We Japanese... ＝我々日本（人） 日本語は、国もしくは国民の代表としての発言であれば、特に違和感を感じません。 From the eyes of a foreigner, even presidents/primes ministers/kings/queens seldom use "We (name of country)...". The phrase exaggerates the country, too much and sounds offensive. Imagine this: "We American will not surrender." In movies, it is a phrase before starting a war. 英語にすると強すぎると思いませんか。

nani?

I'm not sure about your question. Are you asking if "we Japanese" is correct? If so, then yes: "Japanese" specifies who "we" are.
