"Effective Monday, March 14, the visa fees applying to Tourist, Business and Student Visas will be as follows: Tourist Visa (VITUR): 11,200 yen"
"The Consular Section of the Embassy of Brazil informs that from March 12th, 2016, on the fees for TOURIST, BUSINESS and STUDENT will be charged according to the following table: Tourist Visa (VITUR) - INR 6.400,00"
