Yamada’s project in Nakanojo stems from her days in Nakanojo; the experience of living inside nature and eating what grows beside herself. In her practice, Yamada aims to broaden the range of unity with the landscape she felt so that the responsibility to the environment can be felt alongside the blessing of the harvest. In green, while imagining the senses of plants, Yamada highlights the heirloom seeds in Kuni to unfold the bond between farmers, the seeds they grow, and their environments. While in THE ROOM, Yamada makes an imaginary room holding a self-sustaining ecosystem, referring to experiments of closed ecological systems and plant factories, which underscores the complexities of ecosystems and the difficulty of replicating them.
