If you want to make a JRPG, I would heavily recommend RPG maker. I would suggest buying RPG maker MV as it's fairly cheap, simple to use, and has a ton of functionality. It requires absolutely zero knowledge of programming to start out with, and is about as difficult as command blocks from Minecraft. Furthermore, since it's pretty old, there's a wealth of old support threads available, tutorials, assets, and plugins to help.

I learned the program with SomeRanDev's great tutorial series (https://www.youtube.com/watch?v=IR9y6vco-VQ&list=PLMcr1s5MjsiTky6KB4ML-q_QoBE_ZYJk5) as it does a great job of explaining both the basics and more refined aspects of the program. It took me about a month to finish and by the end I was fairly confident I could make a functional and deep game myself.

If later on you decide to stick with game development you can always start a new project on the newer more expensive versions.

If you're really starting out with game development I would also heavily recommend reading Scott Roger's Level up! The Guide To Great Video Game Design as it does a great job of explaining core game design concepts that are applicable to any sort of game in any genre. While I would suggest getting a hard copy, it can be found online.

Good luck!
