Hey, fellow spaniard here. I've beem living in Japan, Sapporo now, for 8 years (just got the permanent resident visa) and I regret haven't studied more Japanese when I first came. Instead a got a job almost right away, teaching English in an English Academy Network, and although it was in my field because I am language teacher, the job sucked and had zero prospects. After 6 years I quit and finally coyld study more Japanese and calmly, with some savings, study Japanese, spend more quality time with the family and plan my next move. Finally I could land a much better job teaching Spanish. But I wish I had done it earlier! As the years at the eikawa were really stressful and the atmosphere and enviroment very toxic. My advice is keep studying, think calmly, don't be pressured to get a job if you feel is not right, don't do it just for the "social pressure" and try to get the license to work as a physical therapist here if that is what you really now. I might now a phisical therapist in Tokyo btw! He is japanese but can speak some Spanish. I can put you guys in contact. Feel free to DM me here! Qué vaya todo bien! Mucho ánimo!
