Through the analysis of English in the linguistic landscape (LL) of Tokyo, this article demonstrates the diverse functions of English on signage and argues that the use of English in different areas of Tokyo mirrors the distinct socioeconomic characteristics of each area, aiming to highlight how English contributes to shaping the multifaceted Tokyo's cityscape. This study specifically contrasts the three areas: Asakusa and Tsukiji, Shibuya, and Roppongi and Azabu. The data consists of photographed signs, supplemented with fieldnotes, obtained from fieldwork in 2023. Considering all the aspects of the observed signs, the diverse English use on signage can be viewed as a manifestation of its proliferation and localisation as a global language, adapting to a diverse audience, including Japanese locals, visitors from overseas, and local foreign residents. As a result of such manifestation, along with the varied functions and interplay with social contexts, the aggregate of English signs of each area collectively crafts the complexity of Tokyo's mosaic cityscape.
