What Japanese Legal Practice Is Missing — and Why It Matters
I. The Problem: Intellectual Laziness Disguised as Legal Rigor
When Japanese lawyers cite human rights provisions in constitutional litigation, the act often functions not as legal analysis but as legal ritual. Articles 13, 14, 21, and 25 are enumerated; their alignment with specific statutes is examined; arguments are constructed to fit within the boundaries courts have previously recognized. This is, to be sure, “legal reasoning.” But it is not design.
The problem lies not in competence but in the framework of thought. Japanese bar examinations and law school curricula train practitioners rigorously in deductive reasoning: statute → requirement → effect. This training is precise — but it simultaneously internalizes a self-imposed constraint: think within the boundaries of existing law. Lawyers become optimizers within a given framework rather than architects of the framework itself.
This self-constraint extends beyond human rights litigation into corporate practice. Counsel reflexively selects Japanese law and the Tokyo District Court, unable to design contracts that account for the extraterritorial reach of EU regulations or other mandatory foreign rules. In international arbitration, the three-axis design logic — tribunal composition strategy, procedural tactics, and reverse-engineering from enforcement — is largely absent. Mediation is understood passively as a “procedure for compromise.” The lawyer as designer is simply not present.
II. The Constitutional Preamble and Article 98(2): An Unused Blueprint
The Constitution of Japan is not merely a catalog of rights provisions. It is a document that explicitly architects a connection to international law. That blueprint is inscribed in two places: the Preamble and Article 98, paragraph 2.
[Constitution of Japan — Preamble (excerpt)]
We, the Japanese people, desire peace for all time and are deeply conscious of the high ideals controlling human relationship, and we have determined to preserve our security and existence, trusting in the justice and faith of the peace-loving peoples of the world. We desire to occupy an honored place in an international society striving for the preservation of peace, and the banishment of tyranny and slavery, oppression and intolerance for all time from the earth. We recognize that all peoples of the world have the right to live in peace, free from fear and want.
[Constitution of Japan — Article 98, Paragraph 2]
The treaties concluded by Japan and established laws of nations shall be faithfully observed.
The Preamble is not a mere declaration of ideals. The phrase “trusting in the justice and faith of the peace-loving peoples of the world” declares that Japan’s security and existence rest on a relationship of good faith with the international community. The recognition that “all peoples of the world have the right to live in peace, free from fear and want” places domestic rights concepts in the context of universal human rights. This is not rhetoric — it is a normative declaration with legal reach.
The reach of the obligation to “faithfully observe” under Article 98(2) is not limited to ratified treaties. “Established laws of nations” encompasses customary international law — and even for unratified treaties, there is room to ask whether the very condition of non-ratification conflicts with the duty of faithful observance under international law. Connecting the logical structure of unconstitutional legislative inaction to inaction under international law: here lies a legal frontier that Japanese practitioners have barely touched.
To make this concrete: constructing the selective surname issue as “internationally unlawful legislative inaction” by routing CEDAW and Human Rights Committee recommendations through Article 98(2); challenging the inaction of Japan’s non-ratification of the Second Optional Protocol to the ICCPR on the death penalty; framing the anomalously low refugee recognition rate through the principle of non-refoulement — all of these are arguments fully available once the Preamble and Article 98(2) are activated as design principles.
III. Two Failures: The Inward Lawyer and the Outward “Internationalist”
The epistemic gap in Japanese legal practice originates from two directions. On one side are lawyers who treat international law as a footnote, self-constrained within domestic legal frameworks. On the other are practitioners bearing US or UK qualifications who call themselves “international lawyers” while providing, in substance, little more than external critique.
The problem of the latter mirrors that of the former. The process by which an LL.M. program overlays common law thinking often repositions the internal logic of Japanese law as a “premise to be overcome.” That structure persists upon return: describing Japanese institutions, culture, and decision-making patterns as inferior relative to “global standards” becomes the default analytical posture. “Japan does not do XXX.” “Japan is inconsistent with OECD standards.” The form of critique becomes the substance of thought.
Yet both share a deeper, common problem: the Galapagos framework — the assumption that “Japan is uniquely exceptional.” The inward lawyer uses it as a shield; the outward internationalist uses it as a critical premise. But the epistemic structure is identical: Japan is isolated from, and then measured against, the world.
IV. Dismantling the Galapagos Myth
Factually, Japan’s legal system is not the product of isolated independent evolution. The reception of law since the Meiji era drew the Civil and Commercial Codes from French and German law, the Meiji Constitution from the Prussian model. The postwar Constitution grafted American liberalism onto Weimar-style social rights, while the Code of Criminal Procedure incorporated elements of Anglo-American adversarial procedure.
