A federal judge has rejected a Manhattan doctor’s effort to stop his extradition to Japan, bringing to a close nearly a decade of litigation that raised critical questions about international extradition law, religious freedom, and the rights of dual citizens and permanent residents facing foreign prosecution.
According to reporting by The New York Times, Dr. Masahide Kanayama, a 63-year-old surgeon who has practiced medicine in Manhattan for nearly three decades, faces charges in Japan for allegedly vandalizing two ancient religious sites in 2015. His attorney, Michael Zigismund of the Law Offices of Robert Tsigler, PLLC, argued that the case represents religious persecution and raised serious concerns about fairness in the Japanese legal system.
“Our position has been, and is, if any case were to be an edge case, it would be exactly this case,” Mr. Zigismund told the court. “The unfortunate thing is, there aren’t too many days left.”
The case highlights important issues that many people don’t consider until they’re directly affected: What happens when a foreign government requests your extradition? What rights do you have? Can you fight extradition even if you’re a U.S. citizen or permanent resident? And what factors do courts consider when deciding whether to send someone to face charges abroad?

Understanding how extradition works and what defenses may be available is crucial for anyone facing foreign criminal charges.
What Is Extradition?
Extradition is the formal process by which one country surrenders an individual to another country to face criminal charges or serve a sentence. The United States has extradition treaties with over 100 countries, establishing the legal framework for these transfers.
How Extradition Treaties Work
When countries sign an extradition treaty, they agree to honor certain requests to surrender individuals wanted for crimes. However, these treaties typically include important limitations and requirements:
Dual Criminality – The alleged conduct must be criminal in both countries. For example, the United States generally won’t extradite someone for conduct that isn’t also a crime under U.S. law.
Severity Threshold – Most treaties only apply to offenses punishable by a minimum sentence, often one year or more. Minor offenses typically don’t qualify for extradition.
Political Offense Exception – Most treaties exclude “political offenses” from extradition, though what qualifies as political is often disputed.
Death Penalty Restrictions – Some treaties limit extradition when the requesting country might impose the death penalty, unless assurances are provided.
Nationality Exceptions – Some countries, including many in Europe, generally refuse to extradite their own citizens. The U.S.-Japan treaty, however, allows for extradition of nationals from both countries.
The Extradition Process in the United States
When a foreign government requests extradition, the process follows several steps:
- Diplomatic Request – The foreign government submits a formal extradition request through diplomatic channels to the U.S. State Department.
- Judicial Review – A federal judge evaluates whether the treaty requirements are met and whether there’s probable cause to believe the person committed the alleged offense.
- Certification – If the judge finds extradition is appropriate, they certify the person as extraditable to the Secretary of State.
- Executive Decision – The Secretary of State makes the final decision on whether to surrender the individual, though this discretion is rarely exercised to deny extradition once certified.
- Appeals – The person can seek habeas corpus relief in federal court, challenging various aspects of the extradition.
In Dr. Kanayama’s case, this process has been ongoing since Japan requested his extradition in 2016, with federal agents arresting him in 2017 and multiple courts rejecting his challenges over nearly a decade.
The U.S.-Japan Extradition Treaty
The United States and Japan have maintained an extradition treaty since 1980. Understanding the specific provisions of this treaty is important for anyone who might be subject to extradition between these countries.
Key Requirements Under the U.S.-Japan Treaty
Extraditable Offenses – The treaty covers offenses punishable under the laws of both countries by death, life imprisonment, or imprisonment for more than one year.
Double Criminality – The conduct must constitute a crime under both U.S. law and Japanese law. In Dr. Kanayama’s case, according to court documents, he was accused of damaging property – conduct that constitutes vandalism in both countries.
Probable Cause – The requesting country must provide sufficient evidence to establish probable cause that the person committed the offense. This is a lower standard than proof beyond reasonable doubt required for conviction.
National Treatment – Unlike some European countries, both the United States and Japan can extradite their own citizens under the treaty, though they’re not required to do so.
