I grew up bilingual and attended a Japanese school on saturdays during elementary school. I talk a mix of Japanese and my other native language (German) to my mother and understand Japanese TV and can have normal conversations with my Japanese relatives.
Still, I feel like my Japanese is out of practice as I have rarely used it after I moved out from home and I struggle especially with formal language and advanced vocabulary.
I want to go to Japan next year to work at a hospital for 2 months and would really like to brush up especially 敬語 (formal language) and some harder vocabulary but have no idea where to start or what books would be good for that.
Does anyone have recommendations?
Should I even use books or just immerse myself in the language again?
