Yes, Japan is quite safe, but definitely not 100% safe. I also lived in Singapore and worked with some Japanese women in Singapore.

They told me that they felt 100% safe in Singapore, but, when home in Japan, they sometimes felt as if they were not totally safe. Several of them said that, and they each said that there was a distinct and noticeable difference.

Nevertheless, it's true that Japan remains one of the safest countries in the world, for both residents and tourists.

And, I hope the situation improves in Turkey. Good luck!
