Japanese Yen to Brazilian Real

No. The IOF (Imposto sobre Operações Financeiras) is a federal tax that applies to Brazilian residents and cards issued by Brazilian financial institutions. If you are using a credit or debit card issued in your home country, the Brazilian government does not charge you IOF. Keep in mind, however, that your home bank may charge its own foreign transaction fees.

Yes. If you bring foreign currency (such as USD, EUR, or GBP) and exchange it for Reais at a local exchange bureau (casa de câmbio) or a bank inside Brazil, an IOF tax is applied. The exact rate depends on the direction of the exchange:

0.38% is applied to sales operations by the client (e.g., when you sell your foreign currency to buy Brazilian Reais).

3.5% is applied to purchase operations (e.g., if you convert your leftover Brazilian Reais back into foreign currency before leaving the country).

This tax is mandatory, collected by the institution processing the exchange, and will be factored into your final payout.

No, you cannot. Unlike the Value Added Tax (VAT) systems in many countries that allow tourists to claim tax refunds on physical goods, the IOF is a tax levied directly on the financial transaction itself. It is strictly non-refundable.
