“Bankaku Rock / Ranking Boss Rock” (番格ロック) Original release Japanese two-sheet billboard poster, 1973 — excellent unrestored condition (B0 Billboard approx. 103 × 146 cm / 40.5 × 57.3 in)
Offered here is an extraordinary large-format original Japanese theatrical billboard poster for Bankaku Rock (番格ロック), Toei’s 1973 sukeban / delinquent-girl action film directed by Makoto Naitō and starring Emiko Yamauchi as Otonashi Yukiko. Released during the peak years of Toei’s hard-edged female-led exploitation cinema, the film follows the violent rivalry between the Akabane 100 Club and the Ikebukuro Cavalry, with Yukiko newly released from reform school and drawn back into a one-woman reckoning with the rival gang.

Context
Toei’s sukeban world: delinquent girls, street codes, and violent hierarchy
The term “bankaku” is central to the film’s identity. It refers to a boss-class enforcer or bodyguard within a delinquent group: not merely a follower, but the gang’s active fighter and hard-line protector. In this film, Yukiko occupies that dangerous position — a lone-wolf figure defined by nerve, violence, loyalty, and personal code.
That idea is made visual with remarkable force on this poster. Yamauchi’s Yukiko dominates the left sheet in a full-length white outfit, open jacket, and knife in hand, placed against a blazing orange urban backdrop. The poster’s own copy reinforces her rank and reputation: with one call, a hundred sukeban gather, but Yukiko is 番格 — a boss-class figure whose courage and physical strength make her a feared presence in the street hierarchy.
Emiko Yamauchi
A brief but highly collectible Toei screen presence
Emiko Yamauchi occupies a distinct place in early-1970s Toei genre cinema. Her screen career from this period is compact but potent, including Neon Jellyfish (1973), Bankaku Rock (1973), Neon Jellyfish: Shinjuku Hanadensha (1973), and School of the Holy Beast (1974). In Bankaku Rock, she plays Otonashi Yukiko, the central figure around whom the poster’s entire visual impact is built.
On this billboard, Yamauchi is presented not as supporting decoration but as the whole selling proposition: cool, dangerous, controlled, and confrontational. Her white costume against the saturated orange cityscape gives the design its immediate power, while the knife and low-angle composition transform the image into a near-mythic sukeban portrait.
Carol
Rock’n’roll as marketing, soundtrack, and cultural signal
A major element of the poster is the blue star-shaped inset featuring Carol, the influential Japanese rock’n’roll band led by Eikichi Yazawa. Formed in 1972, Carol became closely associated with early-1970s Japanese youth culture through their leather-jacket image, pompadour styling, and direct rock’n’roll sound.
Their presence here is not incidental. The film heavily promoted Carol’s involvement, with the band appearing in the film and contributing music that gave the action an added rock rhythm and countercultural charge. The inset functions almost like a concert-poster element embedded inside a theatrical advertisement, making this piece especially desirable beyond film-poster collecting alone.
As a result, the poster sits at the intersection of Toei exploitation cinema, sukeban iconography, Japanese rock history, Carol, and Eikichi Yazawa.
The film this poster represents
Akabane vs. Ikebukuro: girl-gang warfare at full Toei intensity
The story centres on the war between the Akabane 100 Club and the Ikebukuro Cavalry. Yukiko, the bankaku of Akabane, returns from reform school with unfinished business: a violent grudge match against the rival gang and a wider street conflict that escalates through betrayal, male criminal interference, and revenge.
The film belongs to the same broad Toei world as the studio’s early-1970s female-led action and delinquent-girl cycles, but it remains less widely circulated internationally than the better-known Female Prisoner Scorpion, Girl Boss, and Terrifying Girls’ High School titles. That relative obscurity gives surviving original advertising material — especially in billboard format — particular collector weight.
The poster
One of the great graphic statements of Toei’s 1970s delinquent-girl cycle
This B0 two-sheet design is exceptionally strong, both as cinema advertising and as 1970s Japanese graphic art.
Key visual elements include:
The full-length Yamauchi image: a towering, low-angle presentation of Yukiko in white, knife forward, placed against an orange urban field of distorted architecture.
The title treatment: hot-pink, jagged, angular lettering for 番格ロック, visually echoing rock typography and the fractured violence of the film.
The Carol star inset: a deep blue star containing the band in performance, with “CAROL” rendered in yellow burst lettering — one of the poster’s most collectible music-related elements.
The girl-gang vignettes: smaller street-level images showing the gang formations and urban delinquent milieu that drive the plot.
The colour scheme: orange, black, pink, blue, and white — high contrast, loud, and unmistakably 1973 Toei.
At B0 scale, the composition becomes far more than a standard film poster. Yamauchi’s figure becomes almost life-size in effect, the title typography dominates the right sheet, and the Carol inset reads as a second cultural advertisement within the same object.
Rarity and survival
A scarce billboard-format Toei sukeban poster
Japanese B0 two-sheet posters were made for large-scale theatrical display rather than ordinary domestic collecting. They were more difficult to store, more vulnerable to handling, and far less likely to survive intact than standard-size posters. For a cult Toei title such as Bankaku Rock, a complete two-sheet B0 example with both panels present is a significant find.
Its appeal crosses several collecting categories: Japanese film posters, Toei pinky-violence and sukeban cinema, Emiko Yamauchi, Carol, Eikichi Yazawa, and early-1970s Japanese rock culture.
Condition
Excellent unrestored original presentation
This example presents in excellent unrestored condition, with vivid colour, strong printed detail, and the expected original fold structure from theatrical distribution. The photographs show light handling, fold lines, and minor creasing consistent with age and use, but the overall visual impression remains extremely strong. The reverse views show clean paper tone and the original sheet structure, further supporting the poster’s excellent presentation as a surviving theatrical display piece.
Condition
Very Good / Excellent. Please review the photos—they show the exact poster for sale.
Collector’s note
This is the kind of poster that defines a collection: a visually explosive B0 two-sheet for a rarely seen Toei sukeban title, anchored by Emiko Yamauchi’s commanding central image and elevated by the prominent presence of Carol at a key moment in Japanese rock history. For collectors of 1970s Japanese exploitation cinema, delinquent-girl films, and rock-linked movie advertising, Bankaku Rock is a major piece.
It is not a reproduction or a reprint.
Certificate of Authenticity included.
