Language Student interested in getting a commuter pass

I travel from kawagoe to akihabara 5 days a week, I want a commuter pass but I’m a little confused/have some questions so any answers/advice would be so helpful. I’m going to ask my school if I can also get a discount but I’m not sure if I can yet I think they do tho.

(1) I take tobu line and jr line, from what I know you can’t have a commuter pass combining those two so how would you go about that?

(2) I use a sucia card on my phone, do I need to get a physical card for the commuter pass?

Thank you in advance 🙏
