Japan's Research Misconduct Rules

Japan governs research misconduct through a national guideline issued by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), not through a single standing federal office comparable to the US Office of Research Integrity. Institutions carry the primary investigative responsibility, MEXT sets the rules they must follow and can withhold funding if they don’t, and the Japan Society for the Promotion of Science (JSPS) — better known internationally as a funding agency for KAKENHI grants and postdoctoral fellowships — also administers program-specific misconduct rules and mandatory research-ethics education for the researchers it funds. This guide covers how the framework is actually structured, what counts as misconduct under it, how institutions are required to respond, and where mandatory Responsible Conduct of Research (RCR) education fits in.

This is a companion piece to CASRAI’s coverage of other national research-integrity systems: the US Office of Research Integrity (ORI), the Netherlands’ LOWI second-opinion process, France’s OFIS, and Germany’s OWID/DFG system. Japan’s model shares the institution-led investigation pattern common to several of these but is distinctive in splitting misconduct oversight into two separate guideline tracks and in tying RCR education directly to funding eligibility.

Two guidelines, two tracks: research misconduct vs. misuse of funds

Japan’s national framework is not a single document. MEXT maintains two parallel guidelines that are easy to conflate but govern different problems:

Guidelines for Responding to Misconduct in Research — first issued in 2006 as Japan’s first national guideline on the subject, then substantially revised and re-adopted on August 26, 2014. This is the document that defines research misconduct itself and sets out how institutions must investigate and respond to it.
A separate guideline governing the proper management and audit of competitive research funds, which addresses misuse or misappropriation of grant money — padding invoices, fictitious purchases, diverting funds to unauthorized uses — as a distinct compliance problem from data fabrication or plagiarism, even though the same institutional integrity office often handles both in practice.

JSPS itself administers program-level rules that mirror this same split for the funding it distributes directly — its own regulations are explicitly titled to cover both “misconduct” and “misuse of funds” as separate categories within JSPS-funded programs.

What counts as “specific research misconduct” under the MEXT guidelines

The 2014 guidelines define specific research misconduct narrowly: fabrication, falsification, or plagiarism (FFP) of data or research findings in proposing, performing, or reporting research — committed either intentionally or through gross negligence of the basic duty of care expected of a researcher. This FFP framing is substantively similar to the definition used by the US ORI and by most national frameworks internationally, though the exact scope of what counts as gross negligence, and how it’s proven, is a matter for the investigating institution to apply case by case. The guidelines define the three categories as follows:

Fabrication — creating data or research results that do not exist.
Falsification — manipulating research materials, equipment, or processes, or altering data or results, so that the record no longer reflects what actually occurred.
Plagiarism — appropriating another researcher’s ideas, analysis methods, data, results, or wording without appropriate attribution or permission.

Conduct that falls outside this formal FFP definition — authorship disputes, duplicate publication, undisclosed conflicts of interest — is generally handled under separate institutional research-ethics policy rather than under the specific-misconduct investigation procedure the guidelines prescribe.

Institutional obligations: internal rules, reporting, and confidentiality

The guidelines place the investigative burden on universities and research institutions, not on MEXT directly. Institutions receiving MEXT or MEXT-affiliated competitive funding are required to:

Establish and publicly disclose their own internal rules for responding to misconduct allegations, consistent with the national guidelines.
Designate the specific offices and individuals responsible for receiving allegations, running preliminary review, and conducting formal investigations.
Protect the confidentiality of everyone involved — the person raising a concern, the respondent, and witnesses — throughout the process.
Report to MEXT when a specific-misconduct investigation is opened and again when it concludes.

An institution that fails to establish adequate internal rules, or that fails to investigate and respond appropriately once misconduct is alleged, risks a direct funding consequence: MEXT can reduce or suspend the institution’s competitive research budget, which gives the guideline real enforcement weight even though MEXT itself doesn’t run the investigations.

How an investigation proceeds

Once an allegation is received, an institution’s response under the guidelines generally moves through a sequence that secondary analysis of the framework summarizes as five phases: discovery of the allegation, formation of an investigation committee, compilation of the committee’s findings, disposition of the respondent researcher (sanctions where misconduct is confirmed), and, where the respondent contests the outcome, an appeal or litigation stage.

A structural requirement worth noting for anyone comparing Japan’s process to other national frameworks: the guidelines require that outside experts make up at least half the membership of the investigation committee, not just an advisory minority. This external-majority requirement is a stronger independence guarantee, on paper, than several peer frameworks that only require some outside representation. The exact number of business or calendar days allotted to preliminary review versus formal investigation is set within each institution’s own implementing rules rather than fixed uniformly by the national guideline itself, so specific timelines vary by institution — a researcher or administrator should consult the responding institution’s own published misconduct-response rules rather than assume a single national deadline applies.

