Almost half of the 30 men working on one of the vessels were said to have come from Indonesia, Kiribati and Micronesia. It was explained that Kyowa Fishery Co. makes use of a government-approved scheme that allows foreign nationals to work on Japanese boats through agreements with overseas companies. The initiative was intended to relieve labour shortages in the fishing sector while also addressing the steadily ageing domestic workforce. Reports noted that on board the ships, support was provided in practical ways: signs were posted in eight languages, and pork-free meals were prepared to accommodate Muslim crew members from Indonesia. According to Yoshinao Naitō, who oversees Kyowa's purse seine operations abroad, the industry could no longer manage without these younger and physically capable foreign workers, given the rapid decline in Japan's own fishing labour force.
