Reason for this article? 

Has anybody put forth a rational, NPOV argument for why this article's contents are incapable of being integrated into other articles about Japanese history and culture? We don't have articles for the Greek influence on Italian culture, the Chinese influence on Korean culture, the Indian influence on Chinese culture, the Arab influence on Persian culture, the Turkic influence on Anatolian culture, Japanese & American influence on modern Korean culture, etc. despite the fact that all of these influences were significant and frequently cited in academic literature - so why exactly is there a page for specifically ancient "Korean" influence on "Japanese" culture? I agree with the editors who state that the presence of such an article encourages tit-for-tat nationalism and it's as plain as day that such edit wars have already begun. Allowing this article to exist encourages future articles of the same sort and equally heated edit wars.

I suggest moving the article's contents into other articles relevant to the subjects cited. For example, the section about "Koreans" being on the committee that drafted the Taiho Code can be placed under Taiho Code, where it belongs in the first place.
