1, Our Services (Investigation )

Cheating Husbands or Wives

From a very long time ago to the present, cheating husbands and wives have existed.
Your husband or wife could perhaps have an affair with someone you never knew or may possibly know. If something is different with your partner’s behavior, like coming home late at night, reluctant to answer the phone or never replies to E-mails, stays nights over somewhere else making excuses, you have the right to know the truth.

Missing Person

We have regularly appeared on the Japanese TV show “ I Want to See you ” searching for missing persons.
There are many reasons why people go missing and they suffer from all sorts of trouble.
Some call us the “Humane Detective” because we have dedicated ourselves to finding them out.

Fiances or Fiancees

Marriage is one of the most important events in our lives. Therefore, you should know and understand your partner thoroughly before getting married, such as former relationships, behavior in daily life and financial conditions.

Hidden Bugging Devices and Cameras

The number of victims who are secretly recorded by bugging devices or taken footages by hidden cameras are increasing each year. Anyone could be the victim, not only women or companies. You could hardly recognize or ever find those devices because they are micro-sized which are barely visible to human. We recommend you to let us investigate if there are any doubts about the existence of these horrible devices.

Stalker SNS Trouble and Harassment

Social Networking Service (SNS) has spread and is expanding all over the world which is changing the variation of stalkers. It is so exceptionally difficult to cope alone with evil stalkers annoying you by continuously calling, sending e-mails and posting SNS messages time after time. Anyone could become a stalker these days, even someone you have never even seen.
People coping with such problems should consult with us. Let us help collect evidence and drive away those stalkers with you.

Corporations on Employment Survey

Employing excellent people is one of the keys to advance in the global economy.
And it is important to monitor employees to be certain they are not engaging in dishonest acts, such as disclosing confidential information or skipping work. Let us investigate your staff-to-be and cooperate with you in prospective-employee survey.

Notice !

These days, the number of international divorces is on the rise along with international marriages.
When couples consider divorcing, most of them of any nationality would seek possessing child – custody.
In these cases, child abduction by a parent is one of the most serious issues. One parent may keep the child from the other parent and return to his / her country. Because he / she would want to gain advantage in child-custody proceeding. Of course, this is a wrongful action.
There is a multilateral treaty called “ The Hague Abduction Convention ” which provides a prompt method to return abducted children to the countries they have lived in. This only applies to the participating countries and Japan concluded the agreement in 2014.
If your child has been abducted and you want to possess child-custody, we would be happy to help you.
We can capture disadvantages of your spouse in a trial such as “ having affairs ”, “ child abuse or child neglect ”.
