Safety Information for Japan
Crime levels are low. It is generally safe to walk about at night and to travel on public transport, but you should maintain the same level of vigilance as you would at home and take sensible precautions. Reports of inappropriate touching or ‘chikan’ of female passengers on commuter trains are fairly common. The police advise that you shout at the perpetrator to attract attention and ask a fellow passenger to call the train staff. The Roppongi entertainment district of Tokyo is considered a higher risk area for crime.
