Question Study Japanese autodidactically

This is a serious question, Is it possible to pass the N1 language exam without paying any teachers/classes/traveling to japan? (autodidact internet), 3hours per day.

My native language is spanish, i learned english,french and german (all at B2) only using internet, but japanese is going difficult...so im some afraid..

Thank you for reading me

Kami-Go,

You must practice speaking Japanese with Japanese people. If you cannot find Japanese people, then you must speak with non-Japanese people. Do you know how to find such people?

I would say it's certainly possible. Depends on your motivation and of course your learning style. As long as you set yourself a reasonable goal.
