USJ: Will anyone see my real name if we enter together?

I’m thinking of going to USJ and I’m going with a group of people. I’d prefer them not see my real name and I’m wondering if in the process of entering they’ll ever see it. I’m not sure if I need to sign up with my real name (if they ID check, I’m a resident in Japan) and if I do need to sign up with my real name is it likely they will see it during the check in process?

Edit: for all those asking i go by a preferred name and I just rather not people know my legal cause it sounds really stupid. I’m embarrassed by it and I’d just like to know if it’s something people need to see or not
