日本文壇的兩大巨擘川端康成（1899-1972）與谷崎一郎（1886-1965），分別在他們的晚年寫出與先前作品風格迥異的話題作《睡美人》（1960年，刊於〈新潮〉）和《鍵》（1956年，刊於〈中央公論〉），引起各界相當大的矚目。 這兩篇堪稱近代老人文學的先趨‧由於其故事的主旋律均圍繞著生、死、與情慾等話題，加上發表的年代相近，的確值得深入探究。本論文主要分為兩部分，首先是以空間的觀點，來探討這兩部作品如何利用密室的構造來建構小說裡的情慾空間。接著將焦點放在男性所膜拜的女體上，試圖分析兩部小說中女體背後所蘊藏的含意。最後，經由兩部作品中，男女主角之間看與被看所衍生出來的權力與支配的關係，來進一步探討川端和谷崎不同的生死觀，並藉此一窺大師文學之堂奧。

Japan's literacy circle's two influentical writers, Yasunari, Kawabata (1899-1972) and Junichiro, Tanizaki (1886-1965), both came out with contrary works during their old age.
