I totally agree I wouldn't really last living in Japan, and if I visited I would definitely be relying on their kindness and forgiveness. all that being said, I would not ask them to change a thing. From everything I've watched and read, their society is extremely clean and safe.

On a personal level, I think their weapons laws are extreme (historical fencing with steel trainers is more illegal there than owning a machine gun is in the US), their work culture is oppressive, their seniority system elevates people who don't deserve it while belittling people who do, and their complete allergy to rudeness is even more insulting than if they would just speak their mind. But this is all coming from a person who lives in an individualistic society were the murder rate is much higher, drug use is out of control, the streets are filled with litter, walking around at night is begging for a mugging, productivity and ingenuity are being outsourced to foreign countries, and degenerate lifestyles are considered a moral good amongst a significant portion of the population.

While I have a few theories, I don't know exactly what it is that they do that makes their society so much cleaner than ours, but whatever they're doing it's working.

Japan shouldn't change a thing.
