15. Tokyo, Japan
Japan’s transit system also fared well in the survey. Public transportation is the fastest and most convenient way to travel in Japan’s capital city. The transport system consists mainly of an above-ground train network, 13 subway lines and a nexus of flat-rate buses. Tokyo’s public transportation system ranks high in safety because the city recently implemented certain measures to try and prevent groping of women on board crowded buses and trains. Undercover policemen have been deployed, and stiff fines/prison terms are given to perpetrators. Tokyo was also the first in the world to create women-only train cars.
