Evil Spirit of the Diving Pool - S1-E18
Other mistake: Kindaichi is watching poolside the athletes on day two. He is sitting cross-legged, but his right foot is drawn wrong and the toe is twisted in an impossible position. (00:08:10)
Evil Spirit of the Diving Pool - S1-E18
Continuity mistake: In the scene with two swimmers having a physical altercation, the bag of 'the ripper' is in a different spot on the bench between shots. (00:05:30)
Evil Spirit of the Diving Pool - S1-E18
Continuity mistake: At the beginning of the flashback from three years prior, Miyuki pounds the top of Hajime's head with a righteous fist. At the cut, he has his left hand up, while in the first shot it was lowered. (00:03:15)
The Campground 'Bizarre' Case - S1-E17
Continuity mistake: When Kindaichi tries to escape and Miyuki stops him in his tracks exposing the reason why he's leaving, the cup in front of her is positioned with the handle facing right. When we see the cup again, it faces the opposite direction. (00:21:20)
The Campground 'Bizarre' Case - S1-E17
Deliberate mistake: The evidence that proves Kindaichi's alibi is the store receipt detailing the time of his purchase. Notice that the year is recorded too, but it reads "20XY." (00:12:40)
The Campground 'Bizarre' Case - S1-E17
Continuity mistake: When Miyuki discovers the larceny perpetrated at her expense, proportion and position of the folded clothes change between shots. (00:10:45)
Murder at 10,000 Meters File 2 - S1-E16
Continuity mistake: Throughout the episode, number and position of the airplane windows vary. You don't have to freeze-frame and count them; a cursory look at the door at the center of the plane is enough. The way the windows by it are grouped together changes in number and the door is sometimes at the end of the line, sometimes in the middle of it.
Murder at 10,000 Meters File 1 - S1-E15
Continuity mistake: The captain's cap is on a different spot on top of the control panel when the investigators first see his body.
Murder at 10,000 Meters File 1 - S1-E15
Other mistake: In several instances throughout the episodes, the seats in the corridors appear empty even if the plane is supposed to be at full capacity.
Murder at 10,000 Meters File 1 - S1-E15
Other mistake: On the plane, Akechi is reading, according to the dialogue, an "English newspaper." The newspaper is called "Global Times", but it's not supposed to be the real life one, which is a Chinese newspaper (albeit with an english edition); the logo is different. However, for being a Western-style newspaper (which is what Kindaichi calls Akechi out for), its front page is positioned wrong, like a Japanese newspaper.
The Prison Prep School Murder Case File 5 - S1-E14
Continuity mistake: When the mastermind does his dramatic escape, the policemen are in front of him (Kenmochi literally at arm's length), but there's nobody in his way when he throws his projectile. (00:18:15)
The Prison Prep School Murder Case File 4 - S1-E13
Other mistake: Kindaichi puts on the table the map of the two buildings. The one to the right has a cutout part, but still shows as a full sheet. (00:19:00)
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: The burn marks on Adechi's tracksuit change throughout the episode. For instance, look at his left forearm; sometimes it has a dark spot, some other times it does not. (00:16:00 - 00:17:15)
The Prison Prep School Murder Case File 3 - S1-E12
Plot hole: Kujiragi's textbook is missing. It's a plot point and it's something the culprit did to plant an evidence using a page from it. However, when the case is solved, this point is glossed over; only a page from the book was needed, which the culprit could have ripped away at any moment without stealing the book, and more importantly, when Kindaichi finds the book, there was no window of opportunity for the killer to put it back; Kindaichi and Kujiragi were right there in the corridor the whole time. The live version adaptation fixes this hole because the character finds his book only the day after, in class.
The Prison Prep School Murder Case File 3 - S1-E12
Continuity mistake: Kujiragi grabs Kindaichi asking about his textbook; Kindaichi raises both hands almost putting them in the aggressor's face, but at the cut you get an unobstructed view of him; Kindaichi's arms are lowered. (00:05:00)
The Prison Prep School Murder Case File 2 - S1-E11
Character mistake: When we first see Kindaich in English glass, the blackboard behind the masked teacher shows the word "grammar" misspelled into "grammer." (00:12:10)
The Prison Prep School Murder Case File 2 - S1-E11
Continuity mistake: In the opening shot of the 'briefing' about the camp's structure, Kendaichi's backpack is twice the size it turns out to be in the rest of the scene. (00:03:20)
The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: Once the Puppeteer disappears, you can't see Miyuki's glass and the box on the table any more either (but she has another table behind her when you see her hand in the foreground). (00:21:30)
The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: After the Puppeteer's speech, the box emits sparks. Adechi shields his face with his sleeve fully in close-up, while in the wider angle he is mouth agape with the arm positioned at a lower angle. (00:20:50)
The Prison Prep School Murder Case File 1 - S1-E10
Continuity mistake: When Adechi sits down with the others, the handle of Kenmochi's cup of coffee faces Adechi in the first shot, Kenmochi in the next. (00:19:15)
