The old PI registration certificate was abolished: checking the 2026 “marker” (標識)

Japan changed the public display system in April 2024, so old advice to ask for a registration certificate is out of date.

What changed

From April 1, 2024, the prefectural commission’s detective-business notification certificate was abolished. Operators now prepare a marker and display it prominently at the office; subject to stated exceptions, it must also appear on the agency website.

What to look for online

  • Office name
  • Office address
  • Public Safety Commission
  • Notification filing date
  • Notification number
  • Individual or corporate operator name

A marker is only a starting point

It does not guarantee quality or results. Also review the quote, important-matters explanation, contract, complaint route, and data handling.
