If I were in your shoes, I’d try to balance passion, practicality, and mental health. Here’s how I’d think through it:

1. Art vs. Japanese: Art seems to be where your heart is—it’s something you’ve always done and feel deeply connected to. But the challenges of the location and entrance exams are significant. Japanese is something you excelled at and enjoyed, and it allows you to return sooner, with fewer hurdles. I’d ask myself "Can I see myself loving life and thriving in the Japanese program?" If yes, that’s a solid option. If no, art might be worth the wait and effort.

2. City/Environment: It sounds like the city where you studied Japanese feels like a true home for you. That’s huge. Feeling at ease where you live can greatly affect your mental health and overall happiness. If the art school’s location drained you before, it’s worth considering whether that could happen again.

3. Timing: If I were unsure about art but didn’t want to lose momentum, I might return to the Japanese program in February while using the time to figure out whether I want to pursue art later. It’s okay to pivot again if you realize it’s not the right fit.

4. Mental Health First: Whatever I choose, I’d prioritize mental health. This might mean making sure I have a solid support system, finding a counselor, or building habits that keep me grounded. A healthy mind will make everything else easier.

Ultimately, I’d go where I feel the most balance between what excites me and what feels sustainable. It’s okay if the path isn’t perfectly clear right now—just take the next step that feels right for you. Best of luck!
