ADDITION: Masters of Cinema 4K UHD (September 2026): Masters of Cinema have transferred Teruo Ishii's Bohachi Bushido: Code of the Forgotten Eight to 4K UHD and Blu-ray. I expected the Masters of Cinema 4K UHD of Bohachi Bushido: Code of the Forgotten Eight to look the same as the Mondo Macabro 4K UHD reviewed below. It is starkly different. Masters of Cinema describe theirs as "from a 4K digital restoration" but don't name the source, while the Mondo used a brand-new 4K scan of the original camera negative. Both have HDR, but the color grades go in opposite directions. The Masters of Cinema is warm, with a golden-amber cast across the whole frame. Skin tones are ruddy and tanned, lips are a strong orange-red, and the wood paneling of the Yoshiwara interiors glows yellow. The Mondo Macabro is cooler and more neutral, with a slight magenta lean. Faces look pale, almost porcelain, lips are a muted peach, and the shoji screens sit in a neutral blue-grey. It isn't only the actors' makeup: the walls and backgrounds shift by the same amount, so this is a different color grade across the whole image. The MoC also has more contrast, with deeper, richer black levels and brighter highlights, while the Mondo is flatter, with raised blacks and softer peaks. Grain is heavier and more pronounced on the Masters of Cinema, giving it a more textured, film-like appearance, and the Mondo's medium-bodied grain looks finer and quieter by comparison. Framing is effectively the same on both, at about 2.39:1. The Masters of Cinema is on a triple-layered disc, and its feature's video bitrate is about 30% higher than the Mondo's, which was already a strong encode. Neither label says which grade is closer to the 1973 Toei theatrical look. To my eye, the MoC's saturated palette suits Juhei Suzuki's garish reds and fever-dream lighting better, while the Mondo's cooler grade favors the bluish/lavender hallucinatory sequences of the later acts but drains the warmth elsewhere. Our comparison captures below show the MoC's richer color.

Bohachi Bushido: The Villain is a different story. It's on the second disc, a Blu-ray it shares with a 1080p presentation of Code of the Forgotten Eight. It has not been restored, and the print shows plenty of speckles throughout. Our captures look a shade softer, and the modest bitrate is only about 9% higher than Discotek's 2023 single-layered US Blu-ray (not reviewed.) It's watchable, but it isn't in the same league as the 4K UHD of Ishii's film.

It is likely that the monitor you are seeing this review is not an HDR-compatible display (High Dynamic Range) or Dolby Vision, where each pixel can be assigned with a wider and notably granular range of color and light. Our capture software if simulating the HDR (in a uniform manner) for standard monitors. This should make it easier for us to review more 4K UHD titles in the future and give you a decent idea of its attributes on your system. So our captures may not support the exact same colors (coolness of skin tones, brighter or darker hues etc.) as the 4K system at your home. But the framing, detail, grain texture support etc. are, generally, not effected by this simulation representation.

NOTE: We have added 50 more large resolution Blu-ray captures of Bohachi Bushido: The Villain (in lossless PNG format) for DVDBeaver Patrons HERE

For the audio, Masters of Cinema use a linear DTS-HD Master 1.0 channel mono track (24-bit) in the original Japanese language. The Mondo Macabro used a DTS-HD Master 2.0 channel track (16-bit), essentially dual-mono. The MoC's true single channel and greater bit depth make it the more faithful presentation of the original mono. Realistically, though, the difference is subtle, and I doubt many will hear a meaningful improvement. Hajime Kaburagi's eclectic score still stands out: traditional shamisen, koto and taiko drums fused with jazzy electric guitar and funky brass. Its dissonant strings and percussive intensity drive the action sequences, and the sword clashes and ambient brothel noises are crisp and authentic. Dialogue is clean and well-balanced, with no audible hiss or distortion. Masters of Cinema offer optional English subtitles, newly revised for this release, on their Region FREE 4K UHD. The Blu-ray disc is Region "B"-locked.

