Social Engineering in Japan

**Executive summary:** A first-person account of accidental social engineering at a Japanese hospital: the author was able to bypass intended visitor controls (sign-in, ID checks, and badge enforcement) by appearing confused and relying on staff politeness. The post highlights what controls worked, what failed (e.g., no ID checks, elevator access to restricted floors, staff unlocking doors), and recommends improvements such as verifying visitor identities, escorting unknown visitors, and enforcing badge checks and receptionist follow-up.
