Japan's Civil Court Digitalization Goes Live May 21, 2026: The mints Mandate and the 7% Pro-Se Era

About 11 min read

On May 21, 2026, Japan's amended Code of Civil Procedure takes full effect. Online filing of complaints, electronic inspection of court records, and web-conference participation form the three pillars of the reform, and attorneys must use mints — the electronic submission system developed by the Supreme Court — to file documents. Press coverage has converged on a tone of "convenience" and "improved access to justice." But the structure looks different up close. The share of cases in which both parties appear pro-se in district-court civil litigation has fallen from roughly 20% to 7% over a decade, while approximately 90% of plaintiffs retain counsel. The population that benefits least from digitalization is already structurally a minority — and digitalization will likely accelerate that trend. Meanwhile, "latent unfiled cases," in which would-be plaintiffs abandon litigation because they cannot afford an attorney, remain invisible in judicial statistics. This article begins from the May 21 implementation date and unpacks the design of the three pillars, the international context, and how the constitutional "right to trial" (Article 32) is being reconstructed — solving physical access barriers while creating digital ones.

TL;DR

  1. On May 21, 2026, the amended Code of Civil Procedure takes full effect, simultaneously activating three pillars — e-Filing (electronic submission of pleadings), e-Case Management (electronic inspection of court records), and e-Court (web conferencing for hearings). Attorneys must submit through mints, the Supreme Court-developed system; pro-se litigants retain a paper-filing option, but practice will shift rapidly toward digital
  2. The share of cases in which both parties appear pro-se in district-court ordinary civil litigation has fallen from approximately 20% to 7% over a decade. Plaintiffs are represented by counsel in roughly 90% of cases. The population least able to benefit from digitalization is already structurally a minority — and digitalization will likely accelerate that decline. Meanwhile, "latent unfiled cases" in which would-be plaintiffs abandon litigation because they cannot afford counsel remain invisible in judicial statistics
  3. Singapore introduced full electronic litigation in 2000; the United States rolled out CM/ECF beginning in 2002; Germany completed its transition in the 2010s; Korea digitalized civil litigation in 2011. Japan's May 2026 full implementation is among the latest in the OECD. The Japan Federation of Bar Associations issued in September 2019 a basic policy for pro-se support during digitalization, proposing a three-tier framework (ICT support / procedural support / legal advice), but on-the-ground rollout of court terminals and pro-se support windows still varies by region

What Is Happening

May 21, 2026: full effect. e-Filing/e-Case/e-Court three pillars; attorneys must use mints

On May 21, 2026, the amended Code of Civil Procedure takes full effect. The amendment passed in May 2022, together with the related-laws integration act enacted in June 2023 (the "Integration Act"), comprehensively digitalizes civil-procedure practice. This is the inflection point.

Press coverage has converged on a single tone. The Nikkei headline reads "Online complaints and record inspection," and The Japan Times emphasizes "fully digital." Convenience, efficiency, expanded foreign-party participation — the affirmative framing dominates.

This article begins from the May 21 implementation and lays out the numbers that press coverage largely passes over. Specifically: the statistical fact that pro-se litigation has been falling sharply over the past decade, and the structural question of how digitalization interacts with that decline.

The Three Pillars of Reform

Civil-procedure digitalization is organized around three pillars.

Three Pillars of Civil Procedure Digitalization
Effective May 21, 2026 ─ mints mandatory for attorneys, paper option retained for pro-se
e-Filing
Electronic Filing
Online submission of complaints, briefs, and evidence via mints, the Supreme Court's electronic submission system
Attorneys: mandatory / Pro-se: optional
e-Case
Electronic Records
Digital court records. Parties and interested persons may inspect records from their own devices; third parties via court terminals
All cases
e-Court
Web Hearings
Oral arguments and conferences may be conducted via web conference. Witness examinations only where the court deems appropriate and neither party objects
Court discretion
Pro-se litigants retain a paper-filing option, but day-to-day practice will shift rapidly toward digital

Three pillars of Japan's civil-procedure digitalization fully effective May 21, 2026 (e-Filing/e-Case Management/e-Court) and the asymmetric mandate between attorneys and pro-se litigants

The first pillar, e-Filing, enables electronic submission of complaints, briefs, and evidence. The submission path is mints, developed and operated by the Supreme Court. As the Tokyo Bar Association LIBRA, March 2026 issue makes clear, attorneys (litigation representatives) must submit via mints. Pro-se litigants retain a paper-filing option, but practice will shift rapidly toward digital.