The Masters of Cinema carries over almost all of the Mondo Macabro supplements. Tom Mes's audio commentary analyzes the film's place amid the decline of 1960s studio cinema and Ishii's subversive take on jidaigeki conventions. The more conversational archive commentary in Japanese, with filmmakers J-Taro Sugisaki and Takao Nakano, is full of behind-the-scenes anecdotes. There's also the 17-minute interview with director Shinya Tsukamoto (Tetsuo: The Iron Man) on working with Ishii, and the 21-minute archive interview with Yuriko Hishimi. The 1/4 hour "What is Pinky Violence?" is still an excellent primer, and the theatrical trailer is included too. The only Mondo extra missing is the 42-second "Introducing the Commentators." New to the Masters of Cinema is Joe Hickinbottom's video essay, "From Codes to Chaos." It runs almost 1/2 hour and places both Bohachi Bushido films in the context of Toei's changing production strategies in the 1970s. There are also stills galleries for both films. These extras are on both discs. The big addition is the second disc Blu-ray with Takashi Harada's Bohachi Bushido: The Villain (1974). It's a spiritual successor rather than a direct sequel, released less than a year after Ishii's film, with a new cast and a new ronin: Goro Ibuki as the condemned criminal Kyushi Issho, who falls in with the Bohachi clan and becomes their protector and recruiter in the flesh trade. Harada lacks Ishii's psychedelic flair, and The Villain is less stylized and less hallucinatory, but it piles on the blood-spattered swordplay and builds to a brutal, drugged third act that mirrors the original's finale. Kaburagi returns for the score, and Shigeru Akatsuka handles the photography. The film features Reiko Ike as Monkumatsu, the fiery head brothel recruiter who packs a pistol and isn't afraid to use it. Ike was Toei's ultimate bad girl of the early '70s, often compared to Pam Grier and Tura Satana. She rose to fame in the Hot Springs Geisha series and went on to star in five of Toei's seven Sukeban (girl boss) films and all four Terrifying Girls' High School entries, including Women's Violent Classroom and Lynch Law Classroom. Other roles include Girl Boss Guerilla, Kinji Fukasaku's Graveyard of Honor, Norifumi Suzuki's Sex & Fury, Teruo Ishii's Female Yakuza Tale and Criminal Woman: Killing Melody. Discotek Media released The Villain on a barebones Blu-ray in the US in 2023 HERE, so the Masters of Cinema, with a new commentary by genre cinema expert Arne Venema and film writer Stefan Hammond, is its first UK home video release and the first with supplements. The limited edition of 2,000 copies adds an O-card slipcase with new artwork by Poochamin and a collector's booklet with new writing on the Bohachi Bushido films by Jennifer Coates, author of Film Viewing in Postwar Japan, 1945–1968.

The Masters of Cinema 4K UHD of Bohachi Bushido: Code of the Forgotten Eight is not the same transfer as the Mondo Macabro, and to my eyes it's the superior one. It's warmer, richer grade, deeper black levels, more pronounced grain and roughly 30% higher bitrate give Ishii's lurid ero guro jidaigeki more punch, and our captures show the fuller color. The true 1.0 channel 24-bit mono is a modest technical step up. The supplements match the Mondo almost exactly, and Masters of Cinema add Joe Hickinbottom's video essay, galleries and a second film. That film, Bohachi Bushido: The Villain, is a far cruder efforgt by comparison. Its extended scenes of female torture push well past the stylized excess of Ishii's original into something far uglier, and even with Reiko Ike's hypnotic presence it's hard to recommend on its own merits. Its unrestored, speckled, greenish and slightly soft Blu-ray appearance doesn't help. It's best treated as a curiosity for completists. The reason to buy this set is the 4K UHD of Code of the Forgotten Eight, my favorite of this genre, and that made the double-dip an easy decision for me. Mondo owners who love Ishii's film should seriously consider it, and for newcomers the Masters of Cinema two-disc set is the edition to own. Certainly recommended to lovers of the genre!

ADDITION: Mondo Macabro 4K UHD (April 2026): Mondo Macabro have transferred Teruo Ishii's Bohachi Bushido: Code of the Forgotten Eight to 4K UHD. We reviewed the 2025 Mondo Macabro Blu-ray release HERE.

NOTE: This is a standalone single 4K UHD disc edition with no second disc Blu-ray, slipcase of booklet like Mondo Macabro's 2025 4K UHD package that sold out quite quickly. 

This uses the same brand-new 4K scan from the original camera negative as the earlier limited combo pack. The 2160P image quality is solid and filmic overall, with intact medium-bodied grain that keeps the 1973 exploitation look authentic rather than overly polished. Close-ups deliver decent texture on faces, skin, and costumes, while the HDR grading brings noticeable improvements in the film's stylized sequences - particularly reds of blood and the eclectic cool bluish / lavender lighting in the later acts - giving those hallucinatory, drug-fueled moments more depth and separation than the 2025 Blu-ray.

That said, the presentation isn't super tight across the board. Black levels are stable without major crush, and there's no obvious noise reduction or compression issues, but the film was never a technical showcase to begin with, so the upgrade feels more like a refined version of the Blu-ray than a transformative one.

It is likely that the monitor you are seeing this review is not an HDR-compatible display (High Dynamic Range) or Dolby Vision, where each pixel can be assigned with a wider and notably granular range of color and light. Our capture software if simulating the HDR (in a uniform manner) for standard monitors. This should make it easier for us to review more 4K UHD titles in the future and give you a decent idea of its attributes on your system. So our captures may not support the exact same colors (coolness of skin tones, brighter or darker hues etc.) as the 4K system at your home. But the framing, detail, grain texture support etc. are, generally, not effected by this simulation representation.

