There are a lot of places around the world where it just doesn’t feel right to be out on the streets after sunset. You probably know some of those places. Japan however, is at the extreme opposite of that.
The country is one of the safest in the world and from personal experience, I can definitely vouch for that. You can safely explore it’s dimly lit side areas without fear.
When the sun goes down and the lights turn on, the Japanese streets, side streets and back alleys become an explorer’s playground. When I see Tokyo’s neon lights reflect in the puddles left over by the rain, the vending machines casting their blueish/pinkish hue on the street or lanterns faintly illuminating a nearby shrine, the photographer inside me just giggles like a little kid.
