Collect a Debt from a Company in Japan
Updated 2026-10-24
To collect from a Japanese company, rely first on a Japanese-speaking partner who confirms the company in the commercial registry, sends a formal demand in Japanese and negotiates politely but firmly with the finance or management team. Most collectible accounts settle at this stage. A U.S. judgment needs a Japanese court ruling to be enforced, with reciprocity and other conditions reviewed, so confirm legal options with Japanese counsel.

Collecting in Japan
Japanese companies generally place a high value on reliability and reputation, and many pay promptly once a clear, respectful demand reaches the right person. Problems usually come from disputes over quality or delivery, internal approval delays or genuine financial difficulty. A Japanese-speaking partner can tell which one you are dealing with far faster than an email chain in English.
Tone matters. Aggressive demands can backfire in Japan, while a formal letter that sets out the facts, the documents and a clear deadline is taken seriously. In some cases our partner may recommend a content-certified letter, a formal postal service that creates official proof of what was sent and when.
How a Japanese file runs
- Confirm the registered company name in Japanese, the corporate number and the representative director
- Check for bankruptcy, civil rehabilitation or other insolvency proceedings
- Send a formal demand in Japanese through an in-country partner
- Follow up by phone and email during Japanese business hours
- Negotiate payment or a written plan for your approval
- Prepare a legal recommendation with costs if the debtor will not pay
Legal options and U.S. judgments
If the debtor refuses to pay, a Japanese lawyer can bring a claim in the court with jurisdiction over the debtor. Japan also has a summary payment demand procedure for money claims and court-annexed conciliation, which can help in disputes where both sides want to preserve the relationship. Proceedings are conducted in Japanese, so documents need translation.
A U.S. judgment cannot be enforced in Japan until a Japanese court issues an execution judgment. Under the Code of Civil Procedure, the foreign judgment must be final, the foreign court must have had jurisdiction under Japanese standards, the defendant must have been properly served or have appeared, the judgment and proceedings must not conflict with Japanese public policy and there must be reciprocity with the foreign jurisdiction. Japanese courts have recognized judgments from some U.S. states, but reciprocity is assessed state by state, and punitive damages are not enforced. Service of the original U.S. lawsuit on a Japanese company is a frequent weak point, so Japanese counsel should review the file before you rely on the judgment.
Documents to prepare
- Signed contract or purchase order, ideally with the company seal of the Japanese entity
- Invoices showing currency and payment terms
- Shipping and delivery records, or proof of services
- Emails acknowledging the balance or confirming receipt of goods
- Japanese translations of key documents if legal action is likely
- Any U.S. judgment, with proof of how the Japanese company was served
Practical points for U.S. creditors
Japan is 13 or 14 hours ahead of U.S. Eastern time, depending on daylight saving in the U.S. Our partners work Japanese business hours and update your file overnight. Many Japanese companies pay on fixed monthly cycles, often at month end, so a settlement that lines up with the debtor's payment run tends to move faster than one that requires an exception.
Major holiday periods, including Golden Week in spring and the New Year period, can delay responses by a week or more. We plan follow-ups around them.
Frequently asked questions
Can I enforce a U.S. judgment in Japan?
Only after a Japanese court issues an execution judgment. The court checks finality, jurisdiction, proper service, public policy and reciprocity with the relevant U.S. state. Punitive damages are not enforced. Ask Japanese counsel before relying on it.
Should I write to my Japanese customer in Japanese?
For a formal demand, yes. Our partners prepare demands in Japanese, which avoids misunderstandings and shows the claim is serious. English is often fine for routine follow-up with international finance teams.
What does collection in Japan cost?
Amicable collection is billed on contingency, so you pay a percentage of what is recovered and nothing if nothing is recovered. Translation, legal fees and court costs only arise if the file escalates, and they are quoted to you in advance for approval.
What is a content-certified letter?
It is a Japanese postal service that certifies the content and delivery date of a letter. It provides formal proof that a demand was sent and is sometimes used before legal action.