What the Treaty Doesn’t Require
The extradition treaty does not require the United States to evaluate:
- Whether the foreign prosecution is fair or politically motivated
- The conditions in foreign prisons
- Whether the defendant would receive rights equivalent to U.S. constitutional protections
- The harshness of potential sentences under foreign law
This limited scope of review is why challenging extradition can be extremely difficult, even in cases raising serious concerns about fairness or human rights.
Grounds for Challenging Extradition
Despite the limited scope of judicial review, there are several bases on which extradition can be challenged.
Lack of Dual Criminality
If the alleged conduct isn’t criminal under U.S. law, extradition should be denied. This requires careful analysis of both what the person is accused of doing and how U.S. law would characterize that conduct.
In Dr. Kanayama’s case, his attorneys initially argued that his actions didn’t constitute criminal damage under U.S. law. According to The New York Times, his lawyers maintained “that he did not vandalize any religious sites, and that ‘his actions damaged nothing.'” However, courts found that the alleged conduct – applying oil to property causing approximately $21,300 in damage – would constitute criminal damage in the United States.
Insufficient Probable Cause
The requesting country must provide competent evidence establishing probable cause to believe the person committed the offense. Defense attorneys can challenge the sufficiency or reliability of this evidence.
The Japanese government provided surveillance footage, car rental records, toll records, flight records, and YouTube videos showing someone Japanese officials identified as Dr. Kanayama discussing anointing shrines with oil. Courts found this evidence sufficient to establish probable cause.
Treaty Violations
If the requesting country violated provisions of the extradition treaty, this can form a basis to challenge extradition. This might include:
- Requesting extradition for an offense not covered by the treaty
- Failing to provide required documentation
- Seeking extradition for political purposes disguised as criminal charges
Religious or Political Persecution
While U.S. courts generally don’t evaluate the fairness of foreign legal systems, allegations of persecution based on religion, race, or political views can sometimes provide grounds to resist extradition.
As Mr. Zigismund argued in Dr. Kanayama’s case: “Why would the government of Japan focus its resources so heavily on Dr. Kanayama as opposed to so many others who have similar vandalism charges against themselves? The answer is precisely because of Dr. Kanayama’s position in the religious world. He’s the head or one of the heads of a particular branch of Christianity that is on the outs in Japan.”
However, proving religious or political persecution in extradition proceedings is extremely difficult. The Japanese Consulate General in New York stated that the extradition request was “based strictly on law and evidence” and “is in no way motivated by political or religious considerations.”
Violations of Due Process
Courts can consider whether fundamental due process rights were violated during the extradition proceedings. This doesn’t extend to evaluating the foreign country’s legal system, but rather focuses on whether U.S. proceedings were fair.
Rights of U.S. Citizens vs. Permanent Residents in Extradition Cases
A common misconception is that U.S. citizenship provides absolute protection against extradition. The reality is more nuanced.
U.S. Citizens Can Be Extradited
The U.S. government routinely extradites U.S. citizens to foreign countries under extradition treaties. Citizenship provides some protections, but it doesn’t create a blanket exemption from extradition.
However, U.S. citizens facing extradition have important rights:
- Right to judicial review of the extradition request
- Right to counsel
- Right to challenge the extradition through habeas corpus proceedings
- Right to appeal adverse decisions
Permanent Residents Face Similar Treatment
Legal permanent residents (green card holders) are subject to extradition on essentially the same terms as U.S. citizens. Dr. Kanayama’s status as a Japanese citizen and U.S. permanent resident didn’t provide any special protection against extradition to Japan.
Permanent residents should be aware that:
- Extradition doesn’t automatically affect immigration status, but
- Criminal convictions abroad can lead to deportability and removal of permanent resident status
- Extended absence from the U.S. due to foreign incarceration can jeopardize permanent residency
Dual Citizens Face Unique Complications
People with dual citizenship, like Dr. Kanayama (both Japanese and potentially seeking U.S. citizenship), can face particular challenges:
- The country of their other citizenship may have stronger claims for extradition
- They may be treated as nationals by the requesting country, potentially affecting their legal rights
- Some countries provide fewer protections to dual nationals than to foreign citizens
The Human Cost of Extradition Cases
Beyond the legal technicalities, extradition cases involve profound human consequences that courts often cannot consider but that are very real for the people involved.
