This is the first time I actually caught a Detective Conan film on opening day. And I of course know Conan, especially the films, are huge, but when I arrived at the theater, they had seven films scheduled in the coming hour, and six of them were Detective Conan, with a new screening starting every ten minutes, which is insane.
Part 1: Volumes 1 ~ 10
Part 2: Volumes 11~20; The Timebombed Skyscraper (1) / The Fourteenth Target (2)
Part 3: Volumes 21~30; The Last Wizard of the Century (3) / Captured in Her Eyes (4)
Part 4: Volumes 31~40; Countdown to Heaven (5) / The Phantom of Baker Street (6)
Part 5: Volumes 41~50; Crossroad in the Ancient Capital (7) / Magician of the Silver Sky (8) / Strategy Above the Depths (9)
Part 6: Volumes 51~60; Private Eyes' Requiem (10) / Jolly Roger in the Deep Azure (11)
Part 7: Volumes 61~70; Full Score of Fear (12) / The Raven Chaser (13) / Lost Ship in the Sky (14)
Part 8: Volumes 71~80; Quarter of Silence (15) / The Eleventh Striker (16) / Private Eye in the Distant Sea (17)
(You will find the links to the reviews of volumes 70, 72~76, 78, 82~105 and the films Quarter of Silence (15), The Eleventh Striker (16), Private Eye in the Distant Sea (17), Dimensional Sniper (18), Sunflowers of Inferno (19), The Darkest Nightmare (20), The Crimson Love Letter (21), Zero the Enforcer (22), The Fist of Blue Sapphire (23), The Scarlet Bullet (24), Bride of Halloween (25) and The Black Iron Submarine (26) and The Million-Dollar Pentagram (27) in the library or via the Detective Conan tag)
The "sleeping detective" Mouri Kogorou receives a phone call from Sametani Kouji, a former co-worker who unlike Kogorou is still with the Metropolitan Police Force. He is investigating a shooting incident in the mountains that occured ten months ago involving Inspector Yamato of the Nagano Prefectural Police, and because Wani learned Kogorou has worked with him on a few cases in the past, he wants to ask Kogorou a few questions. The two are to meet in Hibiya Park the day after tomorrow, but when Kogorou, daughter Ran and Conan (the high-school detective turned into a child) arrive in the park, they are witness to Sametani being shot by a hooded assailant. While Conan gives chase on this turbo-powered skateboard, the assailant manages to escape in the hustle and bustle of the city. The Metropolitan Police Department suspect it was Sametani's investigation into the Nagano case that led to the attack, so Inspectors Satou and Takagi are sent to Nagano Prefecture, with Kogorou inviting himself to the team. The Tokyo inspectors meet with their Nagano colleagues Inspector Yamato, Uehara and "Koumei", and learn about the case ten months ago: Inspector Yamato had been chasing a convicted criminal on the run deep in the mountains of Nagano, near the Nobeyama Radio Observatory, when a third party suddenly shot at him. A terrible avalanche followed immediately, which swept Yamato away. While a search was initiated, they could not find the inspector, and he was initially assumed missing in action, but some time later, it was discovered Yamato had survived the avalanche and had been recovering in a local clinic. He had however lost the use of one eye after being shot, and he had also lost his memories initially, though he eventually recovered most of his memories and is now working again full-time as a police detective. Yamato however has no precise memories of who or what he saw the second before he was shot and the avalanche occured. However, if Sametani was shot because he was investigating this case, it seems likely Inspector Yamato himself too will become a target too because he is an actual eye-witness and involved party. Can they find out who the mysterious attacker is sealed within Inspector Yamato's memories before it's too late in the 2025 theatrical release Detective Conan: One-eyed Flashback?
Detective Conan: One-eyed Flashback is the 28th film in the long-running Detective Conan series originally created by Aoyama Goushou, with Sakurai Takeharu, a veteran in the animated adaptation of the series, once again responsible for the script. He was previously responsible for Private Eye in the Distant Sea, Sunflowers of Inferno, The Darkest Nightmare, Zero the Enforcer, The Scarlet Bullet and The Black Iron Submarine, and One-eyed Flashback shares a lot with especially the last four titles on the list: these films feature stories that build a lot on storylines and character arcs of the main series, and if you are not up-to-date with those storylines, you might feel left behind because these films are not really accessible without the proper prior knowledge (though they are generally fun as action films anyway). This is especially the case for One-eyed Flashback, where a large part of the story revolves around an untold episode from the main series: when we first met Inspector Yamato in the Fuurin Kazan case in volume 59, we heard bits and pieces about his backstory: he had been missing for some time after a certain incident in which he lost the use of his eye (hence the cross-shaped scar across his left eye) and had only recently recovered and returned to his work as a detective. In subsequent stories, we'd learn about his Chinese proverb-spouting rival/friend Morofushi Takaaki aka "Koumei" (Kongming) and how he'd been involved in finding Yamato, but exact details about what caused Yamato's disappearance, and how he lost his eye, were never given in the original manga. So to get the most out of this film, you ideally want to have seen/read the previous stories involving the Nagano Prefectural Police. If you are invested in the Nagano Prefectural Police trio, I do really recommend watching this film, as it clears a lot up regarding Yamato's background. While the events in the film-series of Conan are not "canon" per se for the manga (buildings don't blow up every week in the manga), series creator Aoyama Goushou does always provide the basic ideas for each film, and offers "stories he can't tell in the manga medium" to the film production committees, and ever since the first film, characters and pieces of backstory told in the films are considered as "canon" for the manga.
