Best way to use some euros in a MUFG foreign currency account?

Hi all,

I have a few thousand euros I received from an inheritance in a foreign currency account in MUFG bank and I would like to use them to pay the plane ticket for me, my wife and my son to visit my parents at my home country.

Checking the banking app the only option I have is to exchange it to yen in my savings account and then use it as yen to pay my credit card, however, I was wondering if someone did anything different or if there is a better way than to rely on the bank exchange rate for foreign currencies?

For example, do you know if there is a way to use the foreign currency directly to pay the credit card balance or the plane tickets avoiding the currency exchange to yen?

Thank you for your comments!
