Study/Living Abroad Help

Hey everyone! So I'm in an online homeschool/school (there are other students on Zoom but I'm at home) and I'm trying to put together my senior year schedule. There's an independent elective where you can propose your own initiative and I've always wanted to study abroad in Japan (I'm taking Japanese classes with my school right now). The problem is:

1) They've never had a student study abroad before so they don't know what to do.

2) Doing my online classes in the Japan timezone would have me waking up at midnight to attend them

3) If I were to do school in Japan, I would either have to pause my online school (which wouldn't give me credit) or somehow manage to do both my Japan schoolwork and my online schoolwork.

So my question is: Does anyone know a program that would allow me to live aboard for a semester but not attend a school? I would be fine with cultural events or having to do some local programs. I want to do it for the Winter/Spring Semester (about January to May) since most of the Fall semester programs are likely already filled/closed.

Thank you so much!
