Tokyo Electric Power Company Holdings Inc (TEPCO) has informed its subcontractors that foreigners coming to Japan for employment can engage in decommissioning work at the plant. Decommissioning work raises several concerns, particularly with radiation exposure. To prevent excess exposure, TEPCO has required foreign workers to have Japanese language abilities in order to accurately understand the risks communicated to them. Due to the new visa system, in which its goal was to bring in mainly blue-collar foreign workers, Japan is trying to increase its number of subcontractors. However, concerns about labor exploitations were raised; the Justice Ministry issued an ordinance requiring employers to pay wages equivalent to or higher than those of Japanese national. Notably, other major utility companies will not be following suit due to the risk of quality control, terrorism and information leaks.
