What exactly do you need from Japanese genealogists?

Urgent Question for International Genealogists: What exactly do you need from Japanese genealogists?

I’m genuinely struggling to understand what probate genealogists need from me.

Here’s my problem:

The probate genealogy profession doesn’t exist in Japan. When probate genealogists contact me asking for “assistance” with Japanese cases, I honestly have no idea what they’re asking for. They use vague terms like “assist” or “collaborate,” assuming we share common understanding – but we don’t. When I ask for details, they often don’t respond.

Why I’m confused:

Japan’s koseki (family register) system works completely differently from what you’re familiar with:

  • Koseki is a comprehensive official certificate of family relationships – it’s the ONLY document needed to establish inheritance rights in Japan
  • Any heir can quickly obtain koseki for all family members
  • Once you have koseki, you know all heirs and their addresses
  • Therefore, “heir search” as a separate professional service doesn’t exist in Japan

About searching individuals in Japan:

The koseki system is effectively a nationwide individual database, BUT accessing it requires:

  • Full name in kanji characters
  • Date of birth
  • Honsekichi (registered domicile)
  • Applicant’s identification documents
  • AND applicant must be the person listed, direct relative, or heir

There is NO other nationwide searchable database for individuals in Japan besides the koseki system.

What I desperately need to know:

When you say you need “assistance” with Japanese cases, what SPECIFICALLY are you asking for?

  1. You have an old address but need current location?
  2. You have romaji names without kanji?
  3. Decedent is non-Japanese so no koseki access?
  4. Something else entirely that I’m not understanding?

Please, I’m asking seriously:

If you work with Japanese cases or have tried to work with Japanese genealogists, what specific obstacles are you facing? What do you actually need done?

I genuinely want to help, but I can’t figure out what help is needed because our systems are so fundamentally different.

Your concrete examples would be invaluable.
