Japan is the world's fourth-largest economy and a market built on long-term relationships, reputation and trust. Tokyo is one of the world's great financial and corporate centres, Osaka and the Kansai region anchor manufacturing and trade, Nagoya is the heart of Japan's automotive industry and Fukuoka is a growing gateway to Asia. Foreign companies entering Japan, acquiring Japanese businesses or partnering with Japanese firms need information that respects local norms and legal rules while answering hard questions honestly.

- Reputation and relationship risk in partners, distributors and acquisition targets, where problems are rarely visible from outside
- Accounting and subsidiary fraud in domestic and overseas operations of Japanese groups
- IP infringement, including counterfeits of Japanese brands abroad and copying of foreign products in Japan

- Formal and time-consuming legal service rules for foreign proceedings
Our Investigation Services in Japan
Due Diligence in Japan
Our due diligence in Japan covers acquisition targets, partners, distributors, suppliers and investors. We research commercial registration records held by the Legal Affairs Bureaus, court information, credit and business databases, and Japanese-language media, and conduct discreet enquiries within business networks to understand reputation and history. Findings are reported in English with key Japanese sources explained.
Anti-Social Forces Checks in Japan
An anti-social forces check in Japan screens companies and individuals for links to organised crime groups and associated businesses. Many Japanese contracts require parties to warrant that they have no such links, and financial institutions, real estate firms and listed companies are expected to verify this. Our checks combine specialist database research, media review and discreet enquiries, and are documented for your compliance file.
Corporate Investigation in Japan
Our corporate investigation in Tokyo and across Japan covers fraud, embezzlement, accounting irregularities, conflicts of interest and employee misconduct, including investigations into overseas subsidiaries of Japanese groups. We work with your legal team within Japanese labour and privacy rules.
Background Check in Japan
Our background check in Japan services verify identity, education, employment history, directorships and litigation for executives, managers and business partners, with consent and in line with Japan's Act on the Protection of Personal Information (APPI).
IP Investigation in Japan
Our IP investigation in Japan covers trademark infringement, design and patent infringement, copied products and trade secret misuse. For Japanese brand owners, we investigate counterfeits of their products abroad, from Asia to the Middle East and Africa.
Brand Protection in Japan
We monitor Japanese marketplaces, auction sites and social commerce for counterfeit and grey market goods, carry out test purchases and trace products to importers and sellers, supporting customs and legal action.
Claim Investigation in Japan
We verify property, cargo, marine, motor, life, health and travel claims with a Japanese element, including incidents involving travellers and international shipments.
Process Service in Japan
Japan is a party to the Hague Service Convention but has objected to the alternative methods of service under Article 10, including service by post. In practice, service of foreign judicial documents on parties in Japan is carried out through the Japanese Central Authority, with Japanese translations required, and can take several months. Our process service in Japan team prepares requests, arranges translations and tracks progress, and advises on planning timelines around this route.
Private Investigation in Japan
For businesses and law firms, our business-focused private investigator in Japan services include witness location, debtor tracing, asset searches, litigation support and lawful commercial enquiries. Investigation businesses in Japan operate under specific regulation, and all work follows that framework. We do not accept personal or matrimonial cases.

Understanding Reputation in Japan
In Japan, problems with a company or individual are rarely publicised. Disputes are settled quietly, relationships end without explanation and concerns circulate within industries rather than in the press. For foreign companies, this makes desk research alone insufficient. Our investigators combine records with careful, respectful enquiries among business contacts, former partners and industry sources, giving you a realistic picture of a counterparty's standing without causing embarrassment or damaging relationships.
Investigating Overseas Subsidiaries of Japanese Groups
Japanese companies operate extensive networks of subsidiaries across Asia, the Middle East, Africa and beyond. Distance, language and cultural differences can allow fraud or misconduct to develop unnoticed. Headquartered in Dubai with a network in more than 100 countries, we investigate subsidiaries, distributors and joint ventures abroad on behalf of Japanese head offices, reporting in English and coordinating with Japanese-speaking stakeholders.
