Safety and Disaster Preparedness in Gaiemmae

Kita-Aoyama 1-3 chome and Minami-Aoyama 1-7 chome around Gaiemmae fall within the jurisdiction of the Metropolitan Police Department's Akasaka Police Station. Because commercial streets, offices, residences and major sports venues coexist here, safety should not be judged solely by the neighborhood's general image. Police crime information and the actual nighttime environment around a specific address should also be checked. Large sports and entertainment events can sharply increase pedestrian volumes, making crowding and pedestrian-cyclist conflicts additional considerations. Minato City publishes hazard maps covering flooding, stormwater inundation, tsunami, storm surge, liquefaction, earthquake shaking and landslide risks. Conditions can differ even within the same station catchment, so checks should be made for the exact property address. Minato updated its flood and stormwater hazard information in July 2026. Residents and businesses should also review the latest Akasaka-Aoyama disaster-preparedness map for evacuation locations and emergency procedures.
