Plan a roots trip to Japan

Trace your Japanese roots through family registers and regional temples.

← All countries

Japan has a well-documented system of family records spanning centuries. Civil registration began in 1875 for births, marriages, and deaths, while earlier records were often kept by Buddhist temples and Shinto shrines. Many family historians find that Japanese records are more centralized and accessible than those of some other Asian countries, though local variations exist.

Genealogy highlights

  • Koseki (戸籍), the family register, is the primary record for births, marriages, deaths, and adoption since 1875.
  • Temple records (jiin) and shrine records (jinja) may contain earlier genealogical information, especially for Buddhist and Shinto families.
  • Pre-1875 samurai and merchant families sometimes have well-preserved clan records (keizu).
  • Local city and town offices hold original koseki and related documents; requests can often be made by mail or in person.
  • Census records exist but are less detailed than Western equivalents; some are held by prefectural archives.
  • Emigration records and passenger lists are available for those who left Japan during the Meiji and Taisho periods.

Record types to know

  • Koseki (family register)
  • Civil registration (births, marriages, deaths)
  • Temple and shrine records
  • Clan records (samurai and merchant families)
  • Local town office documents
  • Emigration and passenger records

Emigration patterns

Japan saw significant emigration from the 1880s to the 1940s, particularly to Hawaii, the United States, Canada, Brazil, and Peru. Many emigrants were recruited as agricultural or contract laborers. Records of departure are held by prefectural offices and the National Diet Library; receiving countries' immigration archives may also document arrival.

Heritage trip tips

  • Plan visits to your ancestor's hometown (furusato) office to request koseki and related records in person; staff often speak some English in larger cities.
  • Visit family temples or shrines if known; monks and priests may provide access to genealogical records kept in their archives.
  • Spring and autumn offer pleasant weather; winter can be snowy in northern regions, and summer is hot and humid.
  • Learn basic Japanese phrases or use translation apps when visiting local offices; smaller towns may have limited English speakers.
  • Respect local customs when entering temples and shrines: remove shoes where indicated and dress modestly.
  • Consider hiring a local genealogy researcher if records are scattered across multiple prefectures or if language is a barrier.

Practical notes

  • Koseki requests are typically made to the ward office (ku-yakusho) or town office (machi-yakusho) of the place of registration. You will need to provide the person's name, approximate date, and relationship to you.
  • Records older than about 80 years may be archived at prefectural archives rather than local offices.
  • Japan uses the Western calendar for modern records; older documents may use Japanese era names (nengō).
  • Traveling between towns is straightforward via trains and buses; the Japan Rail Pass may offer value for multi-region trips.
  • Verify current entry requirements with your embassy or official government sources before planning your trip.
