In no other city I’ve lived in have I felt so safe I took long night walks alone without a single worry. I have never been harassed or felt in greater danger. The only thing is, in the evening hours when the public transport is packed with people, that there could be potential for sexual harassment, but it never happened to me and during the very busy hours there special trains only for only women and elderly, so you can feel safe

It is extremely safe. Unless you go to cheap clubs, then it becomes quite unsafe so it is better to avoid such places. The most happening place for the nightlight is Susukino but I have walked alone in Susukino after midnight and never felt unsafe.
