Need help getting an appointment for license exchange in Osaka

Hi everyone, I’m a university student from the U.S. studying in Japan. I’ve been trying to exchange my driver’s license for a Japanese one, but I’ve run into a problem.

I called the Kadoma Driving Center during the Friday reservation period, but even after trying more than 500 times, I couldn’t get through. My semester starts on October 1, and once classes begin I won’t be able to skip. I can speak Japanese fine and I already have all the required documents.

I heard that Kadoma doesn’t allow people to line up and wait without an appointment, but I really don’t have another option right now. Has anyone been in this situation before? Is there any advice on how to actually secure an appointment, or any other approach I should try?

Any help would mean a lot—thanks in advance!
