東日本大震災（2011.3.11，簡稱311）發生至今即將屆滿4周年，但為數不少的受災居民仍過著離鄉背井的生活。本論文不避諱現況，更注意到東日本大震災之前完成、且充滿核能發電等議題表述的水上勉《故鄉》作品。近年來興起一股生態文學論述的風潮，逐漸注重人類與環繞人類、周邊的大自然間的對話研究。其中倍受重視的是對「場域的成覺」。本論文以此視點來探究夙稱人間生存根源故鄉。藉此剖析因核能發電所產生人類與生態．環境問之關係變化以及建構幾何學的「故鄉」形象。考察結果顯示：因核電課題的衍生，使得擁有故鄉情的人們面臨「擁護故鄉論」與「否定核電論」二選一的天人交戰局面。這也是在311之後的日本國民間無法取得共識的根本存在問題，心中糾葛更顯得難耐。而311之前的水上勉在《故鄉》一作中，早已透過幾何學的「故鄉」形象，明確地指出日本原發文學的癥結點

The residents in the stricken area where it spends a relocation left from the hometown is not few on now East Japan great earthquake (2011.3.11) 4 anniversary. In this thesis, Minakami Tsutomu's 'Hometown' in which the remark to the nuclear power plant published before 3.11 is seen is discussed based on this current state. This thesis searches for the phase of the hometown that is the root of the man existence from the aspect of ＂Sense of the place＂ by ＂Nature writing＂ (environmental literature) that values the conversation research with nature that surrounds man. As a result, this thesis has assumed the attempt of the construction of ＂Hometown＂ image as the relation and the topology of ecology and the environment caused by the nuclear power plant to be an investigative purpose. An unbearable, mental conflict of the person who holds ＂Love of one's home province＂ (4,P218) that they are made to stand in the dilemma of the alternative of ＂Hometown protection theory＂ and ＂Nuclear power plant denial theory＂ has come to the surface as a result of considering, because of the relation to the problem of the nuclear power plant. This is a deep existence problem of the mutually exclusive dichotomy that the Japanese is made to stand in post 3.11. Minakami Tsutomu has taken this problem in advance in 'Hometown' as topology, and has pointed out a deep problem of the modern civilization