Dr. Kanayama’s Case Illustrates the Stakes
According to The New York Times, Dr. Kanayama is “a surgeon and expert in endometriosis” whose “patients have said his surgeries ended years of crippling pain and, in some cases, allowed them to have children.” He has practiced medicine in Manhattan for nearly three decades, building a life and career in the United States.
If convicted in Japan, he faces up to five years of hard labor – a sentence that would effectively end his medical career and separate him from his patients, his practice, and the life he’s built in America.
Broader Implications for Professionals and Business People
The Kanayama case raises concerns for many people who maintain ties to their countries of origin:
International Business People – If you conduct business abroad, allegations of financial crimes, regulatory violations, or other offenses could lead to extradition requests years later.
Dual Citizens – Maintaining citizenship in your country of birth while living in the U.S. can subject you to claims of jurisdiction by that country.
Religious Missionaries – Those who engage in religious activities abroad may face particular risks in countries hostile to certain religions.
Political Activists – Criticism of foreign governments, even from the United States, can lead to criminal charges and extradition requests.
The Lengthy Process
As Dr. Kanayama’s nearly decade-long legal battle demonstrates, fighting extradition is often a lengthy process. During this time:
- You may be required to surrender your passport
- You may need to post bail or remain in custody
- Your ability to work and support your family may be impaired
- You live under the constant stress of potential removal
- Legal fees can be substantial
What to Do If You’re Facing Potential Extradition
If you learn that a foreign government is seeking your extradition, or if you’re concerned this might happen, taking immediate action is crucial.
Contact an Experienced Federal Criminal Defense Attorney
Extradition cases involve complex intersections of international law, federal criminal procedure, and immigration law. You need an attorney with specific experience in these matters.
An experienced criminal defense attorney can:
- Evaluate the strength of the extradition request
- Identify potential defenses and challenges
- File motions to contest the extradition
- Negotiate with federal prosecutors and the State Department
- Seek habeas corpus relief if extradition is certified
- Appeal adverse decisions through the federal court system
Do Not Speak to Law Enforcement Without Your Attorney
If federal agents or foreign law enforcement contact you about potential criminal charges abroad:
- Invoke your right to remain silent
- Do not try to explain or defend yourself
- Do not agree to voluntary interviews
- Contact an attorney immediately
Statements you make can be used against you both in extradition proceedings and in any foreign prosecution.
Gather Important Documents
Collect any documentation that might be relevant to your defense:
- Travel records showing your locations on relevant dates
- Business or personal documents contradicting the allegations
- Evidence of your ties to the United States
- Medical records or other documentation of conditions that might be relevant
Consider Immigration Implications
If you’re a permanent resident, understand how extradition and any foreign conviction could affect your immigration status. You may need both criminal defense counsel and an immigration attorney working together to protect your interests.
Don’t Flee or Hide
Failing to appear for extradition proceedings or fleeing to avoid extradition will only make your situation worse:
- You may face additional criminal charges for flight
- It eliminates many legal defenses
- You’ll live as a fugitive, unable to work legally or live normally
- It can lead to international warrants and arrest if you travel
Why Experienced Legal Representation Matters in Extradition Cases
The outcome of Dr. Kanayama’s case, despite years of litigation and appeals to the highest court, demonstrates both how difficult extradition cases are to win and why skilled legal representation is essential.
Expertise in International Law
Extradition cases require understanding:
- The specific provisions of bilateral extradition treaties
- International human rights law
- Federal criminal procedure
- Habeas corpus practice
- Appellate advocacy
Attorney Michael Zigismund’s representation of Dr. Kanayama through nearly a decade of proceedings showcases the dedication and expertise required in these complex cases.
Strategic Decision-Making
Experienced attorneys know when to:
- Challenge the sufficiency of evidence
- Raise treaty interpretation issues
- Argue constitutional violations
- Seek stays pending appeal
- Negotiate with prosecutors and State Department officials
As Mr. Zigismund noted about the Kanayama case, even “edge cases” require sophisticated legal strategy and persistent advocacy.
