Across Japan, foreign workers are keeping factories, fisheries and workshops afloat. But as wages rise in neighbouring countries, many business owners worry that Japan may no longer be an attractive destination for this workforce.
In Choshi, home to a large fishing port in Chiba prefecture, east of Tokyo, one long-established cannery offers a glimpse into both Japan’s dependence on foreign workers and efforts being made to retain them.
Ho Thi Thuy Nhung, 38, begins work at 8am on the assembly line. Her job rotates every few hours: operating a machine that cuts off fish heads and tails, removing foreign objects by hand, and carefully lifting fish from a grilling machine. Each task requires focus and precision.
“When I first started, I was confused because there were so many steps,” she said. “But I learned quickly. The work changes often, and once I got used to it, I actually found it enjoyable.”

She came to Japan last summer, leaving behind her husband and their eight-year-old son. Of the 80 people employed at the cannery, 16 are technical intern trainees from Vietnam.
