Corporate behavior

 

new acts to new age

As developing technology, information is easily approachable by anyone in various situations. As a result, private information becomes highly sensitive and protected. On the other hand, in business fields or many other scenes, detective agencies are required to gather and make it one of the factors for our clients to make a decision. Through individual access to privacy getting difficult as technology develops, we believe that it is our mission to construct networks and adjust the way to approach.   

 

 

For reliability

At detective agency, we describe our fee system, set up payment system properly, and qualified service plan for our clients’ reliability. In case we find any errors or malicious activities, we will deal with the Public safety commision.

これから探偵事務所や興信所を利用しようとお考えの方は依頼する目的や必要な情報等を明確にしてから「相談」「委任契約」等を行うことをお勧めします。また探偵を利用するには費用が掛かります。自身が納得のいく料金で依頼することが重要です。探偵調査は目的によって正しく利用すれば後にとても役立つ情報を得ることができるので、依頼先と十分な打ち合わせの上、質の良い依頼をするよう心がけることが大切です。
