Japan's Quirk & Health Department

Established by Diet degree in 2051, the Japanese Quirk Registry is a semi-confidential, government controlled, centralized database of Japan's Quirks and Quirkers. When a child’s Quirk first manifests, it is recorded and named by their doctor, and logged into the database. Most family doctors will allow some input from the child’s family, and potentially, the child themself, on the name of the quirk. As the Quirker matures, their quirk is generally further assessed within safe reason by their doctors, and further information is recorded into the database. Upon reaching the age of 16, all citizens are issued a government identification card, which also serves as their driver’s license. For Quirkers, this also bears the name of their Quirk, and type within the four-type system (Summon, Mutation, Emitter, Transformation).

A citizen’s quirk information is generally treated as a matter of medical confidentiality, and is not accessible to the general public. However, in addition to being recorded on their medical file, all quirk information is recorded in a government database managed by the Japanese Quirk Department, a subdivision of the Ministry of Health--publicly, part of the census. Police have the power to pull a quirker’s information from this data with a warrant, or during exceptional circumstances (during a crime involving the person). Other government agencies can also request access to this data for a variety of reasons.


The simplest way to avoid appearing on the Registry is never be entered in the first place. Criminal families, such as the Yakuza, have long-employed loyal private doctors who are well-payed for their silence. This means "family quirks" are often hidden from the government. Doctors who fail to report a quirk face being stripped of their medical license, fines, and even imprisonment, but only if they are caught.

Even if someone's quirk is in the database, frequent use of a false identity can confuse or fragment their "quirk file," or prevent them from being connected back to their true self. Of course, fake IDs come in various qualities, from "barely good enough to get into a bar" to "fool the police."

Finally, it's possible to modify or erase someone's quirk file...but this is by far the hardest route. Doing so would require hacking a government database, bribing a government official, or bribing a doctor to enter false data.


Pro Heroes, Sidekicks and UA Students Quirk information becomes classified when they gain their position, meaning it takes a significantly higher level of government clearance to access them. The PSC takes over their Quirk Registry, and approves a select group of trusted medical workers to file data on their quirk. This means it would take significantly greater effort to pull a student or pro's file. On the other hand, Heroes and heroes-in-training are practically celebrities, so general details of their quirks tend to be common knowledge.


The Japanese Quirk Registry has been a heated source of debate and controversy since its inception. Since its creation, it often been considered an invasion of privacy, and a possible prelude to discrimination, or even, as some alarmists claim, eugenics. However, others argue that its too private, and people have the right to know if they’re in the presence of dangerous quirks. They also argue that some children have been known to hide the extent of their Quirks, and more extensive and intrusive testing of Quirks is necessary. Some prefectures have mandated special symbols on ID cards to indicate the especially uncontrollable or destructive quirks, or established sub-databases to allow public citizens to look up more detailed quirk information than name and type.

In addition, many insurance companies, schools, landlords, and employers will request information to quirk records before entering a contract. This, of course, has been battled in court as discriminatory, but thus far, has neither been outlawed, or fully legally approved--it rests in limbo.

Finally, there exist numerous private quirk databases run by organizations, especially anti-quirk groups such as The One People's East Asian Group, and Anti-Quirk Group of Mustafa. These are especially controversial, and often cross the line into illegal harassment.
