one stripe when Detective Li picks it up.
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: Lee's men are chasing Kindaichi that just escaped from the air conditioning vent. In one shot (the one with the camera behind the two guys) the policeman wearing the white shirt has the earpiece on the wrong ear - left ear, while he wears it on the right ear in the rest of the scene. (00:09:00)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: After Akechi's stabbing, Detective Li Pai-Long puts his hand on Kindaichi's shoulder, very close to the neck in the first shot, further towards the arm in the second. (00:03:20)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: Kindaichi drops the knife that falls at distance and rolls on the floor clear from obstacles, but it's at his feet in the wide shot. (00:02:50)
The Death March of Young Kindaichi File 1 - S2-E1
Continuity mistake: When Kindaichi is slapped offstage, his body turns one way in one shot, but he lands in the opposite way in the next. (00:13:25)
The Death March of Young Kindaichi File 1 - S2-E1
Continuity mistake: Inside the hotel room, the three guys from 18 years prior receive a macabre gift. The one in the grey suit opens the box, and the knuckles of the severed hand are pointed towards him. In the last shot of the table though, the hand is turned the other way around. (00:08:15)
The Death March of Young Kindaichi File 1 - S2-E1
Other mistake: During this episode and the next 4 of this story arc, the signs of the stores in Hong Kong are recycled from the first episode of the series. Hong Kong is a pretty big city, the odds of Kindaichi (who is not staying at the same hotel nor dealing with anything related to the first case) just happening to be in the same nondescript streets with the "Ocean Guest House" are astronomically low.
The Game Mansion Murder Case File 3 - S1-E25
Plot hole: An additional plot twist of the episode has the Puppeteer from the Hell as the mastermind behind the operation. What does not make sense is the fact that he regularly visited the killer in prison showing his face fully in the open. To make it even more ludicrous, the next episode shows that he needs to constantly wear a mask because he's wanted by the police, and he is on the run. Previous episodes showed already without a doubt that the police had all his data and pictures.
The Game Mansion Murder Case File 2 - S1-E24
Continuity mistake: The bottles of tea on the buffet table change position between shots as the Game Master introduces the trial. (00:04:50)
The Game Mansion Murder Case File 1 - S1-E23
Other mistake: When the guy who keeps crying tells Kindaichi the name of his mother, he regains his missing tooth just for a shot. (00:16:15)
The Game Mansion Murder Case File 1 - S1-E23
Continuity mistake: The tickets on the counter at the beginning of the episode are one on top of the other but change position between shots.
Inspector Kenmochi the Murderer File 2 - S1-E20
Continuity mistake: In the scene with Kindaichi and Miyuki talk to the old fiancé on the rooftop of the police station, the shadow cast by the building changes significantly from the beginning of the conversation to the end. (00:05:50 - 00:07:10)
Inspector Kenmochi the Murderer File 2 - S1-E20
Continuity mistake: During Reiji Aoi's flashback, the young fiancé is holding the phone with Marina's coerced text message in his right hand. Next shot and the hand is the left one. (00:06:15)
Inspector Kenmochi the Murderer File 2 - S1-E20
Continuity mistake: The forensics team member that drains the tub and performs a quick postmortem on the victim is wearing a facemask. However, in the close-up of the moment when he bags the phone as evidence, his chin is in frame and bare. (00:03:10)
Inspector Kenmochi the Murderer File 1 - S1-E19
Other mistake: The police is searching the crime scene of the supposed suicide. The police was alerted because the suicide happened by drowning, leaving the bathtub running till it overflew alerting the other people in the building. The body of the victim is still completely immersed in the bathtub (nobody drained it), and Kindaichi and Aoi walk on a dry floor while there should be a massive flooding.
Inspector Kenmochi the Murderer File 4 - S1-E22
Continuity mistake: The position of Kindaichi's phone when it falls inside the bathtub changes between shots. The tub itself also fills way too quickly - and Kindaichi is in no rush to retrieve it.
