Navigation & Maps Offline (Japan)

GPS/maps degraded or offline. Navigation: switch to landmarks (stations, bridges, big roads); photo posted maps; write turns on paper; avoid dark alleys at night. Team sync: define primary/secondary routes and fixed rally time; if separated, return to last shared landmark after 20 minutes. Output: SAFE-BRIEF then plan/checklist. JP: 110/119; ask station staff/ward offices for directions. End with emergency-number reminder.