Protecting Your Rights at Every Stage
From the initial arrest through final appeals, every stage of extradition proceedings involves important rights that must be protected:
- Bail hearings
- Extradition certification hearings
- Habeas corpus proceedings
- Appeals to Circuit Courts
- Emergency applications to the Supreme Court
Understanding When Cases Are Worth Fighting
Experienced counsel can help you understand realistically:
- The strength of potential defenses in your case
- The likelihood of success at various stages
- Whether the time and expense of fighting extradition makes sense
- What alternatives might be available
International Cooperation and U.S. Foreign Policy
It’s important to understand the broader context in which extradition decisions are made.
Strong Interest in Honoring Treaties
As Judge Oetken noted in his ruling on Dr. Kanayama’s case, “the United States had a strong interest in honoring extradition treaties with other countries.” Federal courts recognize that extradition is not just a legal matter but also implicates foreign relations and international cooperation.
This means that courts are often reluctant to deny extradition requests from treaty partners, even in cases raising concerns about fairness or the severity of potential punishment.
Reciprocity Matters
The United States depends on other countries honoring U.S. extradition requests to bring fugitives back to face justice. Denying foreign extradition requests could jeopardize this cooperation.
Limited Evaluation of Foreign Legal Systems
U.S. courts generally won’t evaluate whether:
- The foreign country’s legal system is fair
- Prison conditions meet U.S. standards
- The defendant would receive rights equivalent to U.S. constitutional protections
- Sentences seem disproportionate by U.S. standards
The assumption is that treaty partners have adequate legal systems, even if different from ours.
Frequently Asked Questions
Can I be extradited for something that isn’t a crime in the United States?
Generally no. Most extradition treaties, including the U.S.-Japan treaty, require “dual criminality” – meaning the conduct must be criminal in both countries. However, the conduct doesn’t need to be charged under identical laws or carry identical penalties.
If I’m a U.S. citizen, can I still be extradited?
Yes. U.S. citizenship doesn’t provide blanket protection against extradition. The United States regularly extradites its own citizens to foreign countries under extradition treaties.
What if I’m accused of a political crime?
Most extradition treaties exclude “political offenses,” but what qualifies as political is narrowly interpreted. Criminal conduct doesn’t become non-extraditable just because it has political motivations or implications.
Can religious persecution be a defense to extradition?
While allegations of religious persecution can be raised, they’re very difficult to prove in extradition proceedings. Courts generally defer to the foreign government’s characterization of the charges unless there’s clear evidence the prosecution is pretextual.
How long does the extradition process take?
It varies significantly. Some cases resolve in months, while others – like Dr. Kanayama’s – can take years or even a decade. The timeline depends on the complexity of legal issues, the number of appeals, and various procedural factors.
Can I be extradited for minor offenses?
Most treaties only apply to offenses punishable by a minimum sentence, typically one year or more. Very minor offenses generally don’t qualify for extradition.
What happens if I’m convicted abroad and serve time there?
If you’re a U.S. citizen, the U.S. government may be able to help ensure you’re treated fairly, but has limited ability to interfere with foreign legal processes. If you’re a permanent resident, foreign convictions can affect your immigration status and may lead to deportation upon your return.
Can the U.S. refuse to extradite me even if treaty requirements are met?
Theoretically yes – the Secretary of State has discretion to deny extradition even after judicial certification. In practice, this discretion is rarely exercised, and the State Department generally defers to judicial determinations.
What if I have family and business ties in the United States?
Unfortunately, these personal factors typically aren’t relevant to extradition determinations. Courts focus on legal requirements of the treaty, not hardship to the individual or their family.
Should I voluntarily return to face charges instead of fighting extradition?
This is a strategic decision that should only be made with advice from experienced counsel. In some cases, voluntary return may allow better negotiation of charges or bail conditions. In others, fighting extradition may be the only way to avoid unjust prosecution.
