Well, I called them today. I made it clear that I have no experience with Japanese in a business setting, and that I'm still studying Japanese to complete a certificate course. They still want to set up an interview. I did say that I know basic Japanese, and I wasn't lying. If I get the interview I'll let them determine if my proficiency is a match for their job. I still need to brush up my skills though, just to make the best impression.

I won't be involved with the banking side btw, just IT. Thanks for the input folks!
