TLDR: Japan runs civil cases very differently from the US, UK, Canada or Australia. Judges drive the process, there are no civil juries, and there’s no broad discovery. Hearings come in short sessions spread over months, and judges push settlement early. If you do business in Japan or might end up in a dispute there, knowing these differences up front saves money and a lot of frustration.

A Civil Law System, Not a Common Law One

Japan follows the civil law tradition, which puts it closer to Germany and France than to England or the US. The Civil Code and the Code of Civil Procedure sit at the center. Judges apply written statutes first and look at past cases second.

What That Means for Precedent

In a common law country, an earlier ruling from a higher court can bind the judge in front of you. Japan doesn’t work that way on paper. In practice, though, Supreme Court decisions carry heavy weight, and lower courts rarely stray from them. So precedent still matters. It just isn’t the engine of the system.

How the Court System Is Built

Japan has four levels. Summary courts handle smaller claims, and district courts take most first-instance civil cases. High courts hear appeals, and the Supreme Court sits at the top, taking only a narrow set of cases.

Small Claims and Summary Courts

Summary courts deal with claims up to about 1.4 million yen. There’s also a small claims procedure for disputes up to 600,000 yen, designed to wrap up in a single hearing in most cases. Compare that with small claims courts in the US or Australia, where limits and formality vary a lot by state. Japan’s version is quick but also strict about what evidence you can bring on the day.

Judges Run the Show

Common law courts are adversarial. Lawyers control the evidence, call the witnesses and shape the story, while the judge acts as referee. Japanese judges take a much more active role. They ask questions, press parties to clarify their positions, and decide which issues deserve attention. There’s no jury in civil cases, so a panel of professional judges (or a single judge) decides everything.

Hearings Come in Short Bursts

A US trial might run for days in one block. Japanese civil cases usually don’t. Instead you get a series of short hearings, often a month or so apart, where the parties exchange written statements and the court narrows the issues. Witness testimony tends to be saved for the end and compressed into one or two sessions. It feels slow if you’re used to a courtroom showdown, but it often means the final stage is short and well organized.

Evidence and the Discovery Gap

This is where common law lawyers get a shock. Japan has no equivalent of US-style discovery. There are no depositions and no sweeping demands for every email on a topic. Parties can ask the court to order the other side to produce specific documents, and there are tools for asking the other party questions. But the reach is narrower, and the person making the claim usually has to gather most of their own proof before filing.

That puts real weight on paperwork. Contracts, emails, meeting notes and invoices matter far more when you can’t pull the other side’s files out of them. Written witness statements are also common, and they often carry as much weight as live testimony.

Settlement Is Pushed Early

Japanese judges openly encourage settlement, sometimes more than once during a case. A judge may share a preliminary view of the dispute and then suggest terms. Court-run conciliation is also widely used, especially for family, tenancy and neighbor disputes. Common law countries encourage settlement too, but usually through mediation orders or cost penalties. In Japan, the judge is often the one steering you to the table.

Costs, Damages and Who Pays

The losing side generally pays court fees, but not the other side’s full legal bill. In some tort claims, a portion of lawyer fees can be added to the damages award, but that’s the exception. Damages are also meant to compensate, not punish. Japan’s courts don’t award punitive damages, and the Supreme Court has refused to enforce foreign punitive awards.

Class actions are limited too. There’s a collective redress system for consumer claims, but it’s narrow compared with US class actions or group proceedings in Australia and Canada.

What This Means for Foreign Businesses

If a dispute could land in a Japanese court, a few habits help:

• Keep clear written records from day one, because evidence is hard to compel later.
• Hire a local lawyer early, since procedure and judicial style differ sharply.
• Plan for a longer timeline than a hearing-by-hearing view suggests, and expect translation work.
• Be ready to talk settlement before the case reaches its final stage.

Japan has also been phasing in electronic filing and online hearings, so some of the older, paper-heavy habits are changing.

None of this makes Japan’s system better or worse than a common law one. It’s built on different assumptions about who controls a case and how the truth comes out. If you’re facing a real dispute, talk to a qualified lawyer who works in the right jurisdiction.
