Tokyo is considered a safe city for tourists. The crime rate is relatively low, and locals are known for their honesty and helpfulness. We felt extremely safe while we were there, even on crowded subways. It felt safe enough to allow our teenage daughter to explore a bit on her own. However, it is always advisable to take standard precautions, such as keeping an eye on your belongings, especially in crowded areas. In case of emergencies or if you need assistance, look for police boxes (koban) or ask for help from station staff or hotel personnel. Additionally, it is required to carry your Passport with you when traveling in Japan.
