I’m so overwhelmed and confused by the ISPs here.

I’m moving into my first apartment in Tokyo in a few days and I’m trying to sign up for decent fiber internet. Yes I’ve read the wiki. I’ve also spent several hours reading reddit threads and still don’t wtf I’m supposed to apply for. It seems like you need to be an expert in networking to even understand all of this. In my home country you just choose the cheapest ISP and apply – they are all basically the same 😅.

I think my building has fiber but the apartment doesn’t? When I asked my landlord he said “just use NTT” but I’m still not really sure what that means. Isn’t all internet here NTT?

Is someone able to ELI5 what I should apply for? I work from home so need something decent.

I also don’t have a credit card yet so that eliminates any where that’s the only payment option 🙁

Thanks in advance.
