你更愿意生活在日本还是中国?
I have lived four years in Japan and now almost ten in China. I do business in both, but am based in a regional city a couple of hours from Shanghai.
我曾在日本生活四年，现在在中国差不多十年了。我在两边做生意，但住在离上几小时车程的一个小城市。Personal Safety
人身安全About the same. Japan is universally safe, but some areas of China have a higher crime rate than others. However I have never felt threatened in either. Certainly both are much safer than most Western countries. No guns to speak of and very little violent China, but not Japan, there is always the slight chance of government-orchestrated violence against or arrest of foreigners if there is a dispute with your country. It is wise to be aware and to be ready to get out for a while if things start to turn nasty. This is especially true if you happen to be Japanese.
两国差不多。日本普遍很安全，中国有些地方犯罪率比其他地方高。但我在两国都没有受到过威胁。当然了，两国比大部分西方国家要安全得多。禁枪，只有零星的暴力犯罪。在中国，有那么点小可能，就是他们当与你的国家发生争端时，中国政府策划的针对外国人的暴力拘捕会殃及在你身上。明智的做法是随时准备在事情恶化前出去避一避。尤其当你是个日本人的时候。而在日本，没这种事。
Japan every time. I have driven a lot in both, with over 300,000km in China. 700 people a day perish on Chinese roads and millions are involved in less serious accidents. It is carnage! e-bikes, which appear to operate in a separate rule-free dimension oblivious to other traffic, are a menace. Having said that I do not feel in as much danger as you may think. You must drive defensively and be very alert. If you do that you will be fine. Believe it or not I enjoy driving in China. It is a test of both skill and mental discipline.
无论何时都是日本。我在两边开车都很多，在中国的里程超过300000公里。中国每天的车祸死亡人数是700人，涉及交通事故的人数几百万。简直是大屠杀！电动车绝对是个威胁，它们完全无视交通规则。你开车必须要保持警觉，如果你防备着开，那就还好。信不信由你，我喜欢在中国开车，它是对你技术和智力的双重考验。Hygiene
卫生Japan, but have to give China points for improvement in the last ten years. Major facilities like airports are not too bad. Streets are getting better too, but largely due to an army of cleaners that picks up after a thoughtless, littering spitting in Japan, certainly not in cities, but still an issue in China. Have seen them spit on the floor in ic urinating still happens in China, but improving.
日本。但不得不给中国过去十年的进步点赞。重要场所如机场都不差。街道也越来越干净了，但很大部分要归功于清洁大军的清扫。日本没有人吐痰，城市里当然也没有，但是中国还有这个问题。看到过他们在餐馆地板上吐痰。公共场所便溺在中国还是时有发生，但正在进步中。Pollution
污染Do I need to answer this? In Japan pm2.5 readings hover around 20–40. In my area it averages about 120, if you believe the official numbers. Visibility is always poor. Japan generally has clear blue skies, depending on the ear pollution in Japan is a current problem (edit suggested by another Quoran - thank you) but unless one lives in the immediate area the effects are limited. In China nuclear plants are going to be a bigger part of the energy mix in the future, so it is not free of risk. When and if accidents happen the rapid and truthful dissemination of information is going to be vital.
需要我回答这个问题吗？日本PM2.5指数在20-40徘徊。而我住的地方（中国）平均值是120，如果你相信官方数据的话。能见度总是很小。日本通常都是碧空如洗，也要看季节吧。日本现在的问题是核污染。但是除非直接生活在污染区，不然伤害也是有限的。中国未来的核能会在能源中占比更大，所以核能这一项上，中国也并非是无风险的。当事故发生时，真实消息的迅速传播是至关重要的。
