大城立裕は，1967 年に『新沖縄文学』四号に発表した「カクテル・パーティー」で沖縄初の芥川賞受賞者となり，沖縄を活動の拠点とし，沖縄文学の発展を担ってきた。 今回，大城立裕の初期未発表作品が見つかった。「作品」として見つかった三作の詳細は以下の通りである。 「ゴルフ場の墓」・Ｂ５ 200 字詰め原稿用紙（ペラ）146 枚・1965年から1966年ごろ執筆と推測される。 「ながい夢」 ・Ｂ５ 200 字詰め原稿用紙（ペラ）242 枚・1967 年ごろ執筆。 「黙認耕作地」 ・Ｂ５ 200 字詰め原稿紙（ペラ）420 枚・1969 年ごろ執筆。 これらの作品は，それぞれ「ユタ」「沖縄演劇」「墓と信仰」という沖縄独特の文化，すなわち日本文学においてはマージナルなテーマを扱ったものである。沖縄の本土復帰前である1960年代に，既に大城立裕は，精力的に文学活動を行っていた。同時期に発表された作品を考察する上でこれら未発表作品は重要な意味を持つと考える。本稿では，未発表作品の紹介と分析を行い，既発表作品との関係においてこれらがどのような位置にあるのかを考察する。 OSHIRO Tatsuhiro is the foremost among the Okinawa writers in the post-World War II era. In 1967, he received the Akutagawa Literary Award for "Cocktail Party"- which was published in "Shin Okinawa Bungaku," No. 4-when Okinawa was still under U.S. military rule. Each of his novels has a distinctive feature that reflects the cultural climate of Okinawa; he had undertaken the task of developing Okinawa literature in Japan. I recently found the following three early, unpublished novels written by him: "Goruhujyo no Haka": 146 pages (Manuscript paper B5 forms of 200 letters)，it is assumed to have been written around 1965 or 1966. "Nagaiyume": 262 pages (Manuscript paper B5 forms of 200 letters), written around 1967. "Mokuninkousakuti": 420 pages (Manuscript paper B5 forms of 200 letters), written around 1969. The themes of these novels draw on Okinawaｎ culture, such as "Yuta," "Okinawa plays," and "Grave and religious beliefs"；these are marginal themes in Japanese literature. In the 1960s, OSHIRO was already an active writer. On considering his published works during this period, it appears meaningful to examine his unpublished works as well. This paper introduces summaries of these unpublished novels, analyzes them, and considers their position among his published works.
