你更願意生活在日本還是中國?
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，現在在中國差不多十年了。我在兩邊做生意，但住在離上幾小時車程的一個小城市。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.
兩國差不多。日本普遍很安全，中國有些地方犯罪率比其他地方高。但我在兩國都沒有受到過威脅。當然了，兩國比大部分西方國家要安全得多。禁槍，只有零星的暴力犯罪。在中國，有那麼點小可能，就是他們當與你的國家發生爭端時，中國政府策劃的針對外國人的暴力拘捕會殃及在你身上。明智的做法是隨時準備在事情惡化前出去避一避。尤其當你是個日本人的時候。而在日本，沒這種事。
Driving
駕駛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.
無論何時都是日本。我在兩邊開車都很多，在中國的里程超過300000公里。中國每天的車禍死亡人數是700人，涉及交通事故的人數幾百萬。簡直是大屠殺！電動車絕對是個威脅，它們完全無視交通規則。你開車必須要保持警覺，如果你防備着開，那就還好。信不信由你，我喜歡在中國開車，它是對你技術和智力的雙重考驗。Hygiene
衛生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。但不得不給中國過去十年的進步點贊。重要場所如機場都不差。街道也越來越乾淨了，但很大部分要歸功於清潔大軍的清掃。日本沒有人吐痰，城市裏當然也沒有，但是中國還有這個問題。看到過他們在餐館地板上吐痰。公共場所便溺在中國還是時有發生，但正在進步中。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.
需要我回答這個問題嗎？日本PM2.5指數在20-40徘徊。而我住的地方（中國）平均值是120，如果你相信官方數據的話。能見度總是很小。日本通常都是碧空如洗，也要看季節吧。日本現在的問題是核污染。但是除非直接生活在污染區，不然傷害也是有限的。中國未來的核能會在能源中佔比更大，所以核能這一項上，中國也並非是無風險的。當事故發生時，真實消息的迅速傳播是至關重要的。
