The Sea is Watching initially presents itself as a visually appealing movie; it boasts vibrant colors, skillful camerawork, pleasing compositions, and attractive actresses portraying sex workers. However, it then shifts into melodramatic territory, progressing to absurdity, ultimately ending with predictable elements that elicited a smile from me before the dreamlike sequences began. Throughout, though, the film consistently maintains its visual appeal. The narrative doesn't offer anything particularly original or innovative. It’s a pleasant, occasionally humorous, and melancholic story centered on the residents of a brothel during the samurai period whose entire neighborhood is submerged underwater. The plot primarily follows the romantic lives of two women who work there: Kikuno (played by Misa Shimizu), who acts as a mentor to the younger women and enjoys being desired without ever committing to anyone, and Oshin (Nagiko Tono), who seems to develop affections for each of her clients. One client, a kind samurai, frequently visits her and persuades her that even someone considered impure can be cleansed—just as hair, nails, and teeth naturally shed and regrow. "A body can become pure again ... it would be too horrible if it weren't true." Oshin is intended to serve as the film’s emotional anchor, experiencing heartbreak and longing, but this doesn’t fully materialize. While Shimizu and Tono deliver commendable performances, the acting in general isn't a strong aspect of the movie. I suggest this film to those interested in experiencing historical Japanese culture and who appreciate understated films about love, grief, and camaraderie. The women are portrayed as sex workers, certainly, but they possess emotions too.
