Can i order a pass while in Japan?

I am travelling to Japan on the 18/9 where i am staying in Fukui for a month, before going to tokyo for 2 months. I would therefore like to see kyoto and osaka and maybe kobe in that first month but i don’t know when i would like to do it, so I was wondering if i could order a regional pass while already being in Japan if i am only there on a tourist Visa? And what kind of pass would you recommend for me?
