5.2 High Courts

Structure of High Courts

Japan's High Courts sit just below the Supreme Court, making them the second-highest tier in the judicial system. Their primary job is appellate review: they examine whether lower courts got the law right and applied it correctly. Because the Supreme Court accepts relatively few cases, the High Courts are often the last stop for most appeals.

Composition and Jurisdiction

Each High Court case is heard by a three-judge panel, typically made up of a presiding judge and two associate judges. Their jurisdiction covers appeals from District Courts, Family Courts, and Summary Courts within their geographic region.

There are eight High Courts spread across Japan's major cities:

• Tokyo, Osaka, Nagoya, Hiroshima, Fukuoka, Sendai, Sapporo, and Takamatsu

Each one covers a defined territorial area, so the High Court you appeal to depends on where your case originated. In addition, the Intellectual Property High Court in Tokyo is a specialized branch that handles patent, trademark, and other IP disputes nationwide.

Appellate Function

When a High Court takes an appeal, it reviews the lower court's decision for errors in either fact-finding or application of law. The court can conduct a fresh examination of evidence and legal arguments, though in practice, new evidence is rarely introduced (more on that below).

After review, the High Court may:

• Affirm the lower court's decision (uphold it as correct)
• Reverse the decision (overturn it entirely)
• Modify the decision (change parts of it while keeping others)

This process helps maintain consistency in how laws are interpreted across different regions of the country.

Special Divisions

High Courts contain specialized divisions to handle different types of cases:

• Intellectual Property High Court handles complex patent and trademark disputes (this is a distinct court within the Tokyo High Court structure)
• Administrative division focuses on cases involving challenges to government actions and regulations
• Labor division deals with employment disputes and labor law questions
• Criminal division handles appeals in criminal cases exclusively

Not every High Court has all of these divisions. The larger courts (Tokyo and Osaka especially) tend to have more specialized panels.

Role in the Judicial System

High Courts do more than just hear appeals. They serve several functions that keep the broader judicial system running smoothly.

Intermediate Appellate Courts

The High Courts act as a filter between District Courts and the Supreme Court. This is significant because the Supreme Court has discretionary review powers, meaning it chooses which cases to hear. For many litigants, the High Court decision is effectively final.

By providing a thorough second level of review, High Courts reduce the Supreme Court's caseload while still giving parties a meaningful chance to challenge lower court errors.

Supervision of Lower Courts

High Courts have an oversight role within their jurisdiction. They conduct inspections of lower courts to ensure proper administration of justice and provide guidance on legal interpretations and procedural matters. When patterns of errors emerge in lower court decisions, the High Court can address those systemic issues.

Administrative Responsibilities

Beyond deciding cases, High Courts manage judicial resources and personnel in their region. They coordinate with the Supreme Court on policy implementation and judicial reforms, and they oversee training programs for judges and court staff.

High Court Procedures

The appeal process follows a structured sequence designed to balance thorough review with timely resolution.

Filing Appeals

1. Meet the deadline. Appeals must be filed within 14 days of the lower court's decision for criminal cases, and within two weeks for civil cases.
2. Submit a written statement. The appellant must outline the specific grounds for appeal and identify the legal errors they believe the lower court made.
3. Pay court fees. Filing fees are required, though fee waivers are available for those who demonstrate financial hardship.

Missing the filing deadline means losing the right to appeal, so this is a strict requirement.

Oral Arguments

Once the appeal is accepted, parties present their cases before the three-judge panel in a formal court session.

• Lawyers argue legal points and highlight key evidence from the lower court record
• Judges may ask questions to clarify arguments or request additional information
• New evidence is generally not permitted unless the party can show it was unavailable during the original trial

This last point is important: the High Court is primarily reviewing what happened below, not conducting a brand-new trial.

Decision-Making Process

1. After oral arguments, the three judges deliberate in private.
2. They reach a decision by majority vote (so a 2-1 split is sufficient).
3. The court prepares a written opinion explaining its reasoning, including any dissenting views.
4. The decision is announced in open court and made available to the parties and the public.

Types of Cases Handled

High Courts hear a wide variety of cases, reflecting their broad appellate jurisdiction.

Civil and Criminal Appeals

• Criminal appeals involve review of convictions and sentences, checking whether criminal law and procedure were properly applied
• Civil appeals cover contract disputes, property rights, personal injury claims, and similar matters
• Family law appeals address divorce, child custody, and inheritance issues that were first decided in Family Courts

Administrative Litigation

These cases involve challenges to government power:

• Citizens or businesses disputing government actions, regulations, or administrative decisions
• Tax disputes between taxpayers and tax authorities
• Immigration cases, including deportation orders and refugee status determinations

Election Disputes

High Courts play a role in protecting democratic processes. They adjudicate challenges to election results or procedures at both local and national levels, interpret election laws, and handle cases involving campaign finance violations or voter fraud allegations.

Relationship with the Supreme Court

The High Courts and the Supreme Court work within a hierarchical system where the Supreme Court has the final word, but the High Courts do much of the heavy lifting on appellate review.

Referral of Cases

• High Courts may refer cases involving constitutional questions directly to the Supreme Court
• Cases of national significance can be recommended for Supreme Court review
• The Supreme Court may also request that High Courts provide opinions on specific legal issues

Binding Precedents

High Courts are bound by Supreme Court precedents. When the Supreme Court issues a ruling, that interpretation of law is authoritative for all lower courts, including the High Courts. In practice, High Courts spend much of their time applying and interpreting Supreme Court precedents within the specific facts of individual cases.

Judicial Review

High Courts conduct initial reviews of cases that raise constitutional questions. They have the power to uphold or strike down laws and regulations based on constitutionality, but these decisions are always subject to potential Supreme Court review. Any High Court ruling on a constitutional matter can be appealed to the Supreme Court for final determination.

This layered review process ensures that constitutional questions receive careful analysis at multiple levels before a final answer is reached.
