MANNAMI OSHIE (萬波教,1918.1.10 - 1997.12.1) graduated from Taihoku High School and Taihoku Imperial University, and later worked at Taihoku Second Normal School. During the Japanese Colonial period, he was active in Taiwan Literature Field as a lyric poet of “SHIKI(四季)”. In terms of artistic achievements, he was selected for the first Taiwan Governor-General’s Art Exhibition to paint covers and illustrations for many periodicals. After returning Japan, he continued to guide students in literature and arts, joined the public service system, and followed Aiba Yuryu(相葉有流) to write Haiku(俳句). A Japanese writer in Taiwan receiving little attention in the past, MANNAMI OSHIE was representative because of his creations and participation at that time. This article focuses on the discussion of MANNAMI OSHIE, delineating his life journey from birth to the receiving of “youliu reward(有流賞) ”for writing haiku in his later years. This article employs first-hand materials including newspapers, doujinshi(同人誌), student registration materials, and name lists, trying to articulate MANNAMI OSHIE’s life and works. Finally, this article also aims to place MANNAMI OSHIE under the context of“Japanese writers in Taiwan”and “Taiwan-Japan”HIKIAGE literature(引揚文學), in hope to make up for the less examined areas in the history of Taiwanese literature during the Japanese colonial period and give MANNAMI OSHIE a new historical evaluation.
