I'm going to Japan next week to work at the Expo for 8 weeks. I will be working two 12-hour days, followed by 2 free days, which I'd like to spend travelling, and so on. During my working days, I'll be working as a hostess/pavilion assistant in my country's pavilion, speaking almost exclusively Japanese all day every day to the visitors.
During the free days, I want to visit a bunch of lesser known places that are suitable for 1 or 2-day trips from Osaka, as I've been to Japan before and have seen the main tourist cities/places already.
What would you do with these free days to immerse more in Japanese? I will be there alone. My current level is N1 and I'd like to take the test again in December to improve my score after these hopefully successful two months of immersion (just for fun, I don't really care for the test nor need it for anything).
TIA