On their 4K UHD, - like the Blu-ray - Mondo Macabro also use a DTS-HD Master 2.0 channel track (16-bit) in the original Japanese language. Sound effects (such as sword clashes and ambient brothel noises) give an air of authenticity. Hajime Kaburagi’s (Eighteen Years in Prison, By a Man's Face Shall You Know Him, The Executioner, Horrors of Malformed Men, The Sleeping Beast With, Retaliation, Blind Woman's Curse, Fairy in a Cage, Tokyo Drifter) eclectic score (a fusion of traditional Japanese shamisen, koto, and taiko drums with jazzy electric guitar riffs and funky brass) is the standout, rendered with impressive clarity and depth. The score’s dissonant strings and percussive intensity shine during action sequences, while plaintive melodies underscore Shino’s existential despair, preserving the film’s nihilistic tone. Dialogue in the original Japanese is crisp and well-balanced with no audible hiss or distortion. The lossless audio transfer of Bohachi Bushido: Code of the Forgotten Eight sounds solid and the minimal depth suits the film. Mondo Macabro offers optional English subtitles on their Region FREE 4K UHD.

On the 4K UHD Mondo Macabro duplicate their own Blu-ray supplements that provide extensive context for Bohachi Bushido’s place in Japanese cinema, catering to both casual fans and scholars of exploitation genres. The new audio commentary by Japanese film expert Tom Mes (Japanese Film and the Challenge of Video) is informative, offering an in-depth analysis of the film’s historical backdrop, including the decline of 1960s Japanese studio cinema, the rise of pink films, and Teruo Ishii’s subversive take on jidaigeki conventions. Mes delves into the film’s ero guro roots and its critique of Edo-era corruption. The archive audio commentary in Japanese with optional English subtitles (see sample below) featuring filmmakers J-Taro Sugisaku and Takao Nakano is more conversational, providing behind-the-scenes anecdotes about Ishii’s chaotic directing style and the film’s production challenges, complemented by a brief “Introducing the Commentators” featurette that outlines their credentials. The 17-minute interview with director Shinya Tsukamoto (Tetsuo: The Iron Man) is a gem, exploring Ishii’s influence on his own work and offering insights into the anarchic energy of 1970s genre cinema, though it focuses more on Ishii’s broader oeuvre than Bohachi Bushido specifically. The 20-minute archive interview with lovely actress Yuriko Hishimi (Godzilla vs. Gigan,) who played a minor role, provides a personal perspective on working with Ishii and navigating the film’s explicit content, enriched by her reflections on the pinky violence era. The 1/4-hour “What is Pinky Violence?” interview is an excellent primer, tracing the genre’s origins, its blend of sex and violence, and its cultural significance with clips from related Toei films, like Female Yakuza Tale. The theatrical trailer retains the film's lurid charm.

As noted this does not have the 24-page booklet, featuring an essay by Mark Schilling (No Borders, No Limits: Nikkatsu Action Cinema) on the ero guro and Toei Porno subgenres, adds scholarly depth.

Teruo Ishii's Bohachi Bushido: Code of the Forgotten Eight is a striking example of Japanese exploitation cinema, blending the samurai chanbara genre with ero guro (erotic grotesque) aesthetics. The film has relentless violence, pervasive nudity, and philosophical undercurrents, making it a complex, if polarizing, work that transcends its exploitation roots to offer a critique of power, humanity, and the commodification of desire. At its core, Bohachi Bushido is a meditation on nihilism and the rejection of humanity’s moral frameworks. The Bohachi clan’s name, derived from the Chinese term for “forgetting the eight virtues,” encapsulates their ethos: a deliberate abandonment of conscience, loyalty, and shame to pursue power and pleasure. Teruo Ishii’s (Orgies of Edo, Horrors Of Malformed Men, Inferno of Torture) directorial vision elevates Bohachi Bushido beyond mere exploitation. Juhei Suzuki’s (Terrifying Girls' High School: Lynch Law Classroom) cinematography is a standout, employing vibrant colors, psychedelic lighting, and dynamic compositions to create a fever-dream aesthetic. The opening sequence (set against a blood-red sunset) sets the tone with its operatic violence, while interior scenes in Yoshiwara’s brothels use garish reds and greens to evoke decadence. I don't think I have ever seen so many topless Japanese females. The display extends to the majority of frames in Bohachi Bushido. The Mondo Macabro 4K UHD release of Bohachi Bushido: Code of the Forgotten Eight is a triumph for fans of Japanese exploitation cinema. If you already own the Mondo Macabro Blu-ray, reviewed HERE, that came out last year (which was derived from the same 4K master), there's little reason to double-dip on this lone 4K UHD disc - it's the same core transfer with HDR benefits that are nice but not essential for this kind of raw, groovy pinky violence title. The extras are carried over identically (minus the booklet), making the 4K mainly worthwhile for those who don't own the title yet and who want the highest-resolution option available. It's a keeper for me - because this is my favorite of this genre. Bohachi Bushido: Code of the Forgotten Eight stands out even within the wild world of 1970s Japanese pinky violence and ero-guro jidaigeki as the film that delivers the most abundant nudity and features one of the most beautiful casts of women in the entire genre. Director Teruo Ishii fills the screen with a near-constant parade of naked bodies - from the prostitutes under the Bohachi clan's protection to the deadly female ninjas and bodyguards who fight completely nude in one of the movie's most outrageous sequences. There are some impressive production values and I'm in love with Yuriko Hishimi who is one of the most prominent and memorable actresses in the cast among the Bohachi women / prostitutes. I expect this 4K UHD will sell out quickly as well.
