Some experts are concerned that the language barrier may even discourage some foreigners from paying their taxes. On the morning of Feb. 16, the first day of the income tax filing period, taxpayers flocked to the tax filing area set up at the National Tax Agency's Tokyo Regional Taxation Bureau in the capital's Chuo Ward. There were taxpayers who appeared to be foreign nationals, glancing around anxiously and consulting with the staff. All the information boards were written only in Japanese. Arbenita Sopaj, 30, was one of the foreigners looking to file her taxes. Sopaj came to Japan from Kosovo in Eastern Europe about five years ago and is working as a university assistant. She said the filing was "little bit difficult," but the Japanese staff there who helped her "was very polite and made sure that I don't have any difficulties."
