難しい英文の和訳をお願いします。
Discourses of the Vanishing: Modernity, Phantasm, Japanという本の一部なのですがわからないので解釈がしやすい和訳をお願い致します。 Disclosed in the image of assimilation with its insistence on the final imperviousness of Japanese culture is a profound categorical uneasiness,an uneasiness contained only by keeping the spheres of the economic and cultural
distinct. Americans know that the Japanese are technologically and economically modern―with factory robot,electronic toys,and megabanks ーbut culturally,Japan is “an exclusive,homogeneous Asian ocean-and-island realm,
tribal,intricately compact,suppressive,fiercely focused.” Tribal? This description,from Time magazine,reveals the popular extent to which Americans perceive Japanese as culturally not modern, a nonmodernity sustained by patterns of social organization and symbolic production that persist no matter what goes on in the fabulous realms of advanced capitalism.
ちなみにTribal? This description,from Time magazine,reveals the popular extent to which Americans perceive Japanese～ のwhichの先行詞はextentでいいのでしょうか？
またこの場合はどの様な用法で使われているのでしょうか？ そちらの方もよろしければ教えてくださいますか？よろしくお願いします。
