'Luffy' group-directed robberies (2023)
A group of suspects based in the Philippines used encrypted messaging to direct a wave of robberies and scams inside Japan, and some of those robberies ended in deaths. Commands were readable only on the phones of the people involved, so police could not see plans early enough to intervene.
Ringleaders operating from abroad avoided detection, and Japanese police could not read instructions in time to stop the crimes.
The cases became the backdrop for the remote-analysis proposal, which the NPA expert panel studied from August 2026.
The Luffy case showed why encrypted apps defeat traditional surveillance; this bill is Japan's direct legislative response.
