Japanese-American Genealogy

By Alice Kane

List of Demands by the Voice of the Nisei, ca. 1944Introduction

The original immigrants to the United States, the issei, or first generation, intended to get rich in America and return to Japan. Mostly young men, issei endured hardships as temporary migrant workers, but tenaciously succeeded in acquiring farms and starting businesses in California and Hawaii. Issei women arrived in larger numbers after the 1907 "Gentlemen's Agreement" between the United States and Japan, many as picture brides to established issei men. Nisei, or second generation, are their children who grew up embracing American society and culture. The Sansei, or third generation, are the grandchildren of original immigrants from Japan.

Japanese American family history research can be conducted using standard genealogical resources such as censuses and city directories, as well as records documenting military service, probate, and land transactions. Laws from the 1920s prohibiting land ownership by Japanese make researching issei owners difficult as they made purchases under their children's names or as incorporated companies. Records related to the internment of Japanese Americans can be found in the NARA branch in San Bruno, California. Investigating local and state legislation for references to Japanese residents may yield record sources specific to Japanese in these jurisdictions.

Koseki are registers of Japanese families. Under Japanese law since 1872 (Meiji Restoration), all households are required to report births, deaths, marriages, divorces, adoptions, and acknowledgments of paternity of all Japanese citizens. These registries are located in the city/town halls, so knowing the hometown as well as the family name or household head is helpful in finding a koseki. Consulting the latest Japanese references detailing former and present place names, as well as addresses of the local government offices for those places, will be helpful.

Joseki are registers of family members withdrawn/removed from Koseki for reasons of death, marriage, or renouncing Japanese citizenship. Such registers are also kept in city/town halls where a particular person or family lived.

Kakocho are Buddhist death registers which record a person's name and death date, among other data. Such registers are kept in the Buddhist temples near where the deceased person lived. For more information about researching in Japan, visit FamilySearch.org.

This collection is not searchable by individual name. Images of titles held by the National Archives of Japan in Tokyo are organized first by the family surname and its kanji character(s), then the country/region/town described in the keizu. Genealogies published during the Edo period (1603–1867) have many errors and should be verified.

The major entry points into the United States for Japanese immigrants are Honolulu, Hawaii, and San Francisco, California. Ancestry.com has a large collection of databases containing passenger list images for these and other ports in the United States. Note: Occasionally Japanese passengers were confused with Chinese passengers and may be included in Chinese-specific immigration databases. Use "Chinese" in the keyword field of Ancestry's Card Catalog search to quickly bring up a list of these databases.
