Considering move to Osaka; need rental advice

Hey all 👋🏼

I'm a language education professional on sabbatical for the next couple years and coming to Japan for the next 6 or so months to scope things out and (FINALLY!) learn Japanese!

I've been doing a lot of research to figure out where I'm trying to settle in (options are Fukuoka, Osaka, Tokyo), and am trying to get the lay of the land a little bit.

This might seem trite to some of you, but I'm leaving the end decision to which place I can most easily find good quality housing in a centrally located neighborhood. I've been having a difficult time securing anything reasonable, as most places seem unwilling to rent to short-term tenants, especially on tourist visas.

Would love any scouting advice or opinions from someone located in Osaka 🙏🏼

Warm regards and appreciate everyone's help!
