What Is a Global Liaison Partner?

The Global Liaison Partner program is an official alliance initiative designed to help clients in your country connect securely with Tantei Hojin Chosashikai Inc. for their investigation needs within Japan, enabling you to expand your business opportunities.The program is open to law firms and attorneys, private investigation agencies, business consultants, and companies with established expatriate networks around the world.

As a partner, your role is to conduct initial consultations with your clients and refer their cases to our company. From that point onward, our company, Tantei Hojin Chosashikai Inc., will work directly with the client to provide all required explanations, execute the service agreement, conduct the investigation, and deliver the final evidence report, in full compliance with Japan’s Detective Business Act. Partners are not required to assume any legal or contractual responsibilities associated with the investigation. When a referred case results in a signed engagement, we will pay the partner a referral fee (incentive) in accordance with our established terms.

The Value of Our On-the-Ground Intelligence in Japan

Due to language barriers, cultural differences, and Japan’s strict personal information protection and privacy laws, it can be extremely difficult for overseas professionals to obtain information directly within Japan. Founded in 1998 and registered with the Tokyo Metropolitan Public Safety Commission (Notification No. 30200224), Tantei Hojin Chosashikai Inc. conducts investigations in full compliance with Japanese law, obtaining on-the-ground intelligence and real-world insights that cannot be obtained through online research (OSINT) alone.

We conduct nationwide surveillance, physical monitoring, and discreet inquiries into targets located in Japan, supporting a wide range of needs, including due diligence for corporate mergers and acquisitions, background checks on corporate executives, evidence gathering in international divorce and hidden-asset cases, and verification of fraudulent businesses. We deliver high-quality evidence reports suitable for use in overseas legal proceedings and business negotiations.

By serving as your local investigative partner and operational team in Japan, we help you address your clients’ challenges effectively and provide reliable, on-the-ground support for cases involving Japan.

Case Studies & Partner Testimonials

Here are representative examples of investigations conducted in Japan in collaboration with our global partners. By navigating language barriers and Japan’s complex legal requirements, including privacy protection laws, we help our partners deliver reliable evidence to their clients.

Case Study 1: Due Diligence for an M&A Transaction Between a Foreign and Japanese Company

A European client was considering a business partnership with a Japanese manufacturing company. However, financial statements alone could not reveal the company’s actual operating conditions or provide sufficient insight into the background and associations of its representative, including potential ties to organized crime.Our team conducted on-site verification and discreet inquiries to gather field intelligence. The investigation uncovered serious issues that the target company had not disclosed, including unpaid obligations and workplace environment problems. Through the referring consultant, the client was able to avoid substantial investment risks before proceeding with the transaction.

Case Study 2: Investigation into Hidden Assets and Actual Living Circumstances in Japan in Connection with an International Divorce

An individual involved in divorce proceedings in the United States was suspected of concealing assets in Japan while falsely claiming to have no income.At the request of the U.S. law firm, we conducted an investigation into the individual’s activities in Japan. We obtained compelling evidence, including photographs and activity records, showing that the individual was residing in a luxury property and operating a business in Japan. We then submitted an investigation report in English.The findings became a key factor in securing more favorable terms during negotiations in the U.S. divorce proceedings.
