Cerebral sleuth Qin Feng (Liu Haoran) and his larger than life uncle Tang Ren (Wang Baoqiang) are back on the case in the third instalment in the Detective Chinatown franchise (唐人街探案3, Tángrénjiē tàn àn 3) picking up as promised in Tokyo as the duo take on another locked room mystery on the invitation of dandyish local investigator Hiroshi Noda (Satoshi Tsumabuki). This time around, the mystery is only tangentially connected to a Chinatown though the solution in itself does indeed lead back towards the Mainland and the complicated relations between China and Japan, while Qin in particular finds himself confronting the idea that oligarchy is in fact the “perfect crime”.
Hired by a yakuza boss, Watanabe (Tomokazu Miura), accused of offing a Thai rival, Su Chaiwit, following a dispute over development rights in the local Chinatown, Qin and Tang Ren quickly find themselves hamstrung by their own discovery of evidence which further implicates their client and brings them to the attention of top cop Tanaka (Tadanobu Asano) who wastes no time telling them to mind their own business. Meanwhile they are also being pursued by muscly Thai detective Jaa (Tony Jaa) working for the other side. In a new high tech motif, the guys are each handed a simultaneous translation earbud which allows the Japanese and Chinese guys to converse with each other in their own languages though Hiroshi often chooses to speak directly in Mandarin instead while the Thai contingent exclusively use English. Unlike previous instalments the duo do not venture into the local Chinese community and Chinatown itself is merely territory contested by Japanese yakuza and South East Asian gangsters.
Even so Qin and Tang Ren find themselves at a nexus of cross-cultural conflict caught between the cops, yakuza, and Thai gangsters each looking not so much for the truth but some kind of advantage for their side all of which culminates in a hilarious series of mixups at a morgue. Once again, Tang Ren falls in love with a local woman, in this case Su Chaiwit’s secretary Anna Kobayashi (Masami Nagasawa) who is certain Watanabe is guilty and later apparently kidnapped by a crazed serial killer (Shota Sometani) just by coincidence. Of course, all this cycles back towards the franchise’s growing mythology, Qin pursued and manipulated by the mysterious entity known only as “Q” which, as we learn, is as obsessed with the idea of the perfect crime as Qin largely in that they think they’ve perfected it in the stranglehold placed over civilisation by a shady elite.
In this, the film may be taking aim at hidden oligarchy and the immorality of growing social inequality, but in its Japanese setting Chen is also freer to take potshots at contemporary Chinese society such as in Tang Ren’s confusion that they can’t simply bribe the police to get Qin out of jail when he is wrongfully arrested. “Justice and equality require sacrifices” Qin explains after solving a grim riddle only to be asked some difficult questions about the nature of justice and his own role within it by a manipulative villain, but in a classically censor-friendly move ends the movie with a brief monologue declaring that “justice always prevails and light overcomes darkness”, he and his team recommitting themselves to fighting “vices”, and presumably the shady elitism fostered by Q, wherever they arise.
Like Detective Chinatown 2’s New York setting, the vision of Japan on display is deliberately stereotypical from an Akihabara cosplay carnival to tasks involving masked kendo fighters and a sumo wrestler, not to mention bumbling comedy yakuza forever threatening to cut off their fingers, the Shibuya Scramble set piece, or a playful homage to Phoenix Wright: Ace Attorney. Meanwhile, Chen continues his taste for huge ensemble action such as the complex slapstick routine that opens the film and now traditional end credits sequence featuring the cast dancing to theme tune “Welcome to Tokyo” dressed in the classic green detective mac worn by Qin. Truth be told, the solution to the central mystery is heavily signposted and slightly unsatisfying though Chen’s visualisations of Qin’s deductions are expertly rendered even as the hero’s growing confidence as a crimefighter unbalances his relationship with the increasingly silly if goodhearted Tang Ren. Boasting a host of A-list Japanese acting talent, the film also makes space for an unexpected cameo from one of the most recognisable faces in Sinophone cinema before teasing a further instalment to take place in London, home to the greatest consulting detective of them all.
