I have one Japanese CC with my middle name on it. It's my JAL card, which is linked to my mileage account, which is (had to be?) registered with my full passport name, and the names had to 100% match between the credit card and the mileage account, at least according to the muppet processing the application.
It's fine for shopping and dining in person, but I have had absolutely no luck in using it to buy stuff online (including JAL tickets, which I end up putting on my ANA card that doesn't have a middle name). It may be that the names are registered in a wacky order in someone's computer system. The card itself is printed with my name as "FIRST MIDDLE LAST," but on some Japanese credit card terminals, my name inexplicably shows up as "MIDDLE/LAST FIRST."

However some places want your full name as it appears on your residency information, which can be funny at times because I said, "there's no box!" . Usually the solution is to input your middle name combined with your first name *with no space in between. Eg if your name is DOE, JOHN ADAMS it would appear as DOE, JOHNADAMS. I thought this was going to be an issue, but it never was. One of my cards issuer corrected my account by adding the space between while another just left it as is. If you leave your middle name off the application altogether, they might ask you to add it or to redo the application with your full name as it appears on your identification documents.
The application will also generally ask the applicant to input their Romaji name the way they wanted to be printed on the card itself (as the form was designed for Japanese people), that's where I just input my family and given name (without my middle name), again this hasn't been an issue either for me.
