To apply for license conversion, individuals will be required to submit a copy of their certificate of residence in Japan, regardless of their nationality. Japanese nationals who wish to convert driver's licenses obtained abroad may submit their certificates of family register instead. With the success of the government's policies to attract more foreign workers and tourists, the number of foreigners who converted their driver's license rose to 68,623 last year, more than double the figure from 10 years ago. Vietnamese were the largest group at 16,681, followed by Chinese and South Koreans, according to the agency. Under the current system, Japan allows drivers from South Korea and more than 20 other nations to convert their licenses without any written or driving test.
