Part of my research in Japan has been to capture and map space, namely conceptualising air. Air as a material but also as a metaphor for something immaterial; energy or spirit. Japanese Shinto conceptualises many forms of the ‘unseen’ through Kami (神). I read Kami as an energetic and immaterial force and it seems broad enough to incorporate ancestor worship, nature spirits, animism and even aspects of Buddhism. Ritual processes often materialise concepts of the invisible by connecting them to our bodies and senses.
