The Child Custody Disadvantage
For most mothers, the biggest fear in a divorce is losing their children. In Japan, this is a very real risk.

- No Joint Custody: Japan’s system grants sole custody to one parent. This means one parent wins, and one will lose access to their children.
- Possession is Key: The parent who has the children at the time of separation often wins custody. This can lead to a situation where one parent suddenly takes the children to gain an advantage.
How we help: If you have been separated from your children, you cannot take any legal action until you know where they are. Our investigators specialize in finding separated children in Japan. We can quickly and discreetly locate them and provide you with a confirmed address and a wellness check on their living situation. This is the essential first step.
The Visa and Residency Disadvantage
For a foreign wife, living in Japan is often tied to her marriage. A divorce can put your entire life in the country at risk.

- Your Spousal Visa Ends: After your divorce, your “Spouse of a Japanese National” visa is no longer valid. You will have to apply for a new visa to stay in the country, which is not guaranteed.
- A Tool for Control: This visa uncertainty can be used as a threat in a divorce. Your husband might say you will be forced to leave Japan without your children if you don’t agree to his demands.
The Financial Disadvantage (Alimony)

Getting fair financial support can be a major battle, especially if you have been financially dependent on your husband.
- Alimony is Only for “Fault”: As we explain in our guide to alimony in Japan, you can only get “consolation money” (isha-ryo) if you can legally prove your husband’s actions (like cheating) caused the divorce.
- Proof is Required: Without solid evidence, you are not entitled to any compensation for your emotional suffering.
How we help: Our primary role in a divorce case is to get you the proof you need for a fair financial settlement. Our professional infidelity investigation service is designed to gather the exact kind of clear, undeniable evidence (photos and videos) that your lawyer can use to build a strong case for alimony.
Our Role: How Our Investigation Services Can Help You
When you are facing these disadvantages, an investigation is your most powerful tool to level the playing field. Our job is to get you the factual evidence you need to support your legal case.

Here are the direct ways we help:
- We Find Your Children: If you are separated from your children, our immediate priority is to locate them. We provide you with their current address and can conduct a wellness check to ensure they are safe. This is the crucial first step before your lawyer can act.
- We Gather Evidence for Alimony: If your husband’s infidelity caused the divorce, we will get you the proof. Our discreet surveillance provides the hard evidence (photos/videos of him with the other person) that you need to claim the financial compensation you deserve.
- We Search for Hidden Assets: During a divorce, one spouse might try to hide money or property to avoid splitting it fairly. We can conduct a search for hidden assets, such as secret bank accounts or properties, to ensure a fair division of assets.
Our work provides your lawyer with the factual ammunition they need to fight for your rights.
