Japan has maintained detailed family registers since the Meiji era (1868). Each koseki records births, deaths, marriages, addresses, and family relationships — often across 3–5 generations. These records are held by local municipal offices and are only accessible by family members or authorized representatives.
We access these records on your behalf and translate all findings into English.
All plans include a free initial consultation. Prices are in Japanese yen (tax included). International cards accepted via Stripe. Installment payment available.
Consultations and reports are available in the following languages. You do not need to speak Japanese at any stage of the process.
We typically reach the Meiji era (1868 onward). With well-preserved local records, some families can trace back to the Edo period (pre-1868). We'll give you an honest assessment during the free consultation.
