Japan is one of the safest countries in the world for travelers. Violent crime is extremely rare, lost wallets are regularly returned, and public spaces are immaculately clean. Solo travelers — including women — report feeling very safe throughout the country.
Natural hazards are the main concern: Japan sits on the Pacific Ring of Fire and experiences earthquakes and typhoons. Register with your embassy and follow local emergency alerts. Familiarize yourself with evacuation routes in your accommodation.
