The US is also pretty unsafe for women, minorities, and the disabled- again, it all depends on your location and the times at which you go out. Most big cities at night are pretty dangerous, even places you wouldn’t expect, like DC.
Japan does have some major issues involving their birth rates and overpopulation/crowding, on top of the issues that most countries have. I wouldn’t say it’s better or worse than the US, considering the recent measures our government has been taking to restrict marriage freedom and access to gender-affirming care.
