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.

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.

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.