Mandatory RCR education

The MEXT guidelines don’t just define misconduct and how to investigate it — they also require host institutions to build prevention into the front end, through mandatory Responsible Conduct of Research (RCR) education. Institutions are required to establish RCR education courses for researchers and to designate a responsible RCR education officer at the institutional level. In practice, this obligation is most visibly enforced through competitive-funding eligibility: researchers applying for or receiving JSPS-administered competitive funds, including KAKENHI grants, are expected to complete RCR training as a condition tied to that funding.

JSPS itself provides two of the principal RCR education resources used to satisfy this requirement:

“For the Sound Development of Science – The Attitude of a Conscientious Scientist” — a textbook available in both PDF and printed form, used as core RCR reading material across Japanese institutions.
e-Learning Course on Research Ethics (eL CoRE) — JSPS’s online RCR training platform, designed specifically for graduate students and widely used to satisfy the funding-linked training requirement.

This mirrors, in structure though not in specific mechanics, the funder-linked RCR training mandates CASRAI already covers for other jurisdictions — see our overview of Responsible Conduct of Research (RCR) training requirements and how completion tracking works, and the related RCR training dictionary entry, for how NIH and NSF structure comparable requirements in the US.

JSPS’s role, and how it differs from JSPS the funder

It’s worth being explicit about a distinction that’s easy to miss: JSPS’s funding-overview content on this site covers KAKENHI Grants-in-Aid and postdoctoral fellowships — JSPS as a grantmaking body. This guide covers a separate function JSPS performs: administering its own program-level rules for responding to misconduct and fund misuse within JSPS-funded research, and delivering RCR education content used across the wider MEXT-governed system. The two functions sit within the same organization but serve different purposes for a researcher or administrator working with JSPS — one is about how to apply for and manage a KAKENHI award, the other is about integrity obligations that attach once that funding is received. The Japan Science and Technology Agency (JST), a separate MEXT-affiliated body covered in CASRAI’s JST funding overview, also plays a role here: it operates Japan’s national Research Integrity Portal, which aggregates and links to the MEXT guidelines, institutional case reports, and related policy documents in one place.

How Japan’s framework compares internationally

Japan’s model sits closer to the institution-led investigation pattern used in the Netherlands and Germany than to a US-style scenario where a standing federal office (ORI) can itself review findings and issue federal sanctions:

United States — the Office of Research Integrity oversees PHS-funded institutions’ misconduct findings and can independently impose federal-level sanctions; see CASRAI’s broader guide on how a research misconduct investigation actually works in the US system.
Netherlands — institutions investigate first, with LOWI available as a national second-opinion body a dissatisfied party can escalate to.
France — OFIS, the French Office for Research Integrity, plays a coordinating and advisory role across institutions without itself running individual investigations.
Germany — the OWID/DFG Code of Conduct system relies on institutional ombudspersons and DFG-level guidance rather than a central investigating authority.
Japan — MEXT sets the national guideline and can withhold funding from non-compliant institutions, but individual investigations, including the requirement for a majority-external investigation committee, are run entirely at the institutional level, with no standing national body positioned to independently re-review a finding the way ORI or LOWI can.

For readers working across multiple jurisdictions, the practical takeaway is that “who actually investigates” and “who can override an institutional finding” vary meaningfully even among frameworks that use a near-identical FFP definition — Japan’s guidelines define misconduct in essentially the same terms as the US and EU frameworks, but the escalation path if a party disputes an institutional finding looks different from all four comparison systems above.

Frequently asked questions

Is JSPS Japan’s equivalent of the US Office of Research Integrity?

Not directly. JSPS is primarily a funding agency, and its misconduct-related rules apply specifically to JSPS-administered programs. The national misconduct guideline itself is issued by MEXT, and enforcement runs through funding leverage over institutions rather than through a standing investigative office comparable to ORI.

What is “specific research misconduct” under the MEXT guidelines?

It’s the guidelines’ defined term for fabrication, falsification, or plagiarism (FFP) of data or research results in proposing, performing, or reporting research, done intentionally or through gross negligence of a researcher’s basic duty of care.

Is RCR training legally mandatory for all researchers in Japan?

The MEXT guidelines require institutions to establish RCR education and designate a responsible officer, and completion is in practice tied to eligibility for JSPS-administered competitive funding such as KAKENHI — so it functions as a mandatory condition of funding for the large population of researchers who hold or apply for that funding, even though it is not framed as a universal individual legal obligation independent of funding status.

What’s the difference between the misconduct guidelines and the research-funds guideline?

The Guidelines for Responding to Misconduct in Research cover FFP in the research record itself. A separate MEXT guideline governs the management and audit of competitive research funds and addresses misuse of grant money as a distinct compliance issue, even though many institutions route both types of allegations through the same integrity office.

Can MEXT independently overturn an institution’s misconduct finding?

No. Investigations are run at the institutional level; MEXT’s leverage is that institutions must report findings to it and that MEXT can reduce or suspend competitive funding if an institution fails to establish adequate rules or fails to investigate properly — not a power to independently re-adjudicate a specific case.
