八尺門，雅稱海門，是和平島與臺灣本島之間的狹窄水道，故以八尺形容之；不僅位於基隆港出入的阨口，還具有巖奇、潮高、水清、魚豐的自然特徵。無論是臺灣文士或日本文士的古典詩作，皆可見到書寫八尺門這些自然特徵的普遍性意象，如：「逍遙的漁村」、「豐收的漁場」、「奇美的勝地」等。然而，在「八景」文化傳統以美化的理想風景來投射中國文士對逍遙自在理境追求的影響下，臺灣文士還以「海門澄清的理境」來描繪八尺門；又基於在地的關懷與對日本殖民現代性的認同，臺灣文士亦藉無線通信、五分車鐵道、跨海橋等溝通方式的書寫將八尺門形容為「隔海溝通的橋樑」。至於日本文士猪口安喜、久保得二，則憑其豐富的文史學養與帝國之眼而視八尺門為「思古的戰場」，抒發其憑弔該處豐富歷史之幽思與紀錄臺灣作為施政之用。本論文以日治時期八尺門相關古典詩約五十首，結合詩人寫作背景探究臺灣文士與日本文士詩筆下八尺門之普遍性意象與特殊意象的書寫情況與致異之因。

Bachimen is a narrow waterway between Hoping Island and the main island of Taiwan. It is named Bachi (eight feet) for its width and elegantly dubbed as Haimen (ocean gate) for being located at the mouth of Keelung Harbor. Bachimen is known for its unique natural features, including grotesque rock formations, high tides, clear water and abundant fish resources. These characteristics have inspired classical poetry by both Taiwanese and Japanese literati to portray Bachimen as “a slow-paced fishing village”, “an abundant fishing ground” and “a peculiar resort”. However, under the influence of the “eight views” cultural tradition, the Taiwanese literati described Bachimen as the “ideal state of Crystal Clear Haimen.” to reflect Chinese literati’s pursuit of a leisurely, carefree state. They also portrayed Bachimen as a “bridge of communication across the sea” by writing about various forms of transportation means such as wireless communications, the narrow-gauge train railway and the cross-sea bridge to show recognition and care for the local community. On the other hand, Japanese literati like Yasuki Inoguchi and Kubo Tokuji, with their rich literature and history education, viewed Bachimen as a “battlefield for reminiscing about the past”and expressed their deep thoughts about the rich history of the area. Based on a selection of about 50 poems related to Bachimen and the historical background of the poet’s creation, this paper explores the writings of common and distinct images of Bachimen in the poems of Taiwanese literati and Japanese literati as well as the reasons for such differences.