The second pillar, e-Case Management, digitalizes court records. Parties and interested persons can inspect records from their own devices around the clock; third parties (members of the public who wish to inspect) do so via court terminals. The round-trip and waiting time previously required for record copying at the courthouse counter are eliminated.

The third pillar, e-Court, allows oral arguments and case-conferences to be conducted via web conference. Witness examinations may also use web conferences, subject to the limitation that "the court deems it appropriate and neither party objects." For witness testimony, in-person remains the default. Oral arguments and case-conferences, on the other hand, substantially reduce the travel burden for remote attorneys and parties.

The Staged Rollout

It is not the case that "digitalization happens suddenly on May 21, 2026." The amendment has been rolled out in stages, and May 21 is the completion point. According to the Supreme Court, web-conference hearings began in March 2023 and have expanded since, while electronic service and some online filing functionality went live in 2024. May 21, 2026 consolidates these and definitively switches the regime from paper-based to electronic-based procedure.

In short, May 21 is not "the day change begins" but "the day change is complete." Legal professionals and the courts have been preparing in stages for years; for pro-se litigants and the general public, however, this will in most cases be the first encounter.

Background & Context

2019 JFBA policy → 2022 → 2026. OECD's latest. Paper culture, three-tier appeals, pro-se tolerance

From the 2019 JFBA Policy to 2026 Implementation

Substantive digitalization discussions began around 2018. In June of that year, the Cabinet Secretariat's "Study Group on IT in Court Procedures" issued a report proposing the e-Filing/e-Case/e-Court three-pillar framework that became the basis for the current design.

In September 2019, the Japan Federation of Bar Associations (JFBA) issued the "Basic Policy on Pro-Se Support during Civil-Procedure Digitalization." It explicitly flagged the concern that pro-se litigants could be locked out of the benefits of digitalization, and proposed a three-tier support framework: ICT support, procedural support, and legal advice. The JFBA's decision to put pro-se support on the agenda alongside digitalization influenced the design that followed.

In May 2022, the Diet enacted the amended Code of Civil Procedure (Act No. 48 of 2022). The Integration Act passed in June 2023, extending electronic procedures to related domains including family, civil execution, civil preservation, and bankruptcy. Staged implementation began in March 2023, and May 21, 2026 was set as the full-implementation date.

A seven-plus-year implementation runway is unusually long by international standards. A Stanford Law School working paper characterizes Japan's electronic-civil-procedure reform as "among the latest of OECD countries."

Why Japan Was Late

Japan's delay in electronic civil procedure is not the product of a single cause but the convergence of several structural factors.

First, deeply entrenched paper practice. Judgments, briefs, and evidence have long been bound on paper and stamped with seals. This is shared across the entire ecosystem of registration and contract practice, so digitalizing only litigation faced strong inertia.

Second, the three-tier appeals architecture. When a district-court judgment is appealed to a high court or the Supreme Court, the record physically moves between courts. Digitalization requires all three tiers to align simultaneously, raising system-integration difficulty.

Third, tolerance for pro-se litigation. Japan permits pro-se litigation broadly (there is no mandatory-counsel rule), an institutional choice that matters for access to justice. Rushing digitalization risks locking out pro-se litigants, so pro-se support had to be designed in parallel.

Fourth, the time required to build mints. The Supreme Court chose to develop mints in-house, foregoing reuse of foreign systems like the U.S. CM/ECF or Singapore's eLitigation, which extended the design-and-verification timeline.

International Comparison: When Did Major Jurisdictions Digitalize?

A side-by-side view sharpens the picture.

