I'm currently learning Italian. I guess it should be around level B2. At least I can function in the language and read books. Certainly not understanding every word but I can follow the story... anyway, in August I want to start learning Japanese while still continuing to master Italian. What would be the best way to do that?

I know learning them after another would be better but I love Japanese and always wanted to learn it. So I'm looking for a method to do both at the same time... How do I devide the immersion? Both languages on one day, or one day Italian and one only Japanese?

Has anyone any idea?
