Wow, how did you learn Japanese Sign Language? I would love to learn some as well, and then maybe we could practice together! Good luck on your language learning!
Congratulations on returning to your Japanese studies! I would also like to teach English abroad, so I think it is so amazing that you’ve taught in so many great places! I hope that you have a really great time when you return to Japan. Good luck!
As far as places to visit, I have always wanted to go to Shirakawa-go in Gifu Prefecture. It’s a UNESCO World Heritage Site and has the beautiful Gassho houses!
