Japan has launched a survey in order to better grasp the financial situations of foreign technical trainees, as financial issues appear to be the reason many abruptly leave their host firms, a government official said.

The Immigration Services Agency and the Ministry of Health, Labor and Welfare began gathering information on 2,000 trainees across the country, including data on the pay they receive from their companies and the amount they owe in relocation expenses.

Thousands of technical trainees leave their host companies without notice every year seeking better wages, among other reasons, as many of them start their lives in Japan heavily in debt due to the huge expense of moving to the country.