And also watch this film if you're a Kogorou fan. It's been a while since he's been featured so prominently in the films (certainly not fter his original voice actor Kamiya Akira had been replaced by Koyama Rikiya starting Lost Ship in the Sky). Though to be honest, due to certain scenes in the film I really wished Kamiya Akira was still in this role... And regarding another voice change: while I had already heard Kusao Takeshi as the new voice of Amuro in the television anime series a few weeks ago, he had more "significant" scenes in this film as someone who helped Conan keep up to date with the police investigation, and I got used to him pretty quickly.
As a mystery film though, One-eyed Flashback is very simple, presenting itself as a police procedural. We realize very quickly that the assailant is trying to keep something that happened in the Nagano mountains ten months ago a secret, and that they are willing to go very far to keep it a secret, even targeting active police detectives. Meanwhile, the Tokyo detectives, in cooperation with their Nagano and Yamanashi Prefectural Police colleagues and Kogorou, hope to get a clue regarding the assailant's true identity by investigating the incident that occured ten months ago: Yamato had been chasing after a convicted armed robber, who had previous robbed a hunting rifle store with a conspirator. Ultimate this case is very simple in structure with few characters involved, and that leaves also little room for the current case to become interesting mystery-wise, as the accent lies on "somebody's shooting at these police detectives!!". The few attempts at misdirection are feeble, though I do really like the most direct hint pointing at this film's culprit: a very simple one, but it was implemented very competently. And I wonder whether something they did in regards to the culprit was a coincidence or not, but that was pretty funny too as a meta-clue in hindsight. Funnily enough, I can almost imagine this as one of those longer lore-based stories we see in the Conan manga lately, where the core mystery plot is just a vehicle to allow Aoyama to develop the underlying storylines/characters, as the last few years, these stories have featured simpler and simpler mystery plots. With the plot being less bombastic than previous film, the main story of One-eyed Flashback feels more like it could have been in the manga, if you ignore the ridiculous action scenes. So don't be watching One-eyed Flashback for the mystery, as it's nothing special. When scriptwriter Sakurai pulls out his old "political thriller" card (something he uses a lot in his Conan films), the story does become a lot more interesting to be honest, as he gives a certain character a fantastic scene in the post-credits, but the political angle not really deeply connected with the mystery save for informing us of the culprit's motive.
A large part of the film is also set at the Nobeyama Radio Observatory by the way (as it's near where the avalanche happened ten months ago), which is not only a place Dr. Agasa and the Detective Boys visit in the film... I happened to have visited it myself too earlier this year. After the initial trailer of One-eyed Flashback was revealed last year, it became clear the Nobeyama Radio Observatory, and its 45-m radio telescope would be featured heavily in the film, so I visited it in January when I was nearby, figuring I should probably have a look at it because there was a non-zero chance it would get blown up in the film considering that's generally what happens in Conan films with structures with an iconic look! Picture above was taken by me by the way! It was cool to have seen the real place first, and then reproduced in the film again, as it was really the exact same place and layout... well, except for how it's depicted in the climax of the film, but that's artistic licence for you...
While I did enjoy my time in the theater a lot, I do have to say Detective Conan: One-eyed Flashback is probably best seen if you have done your homework first, and don't come here for mainly the mystery. It is a story that feels like it could have been a "somewhat drama/moviefied" adaptation of a manga episode with a somewhat subdued police procedural as its main framework to tell a story that had gone untold in the manga until now, focusing on Kogorou (who wants to know why his friend was shot) and Inspectors Yamato, Koumei and Uehara of the Nagano Prefectural Police, whose lives are still obscured by the shadow of the avalance ten months ago. So very much recommended for those who liked cases like Fuurin Kazan from the main series. The film ended, as per tradition, with a teaser for the 2026 film. Not super excited because it appears we'll have another character-focused film again and I am not particularly a great fan of this character, so not sure where the story will go, but whatever it'll be, I'll be sure to watch it!
