Japan, an island nation located in East Asia, is composed of four major islands: Kyushu, Honshu, Hokkaido, and Shikoku. From military strength and economic power to cultural influence, Japan remains one of the leading nations in the modern world.
When people think of Japanese society, they often associate it with discipline, order, and a polite, reserved demeanor. However, behind this social façade, the stress of maintaining such cultural expectations can lead to sudden emotional outbursts, which in turn may cause serious social or personal issues.
Many of these problems stem from family conflicts, marital breakdowns, or cutthroat competition in the corporate world. In Japan’s modern, highly urbanized society, human relationships have become increasingly complex, making it difficult for individuals to uncover the truth on their own.
As a professional private investigation agency, Yitong has extensive experience in handling both personal and corporate investigations. Our familiarity with interpersonal dynamics and corporate rivalries enables us to efficiently address a wide range of cases. Over the years, we have collaborated with numerous Japanese detective agencies to resolve cross-border marital infidelity cases as well as corporate espionage disputes, offering clients comprehensive and prompt solutions through seamless cooperation between Taiwanese and Japanese experts.

Are detective agencies the same as credit investigation agencies?
When we think of detectives and detective agencies in Japan, the first images that come to mind might be the exciting scenes from manga like "Detective Conan" or Japanese dramas, where detectives work closely with the police to solve cases. However, in reality, the role of a detective agency in Japan is quite different from that of the Japanese police, and the cooperation between the two is limited. The strong association with police collaboration in popular media comes largely from the influence of Western detective novels, which have shaped these perceptions.
So, what exactly do Japanese detective agencies do? We can get a sense from Japan's "Private Detective Business Act." This law clearly defines the scope of the detective industry, including various investigations, surveillance, and tracking, and specifies who is prohibited from engaging in detective work. The most important point is that all related activities must be carried out legally and cannot involve illegal means to obtain information.
From the information provided, we can see that private detectives and detective agencies in Japan focus mainly on handling marital disputes, such as infidelity investigations, and tracking people. Other common tasks include corporate espionage and employee investigations. Unlike Taiwan, Japan's thriving adult entertainment industry and the prevalence of "hostess bars" mean that private detectives often have to work in such establishments. Surveillance, wiretapping, and counter-surveillance are also part of their common activities.
Looking at this, do Japanese detective agencies resemble Taiwan's credit investigation agencies? The biggest difference is that Taiwan lacks a specific law to regulate the entire credit investigation industry, resulting in a wide disparity in professionalism and fee transparency. On the other hand, Japanese detective agencies have developed significant expertise and case-handling skills, offering many practices that Taiwan's credit investigation industry could emulate. At Yitong Credit Investigation, we continue to strengthen our team's capabilities and techniques, and we believe we can provide professional services and solutions similar to those of Japanese detective agencies.

Investigation Fees of Japanese Credit Investigation Agencies
With the rapid development of private detective agencies, the competition among Japanese detective and credit investigation agencies is understandably fierce. Depending on the region and type of case, the prices can vary significantly. For simple surveillance and investigation tasks, the cost can range from 4,000 to 10,000 yen per hour, depending on factors such as the number of personnel, location, and duration. Some agencies with more advanced equipment and technology may charge even higher rates. Additionally, for more complex cases such as corporate investigations or missing person searches, the fees are generally much higher due to the more involved procedures.

Should you choose a Taiwanese credit investigation agency or a Japanese detective agency?
Additionally, many people might wonder, since the differences between detective agencies and credit investigation agencies are not that significant, how should one choose between the two? If it’s a case in Taiwan, of course, you should choose the best agency, Yitong Credit Investigation Agency. Not only does it have a professional and effective team, but its equipment and investigation methods are on par with those of Japanese detective agencies. But what if the case is in Japan? It would still be best to choose a Taiwanese credit investigation agency to handle the case. The main reasons can be broken down into three aspects:
- First, Yitong Credit Investigation Agency has over forty years of experience in the field, and has long had close cooperation with local Japanese detective agencies. The issues of language barriers, geographical relationships, and cultural differences can essentially be resolved through Yitong’s professional services.
- Additionally, if you have legal questions or other issues that require urgent answers or assistance, the services provided by a local Taiwanese credit investigation agency can offer immediate solutions, saving you the time and effort of communicating with a Japanese detective agency.
- By entrusting your case to Yitong Credit Investigation Agency, our professionals will ensure that your case is handled to the highest standard according to your needs.
