Compared with the past, our living environment and state of existence have drastically changed. Anxieties prompted by the ecology's deterioration and resource depletion are constantly attacking people's mindsets. Perspectives and thought processes related to the situations are rapidly overlapping, making it difficult for people to take a brief moment to preserve or relish anything in a sincere manner. I hope that through the "Memorandum" series to compose a visual and psychological file based on individual experiences for the living environment and state of existence that we dwell in. The Memorandum's Ode to Joy is one of the series. Its composition is in the shape of a “solitary island”, and expresses a sense of black joy sparked by the compressed living environment on Earth.
