Thank you very much! We've been lucky to visit twice and both trips were awesome (and very different as the second one was with our 8 month old baby). I've seen pictures of the snow festival, but we have enough snow in Quebec though for nearly 5 months, so we'll try to avoid that 😅
Our third trip should include Okinawa, which looks wonderful, and we are thinking about living there for 3 months and work remotely, because why not! ☺

Maybe you could try convincing your wife with the excellent food that you'll be eating there?!
