這場在2026年初引發日本漫畫界劇烈動盪的醜聞，源於小學館被揭發長期包庇曾違反《兒童色情禁止法》的性犯罪者，並協助其隱姓埋名重返創作領域。這起事件的核心人物為漫畫家山本章一（本名栗田和明），他過去曾任職高中教師，卻因性侵15歲女學生而遭到逮捕。令人震驚的是，小學館編輯部在明知其刑事案底的情況下，仍協助他以筆名「一路一」擔任作品《常人假面》的原作，甚至有編輯部成員涉嫌介入受害者的和解協商，試圖以此壓下負面消息，掩蓋真相。

隨著社會輿論爆發，小學館編輯部被迫於2月底發表正式道歉聲明，坦承內部處置嚴重不當，並即刻宣布暫停《常人假面》的連載及所有單行本的出貨計畫。然而，官方的遲來表態並未能平息憤怒，反而觸發日本漫畫界前所未有的集體抵制浪潮。

多位在業界舉足輕重的漫畫大師紛紛採取強硬立場，要求將作品撤出小學館旗下的數位平台「Manga ONE」。其中，傳奇作家高橋留美子率先開出第一槍，撤下《犬夜叉》、《亂馬 1/2》及《福星小子》等全數經典名作；當紅作品《葬送的芙莉蓮》的原作山田鐘人與畫師阿部司也主動要求下架以示抗議。此外，《映像研還有問題！》的作者大童澄瞳等多位創作者亦相繼加入，以此表達對出版商「保護加害者勝過守護人權」的強烈不滿。

目前，小學館正陷入創立以來最嚴峻的公關危機與誠信考驗。這場由創作者發起的「自淨運動」，不僅重創出版社的品牌形象，也迫使整個產業重新審視職業道德與社會責任的底線。

This scandal, which triggered a massive upheaval in the Japanese manga industry in early 2026, stems from allegations that Shogakukan systematically protected a sex offender previously convicted under the "Child Pornography Prohibition Act" and assisted him in making a professional comeback under a pseudonym.

At the heart of the controversy is the writer Shoichi Yamamoto (real name Kazuaki Kurita), a former high school teacher who was previously arrested for the sexual assault of a 15-year-old female student. Shogakukan's editorial department was reportedly fully aware of his criminal record yet chose to facilitate his return as the writer for the manga Joujin Kamen under the pen name "Ichi-ro-ichi." Disturbingly, reports suggest that editors even intervened in settlement negotiations with the victim in an attempt to suppress negative publicity and conceal the truth.

As public outcry intensified, Shogakukan's editorial department issued a formal apology in late February 2026, admitting to severe professional negligence and announcing the immediate suspension of Joujin Kamen's serialization and shipment. However, this response failed to quell the indignation of the creative community, sparking an unprecedented collective boycott by legendary manga artists.

High-profile creators have taken a stand by demanding their works be removed from Shogakukan’s digital platform, "Manga ONE." Iconic artist Rumiko Takahashi led the protest by pulling all her classic titles, including Inuyasha, Ranma 1/2, and Urusei Yatsura. Similarly, Kanehito Yamada and Tsukasa Abe, the creators of the hit series Frieren: Beyond Journey's End, requested the immediate withdrawal of their work. Other notable figures, such as Sumito Oowara of Keep Your Hands Off Eizouken!, have also joined the boycott.

Shogakukan is currently facing the most severe public relations crisis in its history. This movement, driven by creators, reflects a profound loss of trust, as readers and artists alike accuse the publisher of "prioritizing the protection of a perpetrator over human rights."
