If you study Japanese, you will sooner or later read a procedural mystery novel such as the one this film was adapted from, because their narrative is matter-of-fact observation, and the mystery evolves through a sequence of events - perfect to learn the language. Many movies have been based on these but are largely unknown in the West, because these films do not conform to our expectations of police procedural drama.
The violence is toned down, but comes as an element of shock nevertheless, because the film takes a long time to establish its protagonists - a skill Uchida had honed in a career of almost 50 years. While few of his prewar social dramas survive, and most of his postwar samurai epics are glaringly violent and experimental, this three-hour epic completely focuses on characterization, which has a strong immersive effect. The story is hardly noteworthy, which seems to irritate a few reviewers and won't work with everyone. But it's hard not to be enthralled by Sachiko Hidari's pure hearted yet masochistic prostitute, and Rentarô Mikuni's brooding fugitive meandering between innocence and brutality. Comedian Junzaburô Ban completes the trio of leads difficult to forget as the ill investigator haunted by an unsolved case. It also features a rather young Ken Takakura just before his break to stardom with "Abashiri Prison" as a novice cop.
What makes the three hours worth sitting through and makes this Uchida's undisputed masterpiece is the ending. It is not entirely unexpected but the way it is executed is truly unforgettable. Definitely required viewing for those interested in the Japanese psyche and slow, careful character establishment.
