Public Transport in Osaka

Hello everyone!

I will live in Osaka for three months and I would like to plan my budget for the public transport.

I am a student under 26 (but not studying in Japan) and I was wondering, if there are any cheaper fares for that person group?

Do I have to apply earlier?

I am mostly working but I would also like to explore Osaka very slowly and make some daytrips to Kyoto, Ghibli Park, Nara, Kōbe and many other great places (still need to research).

I am grateful for any tips!
