For Those Requesting Investigations in Japan from Overseas | TSK INTERNATIONAL, Covering All of Japan

Investigations in Japan You Can Request from Overseas

Even if you live overseas, an investigation within Japan can be considered as long as the person or company you wish to investigate is in Japan. We do not classify investigations by the subject's nationality alone; instead, we organize who needs to be investigated, where, and what needs to be confirmed.

Person Search, Whereabouts and Safety Checks

This covers cases such as being unable to reach a family member or relative in Japan, wanting to learn what became of a former acquaintance, or wanting to confirm whether a known address is still valid. We consider verification methods based on leads such as when you last had contact, the person's name, photographs, and former addresses or workplaces. Confirming someone's whereabouts is treated as a separate matter from whether that person wishes to be contacted or reunited.

Infidelity, Conduct and Living Situation Checks

This investigation looks into a spouse's activities in Japan, their daily life during a business trip or posting in Japan, and discrepancies between what you were told and their actual schedule. We organize their place of stay, work schedule, and the dates you wish to check, and consider the range of activities that can be lawfully verified in Japan. We do not conclude the nature of a relationship from a single meeting or meal.

Background Checks on a Partner or Fiancé(e)

This applies when there are specific uncertainties about the name, workplace, or personal background that a partner living in Japan has described. We compare the information provided by the person with obtainable materials and verifiable facts. Without prejudging by nationality or place of origin, we narrow down the points that need to be confirmed for your decision about marriage or the relationship.

Verifying Japanese Companies and Business Partners

This is a check of company information, location, business operations, and the consistency of provided materials, for those considering transactions or partnerships with Japanese companies from overseas. Please gather the company name in Japanese, its address, website, and any quotations or contract documents. Non-public financial or internal company information cannot be obtained unconditionally.

Even if several issues overlap, you do not need to decide on the type of investigation from the start.Investigation Services also lists our investigations overseas. For cases within Japan, we use this page as the starting point and organize the details according to your purpose and the target area.

Investigations Across All of Japan

You can consult us about investigations anywhere in Japan, not just Tokyo. The plan will vary depending on the target area, the range of travel, the information you have, and the work required. Nationwide coverage does not mean the same fees or schedule apply in every region. After confirming the target area, we will explain the specific approach.

If you only know an address in Roman letters, or only a former address, please tell us as it is. Organizing the prefecture, city or ward, building name, and when you obtained the information helps avoid confusing people with the same name or similar place names. There is no need to fill in unknown details with guesses.

Our Operator and Cooperation with Attorneys

Operated by Tokyo General Detective Agency, Founded in 2000

TSK INTERNATIONAL is operated by Tokyo General Detective Agency. We also accept inquiries from clients living overseas about fact-finding and whereabouts or activity investigations within Japan. When requesting an investigation from a distance, it is important to confirm not only the name of the contact point but also the actual operator and the contract terms.

When Legal Action Is Needed After an Investigation

Our operator, Tokyo General Detective Agency, has partnered with attorneys as legal advisors. In addition, there is a law office adjacent to our office, and we are able to consider handing over cases to, or cooperating with, an attorney as needed. For divorce, financial disputes, business issues and similar matters, we organize the case together with how the investigation results will be used.

The detective agency handles fact-finding and evidence collection, while individual legal judgments, negotiations with the other party, and litigation are handled by attorneys. Whether an attorney can accept a case, how to consult, supported languages, and fees must be confirmed individually. An investigation contract does not necessarily include legal consultation or litigation fees.

If you are already consulting an attorney in your country of residence or in Japan, please tell us how the investigation results will be used and what materials are required. How records collected in Japan will be evaluated in proceedings overseas must be confirmed with a specialist who handles those proceedings. For details, please see our operator's information on attorney cooperation and legal advisors.

What to Tell Us in Your First Consultation

You can consult us even if you do not have all the Japanese documents or exact addresses. Please start by organizing the information you have and what you want to know.

• Your situation: Your country or region of residence, your relationship to the subject, and your reason for requesting an investigation.
• Where to investigate: Addresses in Japan, workplace, place of stay, and the area where the person was last confirmed. Whatever you know is fine.
• Information to identify the subject: Name in kanji, kana and Roman letters, recent photographs, company name, contact details, and so on.
• Background so far: The date you last made contact, any inconsistencies in what you were told, checks you have already made, and when you obtained any materials.
• Desired outcome:Confirming whereabouts or living circumstances, preparing for discussions, or gathering material for a consultation with a lawyer.
• Contact preferences:Your preferred language, times when you can be reached, your own time zone, and any contact details or methods that should be avoided.

If you have organized your information in English, Korean, Chinese or another language, please also keep the original spelling of names and addresses. Before the contract is signed, we will confirm how you will communicate with your representative, which documents need translation, and the language of the report. The fact that the website has pages in several languages does not mean that every document or every representative can be handled in the same languages.

Online contracts with no need to travel to Japan

For requests from overseas, the entire process up to signing the contract can be completed online. This reduces the burden of traveling to Japan or arranging in-person meetings, and allows procedures to move forward quickly. After you have reviewed the investigation details, fees and contract terms and are satisfied with them, we will proceed with the necessary documents and the procedures to start the investigation.

Private investigation in Japan is subject to rules, including explaining the contract and providing it in writing, and confirming that investigation results will not be used for unlawful purposes. Even when handled online, necessary confirmations are not skipped. If there are terms or conditions you do not understand, please ask us rather than leaving them unresolved.

Before the contract is signed, we will confirm the area, period and methods of the investigation, the content of the report, conditions for additional costs, and how changes or cancellations are handled. Please also confirm in advance the payment method, currency, and who bears remittance fees. Even when the procedures can be completed in a short time, we do not guarantee that an investigation will start on the same day in every case.

What can be confirmed, and the limits of an investigation

Investigations within Japan are carried out in accordance with Japanese law and with consideration for the rights and daily lives of the people concerned. Detectives and private investigation agencies do not have the same authority as the police, and cannot enter residences, obtain the content of communications without permission, or acquire personal information unlawfully.

For person searches, we confirm the purpose of the request and your relationship with the subject. We cannot accept requests that could lead to stalking, unlawful discrimination or similar conduct. The safety and wishes of the individual must be respected, and even if their whereabouts are found, it does not necessarily mean their address will be disclosed or that a reunion will be possible.

In our reports, we distinguish between facts that have been confirmed and points that remain unconfirmed. An investigation contract alone does not promise that the desired information will be obtained, that the subject will be found, that a refund will be obtained, that a relationship will be repaired, or any outcome in court.

How costs and timeframes are determined

Even for requests made from overseas to Japan, we provide an individual quote tailored to the investigation. Confirming a location and conducting behavioral surveillance over several days require different work. We plan the investigation based on factors such as the area, the accuracy of the prior information, travel distance, number of personnel, working hours, and whether records need to be obtained or translated.

• The scope of investigation included in the basic fee, and expenses such as transportation, accommodation and the cost of obtaining records.
• How additional investigation is approved when needed, and the budget ceiling.
• Fees applicable if the subject cannot be located or the desired information cannot be obtained.
• The report delivery date, any necessary translation, and the fee categories if you are considering consulting a lawyer.

Fees and the Application Processas well. The reference fees for overseas investigations on that page do not apply as they are to cases within Japan. We will provide guidance on costs and timeframes depending on which area of Japan and what needs to be confirmed.
