[IWantOut] 24F Japan -> Czechia

Hello all. Due to my religious beliefs (I'll not tell you more about that here, sorry), I would like to move to Europe. I chose Czechia because I love its language and religion (ex. Jan Hus). I am considering to move there within a year and I'd love to know about:

1. I would NEVER study in English. I really want to study in Czech. That's because I think it shows respect to the terrain where they accept me. Am I rare? Currently I have A2 or B1, and I would like to improve my Czech (I am studying it for hours daily)
2. I am also considering to move there using working holiday visa, but should I go back to my home country to continue my study?
3. what can I do to NOT to go back home? I don't want to die in Japan (due to my religion) Thank you in advance.
