Young Kidaichi's Murder: File 1 - S2-E1
Revealing mistake: There's a frame of animation obviously missing when the cameraman moves past the rest of the crowd that gathers after the maid's scream. He basically teleports past Miyuki while his hand is still in the same position it had when he had the hand on her shoulder. (00:14:40)
Ghost Passenger Ship Murder Case: File 1 - S2-E5
Continuity mistake: Despite being drunk, the captain is pretty good with prestidigitation, since both the bottle of booze and the letter disappear during after he showed them in his speech. (00:11:50)
Ghost Passenger Ship Murder Case: File 1 - S2-E5
Continuity mistake: At the dismal dinner party, Miyuki wears her hair in front of her right shoulder, except in the shot when the ocean magazine photographer introduces himself, when all of a sudden her hair is all the way back, and then after the captain throws his glance at the crowd in POV. (00:09:35)
Ghost Passenger Ship Murder Case: File 1 - S2-E5
Other mistake: In the initial flashback, the name of the ship ("Mary Celeste") is misspelled, appearing on the stern, is "Mary Celese." (00:02:05)
Young Kidaichi's Murder: File 1 - S2-E1
Continuity mistake: When Kindaichi leaves the table to go get a new cup of coffee, his strawberry yogurt has been opened and eaten with a spoon, but it was untouched just a few seconds before. (00:10:35)
Young Kidaichi's Murder: File 4 - S2-E4
Factual error: The bittersweet ending is powerful from a dramatic point of view, but also impossible, because law (in Japan, at least) explicitly forbids organs coming from suicide victims to go to their family members, to prevent behaviour exactly like the one displayed here.
Young Kidaichi's Murder: File 4 - S2-E4
Continuity mistake: When Itsuki retrieves the floppy disk and shows it to the other people in the room, in the first shot the fingertip is on the plastic edge, in the second it's by the metal shutter. The color is off, since a few parts that are plastic are colored like metal. (00:05:00)
Young Kidaichi's Murder: File 3 - S2-E3
Continuity mistake: The policeman's bandages join at the bottom in the first shot when they are visible (when he's behind the Nagano inspector), but join in the middle in the other shots. (00:09:40)
Young Kidaichi's Murder: File 3 - S2-E3
Continuity mistake: When Hajime is looking at the photo of the crime scene, the outline of the body is correct when it comes to the arms position, but the torso is straight, when it was very much bent in the first episode. (00:08:55)
Young Kidaichi's Murder: File 3 - S2-E3
Continuity mistake: Kindaichi uses his hands to free the policeman; his hands happen to be at different height in the reverse shot. (00:04:45)
Young Kidaichi's Murder: File 3 - S2-E3
Continuity mistake: Kindaichi's head peeks from the corner of the window at different levels when he spots the silly policeman getting stuck. (00:04:35)
Young Kidaichi's Murder: File 3 - S2-E3
Continuity mistake: Kindaichi is looking at the pictures he laid out on the train's floor. When we see the wide shot with all the pictures, they don't match any of the closer angle. (00:03:40)
Young Kidaichi's Murder: File 2 - S2-E2
Continuity mistake: Katsura gets stabbed in front of Kindaichi; Kindaichi's tie is missing part of the string as he calls Katsura's name the first time. (00:21:15)
Young Kidaichi's Murder: File 2 - S2-E2
Continuity mistake: The space between the steps of the metal staircase Kindaichi is (amazingly well) hiding changes between shots. In fact when the beeper beeps, the whole back of Kindaichi appears to be leaning on solid steel. (00:20:20)
Young Kidaichi's Murder: File 2 - S2-E2
Other mistake: Kindaichi is on the run from the police. He rolled in dirt with his only shirt and jeans, and he had multiple dirt stains when he was on the phone with Miyuki in Nagano, but at the end of his clandestine trip in the back of a truck, he shows up in Tokyo perfectly clean.
Young Kidaichi's Murder: File 2 - S2-E2
Continuity mistake: When Kindaichi pages Miyuki, she clicks the button on top to answer, but in the next shot she's holding the device in a different way. (00:04:15)
Young Kidaichi's Murder: File 1 - S2-E1
Other mistake: Kindaichi escapes handcuffing the detective to the toilet's chain. Try to think of the last time you went to a restroom and the chain was SO long that you could yank it across the whole room (not stall, room) and outside the door. Going behind the sink's drain, even. Never seen a toilet like this in my life (and in that kind of bathroom, you have usually buttons or pedals, anyway). (00:21:00)
Young Kidaichi's Murder: File 1 - S2-E1
Other mistake: Miyuki notices the pager beeping and finds out that Kindaichi gave it to her without her noticing. In fact when he said goodbye to her, the keen-eyed viewer can actually spot him slipping her the device. There are a couple of slight problems with that; first, she retrieves it, not in frame, from her left side, but Kindaichi put it on the right side of her person. Second; she is wearing a white skirt with no pockets. (00:20:15)
Young Kidaichi's Murder: File 1 - S2-E1
Continuity mistake: When Aoi repeats the question to the old servant, she has her hand on the lady's shoulder in the first shot, suddenly not in the second. (00:17:55)
Young Kidaichi's Murder: File 1 - S2-E1
Continuity mistake: Reviewing Saki's footage of the evening of the murder, the part that shows Natsume is taken from an angle much closer than what it should be; Saki was sitting at the other end of the couch, not directly to her left. (00:17:00)
