At this workshop, we will work with Asa Ito to put together a user manual for vacant premises. Following lecturers by various speakers on the theme of the vacant premises serving as the venue, participants will consider how to deal with vacant premises. The three lecturers will be Jun Nakano, who will speak on the topic “Yokai Phantoms and History,” Hashimoto Satoshi, who will speak on the topic “Art and Directional Auspice,” and Takuji Yamada, who will speak on the topic “Bacteriology.” Why not join us to explore the potential of vacant premises, including not only things that are visible or exist, but also the unseen and non-existent.
