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
Character mistake: For being a genius raised abroad, Takato's English pronunciation is abysmal - check out when he says the line about the magic crystal on stage. (00:12:40)
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
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 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 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: 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: Inside the laundry cart, Kindaichi asks Longtao where does he bring the linens. The cloth on top of his head slips behind him, but this happens again in the next shot; it's back on his head and drops all the way down again. (00:09:35)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: When Kindaichi falls from the cart, the boxes around him are placed in a way that it's not just incongruous continuity-wise from shot to shot, but is also nonsensical; in one shot for instance he has a box through each leg, but since Longtao smuggled him out inside them, both legs had to be inside the same box; the cardboard was surrounding him. (00:12:30)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: When Longtao carts away from the hotel the boxes, they are all the same texture, but when the wheel is caught in the step, the middle box is striped. (00:12:30)
The Death March of Young Kindaichi File 2 - S2-E2
Continuity mistake: Kindaichi searches Akechi's wallet with his right hand, using the left hand to hold the wallet itself, but hands Longtao the taxi receipt using the left hand. (00:13:05)
The Death March of Young Kindaichi File 2 - S2-E2
Other mistake: The two survivors from 18 years prior approach the building with nothing on their person, then suddenly Matsuoka has a flashlight, which he gives to Shinomiya as he goes inside alone. Kindaichi and Longtao arrive, completely unprepared to any dungeon crawling, and the three of them go in with yet another flashlight. (00:13:50)
The Death March of Young Kindaichi File 2 - S2-E2
Plot hole: It's unreasonable, nor is explained in the denouement at the end of this arc, how did the murderer, who stayed behind everyone else on purpose, get to Shinomiya who was ahead of everyone, went inside the cave before everyone else and didn't have a reason to hide, cooperate with him or anything of the sort.
The Death March of Young Kindaichi File 2 - S2-E2
Other mistake: When Kindaichi rushes to Longtao's rescue, he is not carrying the flashlight with him. He's in a deep cave bunker with no light at all (plot point mere moments earlier), he should be blind as a bat. In the following episode he even searches for clues in the cave, again without the light.
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 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 3 - S2-E3
Plot hole: The crowd freaks out when Matsuoka's body is found and Kindaichi happens to be standing in front of it, gun in hand. That's all sorts of silly though, not only because the killer could have never predicted that turn of events, but also because Kindaichi roamed the streets looking for Matsuoka, gun in hand the whole time (it's a different gun from the one Matsuoka is killed with), and it's a girl screaming that draws everyone's attention to the murder. What about the two gunshots? Everyone in the background was entirely unfazed. It also creates a separate issue in the ending, since the plan to frame Kindaichi was supposed to be 'perfect' but the different gun would have spoiled it. (00:08:35)
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: The pile of bread that Longtao brings for breakfast changes between shots. (00:11:10)
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)
