Marriage is supposed to be the process of two people making their relationship official and permanent, but it is often cut short by separation or divorce. Common sources of marital stress and marriage problems are bad habits, time, issues with children, money problems, infidelity, etc.


Regardless of how long you’ve been together, there might come a time when a matrimonial disagreement arises.


Doubt when unresolved might lead to suspicion over time. Without proof, the suspicion is just a belief. When you start to see a pattern of behavior that might indicate a lack of trust, and you don’t have enough proof to make a firm conclusion. You will continue to think that there is something wrong. We are here to help you reveal information that you need to put facts into your suspicions and to resolve marital issues.

Japan`s divorce rate has been growing and extramarital affairs have become one of the main causes of the problems. When filing for a divorce on grounds of adultery, you will have to provide proof before the court will consider it. You will need documentation that you can use in the trial.  We will find other activities of your spouse that might prove grounds for divorce. We can obtain proof for you that will not only give you peace of mind. But also with a quality report with evidence that is legally court-admissible.


Child custody is a difficult and sensitive issue that comes up during divorce, separation, or custody case. In western countries, joint custody after divorce is allowed. However, in Japan, a married couple has joint custody, but in the case of a divorce, the couple must decide who will get the custody. If you can’t agree on parental authority, the court will decide.


We have carried out a large number of child custody investigation cases nationally and internationally. Our team can help you gather information and evidence to help you win your case.
