Shogakukan Faces Major Human Rights Fallout After Third-Party Probe Into Manga ONE

Shogakukan has stepped into a messy storm. The publisher released the findings of a third-party investigation into its Manga ONE editorial department, and the verdict was blunt: in the case involving manga creator Shōichi Yamamoto, the company "encouraged and supported" the violation of the victim's human rights. That is not a light tap on the wrist. That is the kind of line that lands like a dropped frying pan in a quiet kitchen.

On the following day, the company also unveiled a set of countermeasures. The goal is simple on paper and difficult in practice: rebuild trust, tighten governance, and stop editorial convenience from bulldozing over human rights. We know the script. The problem is usually not writing the policy. The problem is living it.

What the investigation found

According to the summary, the external committee received reports of 44 incidents through dedicated hotlines during the investigation. The reports covered suspected sexual misconduct, abuse of authority, and other forms of misconduct. Some involved senior executives. Others involved employees using their position like a sledgehammer. There were also cases of editors behaving badly toward creators, which is a bad look for a field that depends on trust, timing, and a fair amount of caffeine.

The committee said the company responded properly in some instances, but not in others. In plain terms, the brakes worked sometimes and failed at other moments. That is not enough when human dignity is on the line.

The report also pointed out a structural failure. Editorial decisions were prioritized even when human rights violations were suspected. Coordination between editorial, legal, administrative, and management departments did not function well enough. In the victim's case linked to Yamamoto, the committee said the company went beyond passive failure and helped create the conditions for the violation.

That is the sharpest part of the report. It suggests not just negligence, but a system that leaned in the wrong direction. A publishing house should not become a maze with no exit sign.

Salary cuts and public accountability

Shogakukan said its executive team will take salary cuts for three months. The president will cut his salary by 50%. Other board members, directors, and auditors will reduce theirs by 20% to 30%. It is a symbolic move, but symbols matter when public confidence is wobbling.

We have seen this kind of response before. It is a classic corporate raincoat: useful for the optics, less useful if the storm keeps pouring through the roof. Still, it shows the company knows the damage is real.

Five measures meant to close the gaps

Shogakukan says it will turn the report's recommendations into concrete action. The reforms touch corporate culture, human rights training, reporting systems, and relations with external creators. The company says it wants a fundamental reset. That is a big phrase. Now comes the boring part, which is often the most important part.

Human rights policy and a new committee

The company drafted the Shogakukan Human Rights Policy on March 19. It says the publisher intends to respect and protect fundamental human rights across its activities. Shogakukan will also create a Human Rights Committee, led by senior managing director Kumiko Hanazuka and including outside experts. Its role will be to prevent, reduce, and correct violations.

Training and a culture shift

Regular training will be expanded. The sessions will cover respect for human rights, prevention of sexual violence and harassment, victim support, and whistleblowing procedures. Managers will get separate instruction on supervision and guidance. The company will also prepare guidelines for dealing with outside partners and offer human rights seminars to writers, authors, and freelancers.

That matters. In publishing, relationships are the engine. If the engine overheats, everybody feels it. A company cannot act like a quiet editor's room is automatically a moral compass.

Clearer rules for working with external creators

Shogakukan will review its human rights policy with external creators and add related clauses to contracts. If concerns arise, the company says it will use a clearer reporting and decision-making structure involving editorial, legal, and administrative departments. Those teams will decide whether a business relationship should continue.

That is the kind of process that should already exist. But better late than never, as the saying goes. Even in Murcia, where we know that waiting too long for rain can make everyone suspicious of the sky.

Stronger oversight

The Board of Directors will receive regular reports on human rights violations. When incidents surface, the company will check whether similar problems exist in other divisions. Human rights decisions will pass through the Risk Management Office, the Human Rights Committee, and the Legal Department before management confirms the results. Depending on the severity, special response committees or emergency response committees may also be created.

This is the corporate equivalent of adding more locks after a door has already been left open. Necessary? Yes. Elegant? Not really. Effective? That will depend on follow-through.

Better whistleblowing and complaint systems

The company will set up a grievance mechanism aligned with the UN Guiding Principles on Business and Human Rights. It will allow complaints even from victims who do not have a direct contract with Shogakukan. Anonymous reporting will be possible, and protections after reporting will be strengthened. For sexual assault cases, the company says it will provide a specialized response system, including psychological counseling for victims.

That part should be standard, not exceptional. A reporting system that frightens people into silence is not a system. It is a decorative box.

Why this scandal hit so hard

The current crisis did not appear out of nowhere. It sits on top of earlier controversy involving Yamamoto. In February, the Sapporo District Court ordered a man to pay 11 million yen in damages to a woman in her 20s who said he repeatedly sexually abused and raped her while she was a student and he was a teacher. Later reports identified that man as Shōichi Yamamoto, the creator of Daten Sakusen.

There was also a separate criminal case in 2020, in which Yamamoto was convicted of violating the Child Prostitution and Pornography Prohibition Act and fined 300,000 yen. Those figures are not just legal footnotes. They explain why any editorial involvement around his work became radioactive.

Shogakukan also admitted that during settlement negotiations in the civil case, a manga editor took part and advised that a lawyer should prepare notarized documents. Other reports said the editor suggested adding a condition preventing the woman from disclosing the matter, and proposed a settlement payment of 1.5 million yen. That is the kind of detail that can make even seasoned readers blink twice.

The wider fallout for Manga ONE

After the initial statements from Manga ONE and Shogakukan, several manga creators criticized the publisher publicly. Some said they would remove their titles from the platform. That kind of backlash is not just noise. In manga publishing, creators are the bloodstream. If they start looking for another hospital, management notices very quickly.

Shogakukan then postponed the award ceremony for the 71st Shogakukan Manga Awards, which had been scheduled for March 3. The timing was not ideal. It had all the grace of a chair missing one leg.

Another scandal already weakened trust

The company was already under pressure from a separate internal review tied to the act-age writer Tatsuya Matsuki, who used the pen name Miki Yatsunami for Seisō no Shinri-shi on Manga ONE. Matsuki had been arrested and indicted in 2020 for a coerced indecent act involving a female middle school student.

Shogakukan said the pen name had originally been chosen to avoid re-victimizing those involved. But the company later admitted its editorial team should have thought more carefully about whether that choice truly served the victims' interests. That is a recurring theme here: intent is not enough when the outcome still hurts people.

Our view? If a publisher wants to be trusted, it must act like trust is part of the business model, not a decorative accessory. The audience can forgive a lot of things. What it does not forgive easily is a company appearing to treat human rights like an annoying sub-plot.

Shogakukan says it will keep reviewing its measures and later publish the full list in English. That is the next checkpoint. The real test will not be the statement. It will be whether the company can turn policy into muscle memory.

We will keep watching this one closely. If the reforms work, they could become a useful blueprint for the industry. If they do not, this will just be another thick file on a very crowded desk.
