I don’t feel bad or angry at all. I just said, “I am Japanese”.
我并不觉得糟糕或者生气。我只是会解释说：“我是日本人。”

I know that they can’t recognise which one is Japanese or Chinese.
我知道他们没办法区分哪个是中国人哪个是日本人。

We are all similar faces. I think they feel Asian is all same. I can’t recognise which one is American or English either.
我们拥有相同的脸，我觉得他们认为亚洲人长得都一样，就像我也没办法区分美国人和英国人一样。

I would actually be impressed if a Westerner recognizes me as Japanese.
如果西方人能认出我是日本人我才会很惊讶。

I mean, even I sometimes can’t tell the Asians apart.
因为即使是我，有时候也没办法区分亚洲人。

It’s a reasonable assumption since what, almost 90% of the East Asian population is Chinese.
这是非常合理的一条假设，因为，中国人口占据了东亚人口的90%。

I usually politely correct them, teach them the Japanese greetings (Konnichiwa), and walk away to get on with my life.
我通常会礼貌地纠正他们并且教他们日本人的问候方式，然后走开继续过我的生活。

P.S. In reverse, I will also confess that despite living in Germany for the past two years, I have never been able to tell Italians and Germans apart.
备注：反过来，即使我在德国生活了两年，我也没办法区分意大利人和德国人。

My wife either ignores it, or politely corrects them, depending on context.
我的妻子要嘛忽视它要嘛礼貌地纠正他们，完全取决于当时的语境。
