The Hong Kong Kowloon Treasure Murder Case File 1 - S1-E1
Other mistake: Throughout the episode, certain street signs ("Job&Piece", "Ocean Guest House") are used multiple times in different points of Hong Kong (for instance the establishing shot of the city, behind Kindaichi and his friends when they meet, during the bike chase).
The Hong Kong Kowloon Treasure Murder Case File 2 - S1-E2
Other mistake: Miyuki calls Kindaichi at 9:48 AM. Hearing the pink dolphin hint, they run to the Kowloon Palace statue. When at that location Saki shows him the picture, the cell phone says it's 15:24. Too much time elapsed between the two moments. (00:17:00)
The Hong Kong Kowloon Treasure Murder Case File 2 - S1-E2
Other mistake: When Saki shows the picture of Ran's butt, the photo is taken from the right of the girl. In the scene during the previous episode, Saki was standing on Hajime's left, and he could never take that shot from that angle.
The Hong Kong Kowloon Treasure Murder Case File 3 - S1-E3
Other mistake: Saki was filming the table from his seat, and he couldn't have got close-ups of the soup bowls from the angle proposed. (00:04:45)
The Prison Prep School Murder Case File 3 - S1-E12
Other mistake: During the science lesson about DNA, the teacher shows the double helix structure. One wonders how could he draw it using 3 colors since he has just white chalk at his disposal. The figure disappears a moment later when he starts giving out the test papers. (00:06:30)
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)
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.
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
Other mistake: In this episode, we learn that Kindaichi can't swim. However, the series is a continuation of the first one from 1997: in a few instances (the Ghost Passenger Ship Murder Case, The Kidnapping of Reika Hayami Murder Case, with Reika appearing as a key character here) Kindaichi could swim just fine and in fact would bravely dive in the ocean to save someone and swim downstream in a mountain river when gravely injured, respectively.
Inspector Kenmochi the Murderer File 1 - S1-E19
Other mistake: There's a coloring mistake in the glass in front of Busujima in the shot when finishes playing his handheld game and sends the waitress away; the glass is half empty / half full...but vertically. The part to the right of the straw is full to the brim and the part to its left is nearly empty. (00:10:35)
Inspector Kenmochi the Murderer File 1 - S1-E19
Other mistake: Hajime ends the conversation with Miyuki, but the screen on her phone still shows the conversation going. (00:13:50)
Inspector Kenmochi the Murderer File 1 - S1-E19
Other mistake: When Akechi drives Kindaichi to the scene of the shooting, the tachometer of his car is set at 0. (00:14:00)
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
Other mistake: When Kindaichi shows his phone with the incriminating evidence, the phone's charge is at 60%, exactly the same charge it had last time we saw the same phone screenshot for the same purpose in the previous episode. Mere minutes later for the bathtub demonstration Miyuki calls him and the phone is charged at 80%. (00:07:50)
Inspector Kenmochi the Murderer File 4 - S1-E22
Other mistake: When Busujima tells the real story of what happened 3 years before, the bathtub in the background drained completely, but nobody removed the drain stopper, which in fact is in frame and perfectly placed. (00:10:55)
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)
