In the manga-magazine corner of a bookshop, a magazine whose cover character looks out in a swimsuit sits on the shelf. Boys’, youth, and women’s magazines mix together, and the cover art alone makes them hard to tell apart. Pick one up and turn the pages, and between the main story a fan-service scene lays bare the heroine’s chest, yet within a range that does not depict the genitals directly. This is the subject of this article. Erotic content in youth manga is the general term for sexually suggestive work carried in the non-adult shonen and seinen manga magazines handled in the general bookshop distribution system. Distinguished from “adult magazines,” it has tried out expression that arouses without depicting genitals or intercourse, a distinct field of postwar Japanese manga.

The premise of the distinction

Japanese manga magazines are divided in distribution by the presence or absence of an adult mark (the eighteen-plus mark and shrink-wrap). This article treats the erotic expression in shonen and seinen magazines without an adult mark, whose distribution and regulation differ from eromanga and adult magazines. The basic territory of youth-manga eros is the range that excludes direct genital and intercourse depiction but performs sexual appeal through swimsuits, underwear, undressing, close contact, kisses, and fan-service shots. The distinction is held by a complex of mechanisms: the self-regulation of the publishing-ethics council, bookshop handling categories, and magazine codes. Work carried in shonen or seinen magazines may shift in regulatory range when reissued as doujinshi or as a collected volume, and expression is sometimes revised between magazine serialisation and volume collection.

Dawning: Nagai Go’s Harenchi Gakuen

The work that first widely established the genre consciousness of youth-manga eros is often given as Nagai Go’s Harenchi Gakuen (Weekly Shonen Jump, 1968-1972). Set in a school, it depicted skirt-flipping between teachers and pupils, nudes of schoolgirls, bathing scenes, and toilet motifs, drawing strong criticism from parents’ groups, PTAs, and educators while winning the overwhelming support of the child audience and becoming a social phenomenon. Its significance lay in bringing into the shonen-magazine frame the devices of sexual appeal previously confined to the adult arena. The skirt-flipping, nude, and bathing depictions were presented within a range that did not depict the genitals directly yet kept their provocative charge. This method of “depicting by not depicting,” of showing through omission, became the basic grammar of later youth-manga eros.

Development in the 1970s

After Harenchi Gakuen, the erotic expression of shonen and seinen magazines was gradually systematised. On the shonen side, Magazine, Sunday, and Jump increased works incorporating swimsuit scenes and fan-service elements, and the ecchi of gag manga and the female-nude depiction of drama manga settled in parallel. On the seinen side, Young Comic (1967), Big Comic (1968), Young Jump (1979), Young Magazine (1980), Young Sunday (1982), and Morning (1982) formed a market for an older intermediate readership. In these magazines, nude and swimsuit gravure covers, opening colour gravure, and serials with strong fan-service elements were regularly set, and the genre consciousness of youth-manga eros took hold.

The 1980s: ecchi romantic comedy

In the 1980s, shonen magazines acquired the genre of romantic comedy. Takahashi Rumiko’s Urusei Yatsura (Weekly Shonen Sunday, 1978-1987) and Katsura Masakazu’s Video Girl Ai (Weekly Shonen Jump, 1989-1992) placed the heroine at the centre of sexual appeal while the main line read as a love comedy, a double structure. The readership centred on adolescent males, and the match between the magazine’s main buyers and the works’ erotic elements brought commercial success. The period fixed the sexual-appeal devices into a set of types: the “swimsuit chapter,” the “hot-spring chapter,” the “bath scene,” and the “accidental underwear glimpse,” conventions repeated thereafter and fixed as the grammar of youth-manga eros.

The 1990s to 2000s

From the 1990s, the upper limit of sexual depiction in seinen magazines expanded in stages: the exposure of cover nude gravure, the stimulation of opening swimsuit gravure, and the concreteness of undressing depiction within works all gradually rose amid inter-magazine competition. The shonen side, mindful of the age of its readership, readjusted to restrain excessive depiction, widening the expressive distance between shonen and seinen magazines. In the late 2000s, Yabuki Kentaro and Hasemi Saki’s To Love-Ru (Weekly Shonen Jump, 2006-2009, with the sequel To Love-Ru Darkness from 2010 to 2017) drew note as a work that updated the upper limit of sexual depiction possible within the shonen frame, combining accident-type ecchi, alien-heroine nudity, and elements of bathing, tentacles, and restraint within the shonen editorial standard.

Limits and significance of the expression

Youth-manga eros has accumulated its own rhetoric to solve the task of performing sexual appeal while not being adult-rated: the concealment of genitals by light, steam, cloth, or objects, suggestion through the cropping of the frame, supplementation by sound effects, the concentration of emotional information through close-ups of the face, and the typing of fan-service shots, all procedures for “depicting without depicting.” In cultural history, youth-manga eros has functioned as a cognitive device of “sexuality within daily life.” Unlike explicit eromanga, it sits on the general bookshelf and is read in a state where family eyes may fall on it. This placement naturally regulates the upper limit of sexual depiction, and as a result it has been a medium that socially negotiates the range of “moderate sexual appeal.” Within the layered structure of the Japanese manga market, shonen magazine, seinen magazine, eromanga, and doujinshi, youth-manga eros carries an important wing of the intermediate layer.
