The birth and progress of civilization are linked to the development of cities. This study investigates how people view and experience Tokyo, the populous megalopolis and major tourist hub. A digital art installation unveils a Tokyo that exists only through interaction. The authors reduce the city’s culturally dependent representation through a database using hashtags in 47 languages. The automated processing of the database finds trends in Tokyo’s representations on Instagram using Computer Vision (CV) and Natural Language Processing (NLP), yielding results in the art installation like current semiotic readings of the city.
