Message from Representative

Modern society faces many corporate risks associated with sudden changes in economic structure, diversification, and sophistication.

In our daily lives, too, we often come face to face with risks that threaten our peace of mine, and whether we like it or not, our lives are filled with the danger that we may find ourselves caught up in trouble.

We believe that proactively obtaining appropriate information on a day-to-day basis, making decisions based on such information, and contributing to action is extremely important to forestall such problems.

Accurate and sophisticated information is necessary when forced to decide on the direction we should choose as a company, and when objective assessments and decisions on specific corporations or individuals are required.

In reality, our complicated society and organizations are causing friction in human relationships, leading to trouble arising from various interests.

In such situations, corporations often find it difficult to reach a solution on their own. The same applies to individuals.

In general, the reality is that, people who face worries can become fragile mentally and are unable to find the clues for solving issues on their own.

We offer a broad range of investigative services, including investigations into people and corporate credit checks, diversified investigations concerning corporate crisis management, M&A related investigations, intellectual property checks, asset (property) checks associated with debt collection, behavior (shadowing) investigations, traffic accident investigations, and private investigations such as the collection of evidence necessary for lawsuits resulting from extramarital affairs and adultery.

Through WAD (the World Association of Detectives), established in the USA in 1925, we use our extensive network of individuals in more than 70 countries, spanning the US, Europe, China, Taiwan, South Korea, and Southeast Asian countries, as well as state-of-the-art IT, and more to provide support for companies operating overseas such as conducting checks on foreign corporations, checks on specific individuals, foreigner recruitment investigations, location surveys, missing person investigations, behavior (surveillance, shadowing) investigations, security situation investigations, asset (property) checks, and finance-related checks concerning money laundering.

Our utmost priority is accurately solving issues facing our clients, thereby satisfying our clients.

We work day and night, striving to be the best partner our clients could ask for.
