Due to the pandemic of COVID-19, my research did not advance as much as I had expected. I initially planned to visit the Okinawa Prefectural Archives and the library at the University of Ryukyu in order to collect archival materials of Okinawan immigration to Peru. However, I could not conduct archival research. Despite this obstacle, I accomplished the following activities. 1)  I revised my literary criticism on a novel, Gaijin: La aventura de emigrar a la Argentina (2002) by an Argentine writer of Japanese ancestry, Maximiliano Matayoshi, and submitted it to a peer-review journal in the United States. I am waiting for an answer from the journal. 2) Through an online meeting initiated by Nobuaki Hamaguchi, specialist of economics in the context of Latin America, at Kobe University, and JICA’s researchers, Facundo Garacino and Yukako Nagamura, specialists on Nikkei community in Argentina and Nikkei community in Brazil respectively, we prepared a plenary session titled “Nikkei Communities Intersecting Latin America and Japan,” which was presented at the LASA/Asia 2022 conference. 3) Finally, I started analyzing a testimonial memory book through the ecocritical lens based on the notion of the Anthropocene, articulated by Timothy Clark.
