Official sources
Start with the 日本 authorities closest to the question.
Agency pages and official portals are more useful than unsourced summaries, but they still need a date, a precise question, and an applicability check.
How the research is used
AI can compare material; it cannot approve the conclusion.
Faith Forge Labs uses research and AI to find terminology, conflicts, edge cases, and follow-up questions. Logan reviews the technical implications. The client or a qualified adviser owns legal, tax, accounting, sanctions, export-control, and regulated-industry conclusions.
- Record the date and exact question behind each source
- Separate official guidance from vendor documentation and commentary
- Check whether the material applies to the client, user, and service
- Recheck important assumptions before launch
- Assign an owner to monitor changes after handoff
Next step
Turn the 日本 context into a workable brief.
Before a stack or schedule is chosen, identify who will use the system in 日本, who owns each decision, and which assumptions still need local confirmation.