CountryYear of full electronic litigationAttorney mandate
Singapore2000 (EFS, later renewed as eLitigation/iELS)Mandatory
United States (federal)2002 (CM/ECF, district courts staged; nationwide by 2007)Mandatory
South Korea2011 (electronic litigation)Mandatory
Germany2018 (beA electronic brief system) / 2022 mandateMandatory
JapanMay 21, 2026 (mints full implementation)Mandatory

Singapore pioneered full electronic litigation in 2000 with the Electronic Filing System (EFS, later renewed as eLitigation/iELS). The U.S. CM/ECF (Case Management/Electronic Case Filing) rolled out in bankruptcy courts from 2001 and in federal district courts from May 2002, reaching near-universal adoption by 2007. Korea digitalized civil procedure in the 2010s and reached world-leading utilization rates. Germany introduced the attorney-mailbox system beA in 2018 and made electronic submission by attorneys mandatory from 2022. Japan's 2026 implementation lags these by roughly a decade or more.

Lateness is not unambiguously bad. There is a "follower's advantage": one can observe and learn from the design flaws of leading systems. For example, U.S. CM/ECF has been criticized for complex fee structures that burden pro-se litigants. According to the Ministry of Justice, Japan's regime plans to reduce fees for cases filed via internet — a design move enabled in part by being late.

Reading the Structure

Pro-se rate 20%→7% in a decade. Digitalization fixes physical, not economic/cognitive access

What "the 7% Pro-Se Era" Means

Here is the core figure of this article. The share of district-court ordinary civil litigation cases in which both parties appear pro-se has fallen from approximately 20% to 7% over roughly a decade.

Both-Parties Pro-Se Litigation: 20% → 7% in a Decade
Pro-se litigation was already shrinking to a third before digitalization began
~10 years ago
20%

The Digitalization Paradox
Pro-se litigation was already trending downward. The population that least benefits from digitalization is structurally shrinking — while the latent unfiled cases of those who cannot afford counsel remain invisible.

Decline in both-parties-pro-se civil litigation rate at district courts (~20% to 7% over a decade) and plaintiff attorney engagement rate (Supreme Court Databook 2024, Judicial Statistics)

A commentary by Nishitenma Comprehensive Law Office citing the Court Databook 2024 reports that what was once about 20% both-parties-pro-se litigation began declining roughly a decade ago and fell to 7% by 2023. On the plaintiff side, approximately 90% retain counsel.

How should we read these numbers? On the surface, "access to justice has improved; more people can afford an attorney." That is only partially correct. The decline of pro-se litigation reflects two distinct dynamics combined.

First, possibly improved access to legal services. The civil legal-aid program of Hōterasu, which launched in 2006, has seen rising caseloads and has made it easier for lower-income litigants to obtain counsel.

Second, an increase in "latent unfiled cases." People who cannot afford an attorney, do not feel confident handling pro-se litigation, and ultimately abandon legal action — these cases never appear in judicial statistics. The 7% figure represents people who undertook pro-se litigation, not people who could not.

Where does digitalization act in this structure? For pro-se litigants, online filing, electronic record inspection, and web-conference participation offer benefits, while operational learning, device readiness, and electronic authentication add new barriers. Whether the JFBA's three-tier support is actually present in a given region will substantially shape outcomes.

The Digitalization Paradox

A paradox emerges from this.

The population that benefits least from digitalization — pro-se litigants — has already shrunk structurally to a small minority. Digitalization may shrink it further. The displaced share would flow into "represented litigation," which can be read as improved access to justice. But it can also be read as a sorting effect: "Access improves for those who can afford counsel; it worsens for those who cannot."

Not all sorting effects are bad. Receiving professional assistance in litigation is, in general, beneficial for the litigant. The problem is that the design accompanying the sorting — "how do we support those who cannot afford counsel?" — is relatively under-emphasized in the digitalization discussion. Press coverage shines light on convenience and efficiency; regional disparities in pro-se support rollout and the pace of Hōterasu expansion go unmentioned.

