This chapter explores the affective significance of the catastrophic 9.1-magnitude Tohoku earthquake that occurred on March 11, 2011, with a focus on the ongoing impacts of the resulting tsunami debris, which continues to appear on beaches in Haida Gwaii over 20 years later. The case is made that matter, or debris, has affective power and becomes entangled both in the ocean and in collective psychic and cultural experiences in powerful ways. Particular attention is paid to a Harley-Davidson motorcycle that was part of the Japanese debris, including consideration of historical conflict between Japanese and American motorcycle histories.