Moreover, Japan has ratified the ICCPR, ICESCR, CEDAW, CRC, and CRPD, and is deeply embedded in the WTO agreements, EPA networks, the New York Convention, and the Hague Conventions. To characterize a legal system this thoroughly integrated into the international legal order as “isolated” or “exceptional” is simply factually incorrect.
The same applies to culture. Buddhism arrived as a transformation of Indian thought through the Asian continent; kanji and Confucianism are products of deep connection with Chinese civilization. Modern Japan selectively absorbed Western civilization, developed it in distinctive ways, and transmitted it back to the world. This is not an isolated island culture — it is a culture constituted by continuous connection and transformation.
A more precise conceptual distinction is this: every legal system and culture is particular, but none is isolated. German, French, and Anglo-American law are all particular — yet no one calls them “Galapagos.” The very fact that this frame is applied exclusively to Japan constitutes an epistemic asymmetry — something approaching intellectual discrimination.
V. Japan Connected: The Possibility of the Mediator
Shift the epistemic frame, and Japan’s position changes fundamentally — from “belated recipient” to “particular mediator.”
Japan possesses a legal system — nearly unique in Asia — that has experienced both civil law and common law traditions. Its nearly eighty years of institutional commitment to the pacifist experiment of Article 9 represents a comparative resource of singular value in international law. Geopolitically it sits at the junction of East Asia and the West; culturally it has been a site of transformation and integration across multiple traditions.
This is not exceptionalism — it is a distinctive mediating resource. Here lies the foundation for Japan to position itself not as an object of international legal critique but as an active mediator and originator of legal design. For precisely this reason, the Preamble’s aspiration to “occupy an honored place in an international society” must be reread not as passive peace contribution but as active participation in global legal architecture.
And the obligation to “faithfully observe” under Article 98(2) can be interpreted beyond passive application of existing treaties — as a duty to participate faithfully in the formation of the international legal order. Challenging the inaction of non-ratification falls squarely within the reach of this active duty of faithfulness.
VI. A Closed Epistemic Community — Beyond the Lawyer
The argument developed here reaches further than the legal profession narrowly defined. Prosecutors and judges inhabit the same framework. And precisely because they are more completely enclosed within the institution, the problem is in some respects more acute.
Lawyers at least retain a circuit of contact with the “outside” through their clients. Prosecutors, by contrast, exercise discretion over indictment with no structural incorporation of international legal standards. The practices of prolonged pre-indictment detention and coercive interrogation — repeatedly cited in recommendations from the Human Rights Committee — are processed as external interference rather than obligations under faithfully observed law. Judges, similarly, have produced vanishingly few decisions that activate Article 98(2) in any substantive way. That treaty body interpretations rarely even appear as obiter dicta is not accidental: the Legal Training and Research Institute produces jurists entirely within a domestic legal framework, institutionally reproducing the sense that international legal arguments lie outside the relevant field of vision.
The problem common to all three is that the institution is self-referentially closed. Lawyers, prosecutors, and judges are formed by the same bar examination, the same training institute, and the same culture of legal interpretation — continuously defining “correct legal reasoning” by reference to one another. There is no circuit through which epistemological pressure from outside can enter the system. This is not a question of individual capability. It is a structural closure of the legal profession as an epistemic community. The absence of the lawyer as designer is not a problem of the legal profession as such — it is a problem in the design of Japan’s legal system as a whole.
Conclusion: From Critique to Design
Critique is diagnosis, not treatment. What is missing in Japanese legal practice is neither the capacity to criticize nor the grounds for being criticized. What is missing is the will and the epistemic framework to design.
To design, we must place Japan within the world — not as an isolated exception, but as a particular participant with a history of connection. The Constitutional Preamble is the declaration of that participation; Article 98(2) is its legal obligation. To activate these two provisions as design principles for legal practice — this is what is most urgently needed of Japanese lawyers today.
That design requires the capacity to thread international and domestic law onto a single analytical axis; the ability to hold two linguistic conceptual systems simultaneously and translate between them; and the epistemological training to think from the inside of both sides at once. This is not a matter of credentials. It is a matter of how intelligence holds itself.
A final word on language itself. The Japanese term bengoshi (弁護士), coined during the Meiji-era reception of Western law, shares the same structural problem as its English counterparts — Attorney, Advocate, Solicitor, and even Lawyer. Each fixes a single aspect of the function into the name: defense, representation, post-hoc remedy, or the mere handling of law as a tool. None reflects the practitioner as designer of social relations, mediator between norm and reality, or architect of structures that prevent disputes before they arise. The asymmetry between languages is telling: different words, the same conceptual poverty. This essay uses the term hōritsuka (法律家 — jurist, or simply “person of law”) as a provisional placeholder. A name adequate to the actual calling has yet to be coined.
