Japan PI Services to Find Heirs or Lost Family

How to Locate Long Lost Family or Relatives

Note: If you are searching for person in Japan who is not a relative, visit our Find Missing Persons page.

It’s never too late to find resolution in locating a lost family member. Often situations beyond our control such as a divorce, move, adoption or other circumstances can cause us to lose contact with the ones with love.

In Japan, the difficulty can be exacerbated by a lack of public records; it is very challenging to search for someone in a phonebook, for example. If a client is able to provide us with his or her loved one’s Koseki records, family members become easier to track.

What are Koseki Records?

Koseki is the Japanese Citizen Registration System; an official document that every Japanese citizen possesses. All birth, death, marriage and divorce information is held within a single record.

How Do I Access to Koseki Records?
Three types of people have rights to access Koseki Records:

  • A direct bloodline next of kin
  • Attorneys and legal professionals

The Information you will need to access Koseki Records:

  • Honseki (permanent address) which is usually registered as the individual’s birthplace
  • The name of the head of the family


How We Can Help

Japan PI can contact the Japanese municipal for you to help obtain the Koseki records. If possible, please provide any of the following information:

  • Individual’s Japanese name and date of birth
  • Prior Koseki records
  • Prior address or district of address in Japan

If this information cannot be provided, our team, in collaboration with legal advisors and additional sources, can obtain Koseki records. Our group of international contacts allows us to trace family members even if they are no longer in Japan.

Japan PI is one of the few organizations in the country that offer these kinds of location services. Our team of bilingual private investigators allows for smooth communication with international families and our direct approach ensure no times is
wasted in reuniting our clients with their loved ones.

Sample Locate Family in Japan

I want to thank you so much for all the work you did on my case. I’m in Tokyo now and have been here since Monday. Since we were able to conduct this search before I arrived I was able to save time while here. Yesterday, I decided to approach Kenji’s house. He gladly accepted me into his home and we both were so happy to learn about each other and our past. We now have the opportunity to build a friendship because of you. Your work brought about a success on many levels.

So it all ends well. We’ve been reunited after 40 years of wondering. We now have a chance to discover each other’s personal preferences thanks to you.

FAQs on locating Family

Can you contact the Japanese family member for us?

Yes. Our concept is the fusion of PI services and translation. After locating the family member, we can contact them for the client.

We specialize in translation and proxy service for American clients. The majority of Japanese citizens are allergic to the contact from the foreign country even though it’s regarding their family members. Especially, if they receive a legal document on the probate matters from a foreign country, they will be frightened and all they will do is just neglecting it and wait for the sender to give it up.

Also, they tend to wonder if they may be responsible for the debts as well if they inherit something. Maybe Japanese ordinary lawyers or accountants will advise that you should be careful about the debts in the inheritance. And they don’t know how to ask questions in English. That’s the reason why they don’t respond at all.
