Bank account for € in Japan?

Hello!

I heard there are bank accounts where you can deposit other currencies apart from Yen and which usually give interests. Can anyone recommend which one I could look up for €? Ideally:

• I can move money from MUFJ to this account for free (domestic wire) every month
• exchange is good
• they give me interests
• no fees to keep it open
• once per year I then move money from this account to MUFJ or abroad

Thanks!
