Welcome to our website!  The purpose of this website is to assist individuals who are researching their Japanese family history.

One of the key challenges in obtaining historical information about Japanese family members is knowing where to send requests for information.

Our MyKoseki website can help identify the appropriate local governmental office to which requests for copies of family registers should be sent.

Also included on this website are maps of Japan, showing the various prefectures, and some helpful links to other sources of Japanese family history research.

We invite your comments and suggestions on how to make MyKoseki an even better resource for Japanese family history research.