Three Layers of Access and Article 32

The right to trial is guaranteed by Article 32 of the Constitution of Japan. The Code of Civil Procedure is the foundational statute that gives that right concrete procedural form. When the procedure itself changes substantially, the content of the right is reconstructed.

Access to justice can be evaluated across three layers.

Layer One: Physical access — the courthouse's physical location and the time required to navigate procedures. For small-claims litigants in rural areas, the burden of multi-hour round trips to the nearest district court was heavy. Digitalization clearly improves this layer. Once web-conference hearings, remote electronic record inspection, and online filing are in place, travel costs drop sharply.

Layer Two: Economic access — attorney fees, court fees, stamp fees. Digitalization includes planned fee reductions for online filing, so the court-fee dimension improves modestly. But attorney fees themselves do not change. Hōterasu's civil legal aid has income and asset thresholds; the "middle layer" excluded from aid still bears heavy attorney costs. Economic access is largely outside digitalization's range of effect.

Layer Three: Cognitive access — the ability to understand procedure, draft documents, and frame issues. This is the least visible layer. Carrying a pro-se case to completion requires legal knowledge, drafting ability, and issue-framing capacity, all of which depend on education, occupational experience, and intellectual training. Digitalization adds operational learning as new cognitive load, so on cognitive access, it can act in the direction of higher barriers.

So digitalization substantially improves Layer One, partially improves Layer Two, and may worsen Layer Three. For the right to trial to be fully realized, digitalization must run in parallel with strengthened pro-se support (cognitive access) and expanded civil legal aid (economic access).

Design Issues Left Open

Three issues should be foregrounded post-implementation.

First, standardization of pro-se support windows. Whether the three-tier support framework proposed in the JFBA's 2019 policy is uniformly delivered across district and summary courts nationwide needs post-launch verification. Current disparities between mid-sized regional cities and Tokyo risk transcribing geographic and economic disparities into judicial access.

Second, making "latent unfiled cases" visible. People who abandon litigation because they cannot afford counsel do not appear in judicial statistics. Triangulating Hōterasu civil-legal-aid caseloads, free-legal-consultation inquiries, and "we are not considering litigation" responses on consumer-affairs surveys can produce rough estimates of the latent volume. The limitation of measuring access to justice solely by filed-case counts should be revisited at implementation.

Third, the position of judicial scriveners and paralegals. The Japan Federation of Shihō-Shoshi Lawyer's Associations and the Federation of Young Shihō-Shoshi Associations are actively integrating pro-se support into shihō-shoshi practice. Certified shihō-shoshi with summary-court representation authority can represent parties in summary-court civil matters up to ¥1.4 million in claim value, positioning them as a bridge between the pro-se and represented layers. mints accommodates shihō-shoshi as well, which directly affects on-the-ground pro-se support.

As discussed in the sister column "Maina-Insurance Card Structure: Pro-Se Support Design in Healthcare DX", healthcare DX similarly surfaced pro-se support for older adults and digitally-marginalized populations. Judicial DX's pro-se support design has much to learn from the healthcare-DX precedent. Watching the trio — administrative DX / healthcare DX / judicial DX — as a single horizontal frame is increasingly necessary for institutional evaluation.

May 21 is not the finish line. It is the starting line for pro-se support and access redesign. Behind the convenience headlines, how thoroughly support for the less visible layers is embedded will be tested in post-implementation operation. For an item-by-item account of the three-pillar design and the staged rollout logic, see Kazuhiko Yamamoto, 『民事裁判手続のIT化』 (Digitalization of Civil Procedure) (Kōbundō, 2023), authored by a scholar deeply involved in drafting the amendment.

Questions to Reflect On

  1. Given that pro-se litigation has already declined to 7%, where should the priority of pro-se support infrastructure rank in the institutional design of the reform?
  2. The "latent unfiled cases" of those who abandon litigation because they cannot afford counsel do not appear in judicial statistics. Are current mechanisms (Hōterasu civil legal aid, judicial scriveners, free legal consultations) sufficient to surface these cases?
  3. Evaluating the right to trial across physical, economic, and cognitive access layers — which of the three does digitalization improve, and which does it leave untouched (or worsen)?
