Mac Excel - VBA written in Japanese gets corrupted

I have an excel file with a password-protected VBA macro written with Japanese characters that I'm having quite the trouble of working with.

Whenever I tried opening it on Excel 2016 for Mac OS X, the file gives me several error pop ups and when I go to view the macro, the password protection is gone and when can view the VBA code, it is filled with mojibake text for all the Japanese characters.

I've run this same file with a Windows PC before and it works smoothly, so I'm thinking this is a Mac Office-specific issue.

Is there anyway to fix this on Mac Excel?
