Oh, I'm sure it's going to be fantastic. I have friends who visited Japan before and they loved it :) It's not that far away for you so I'm sure that you can make it there again :)
Thank you for the tips! At least now I know that there is really so much to see that one month is a must :)
I will definitely wait until after 2020 then as I want to enjoy it in its full glory :)
Hope you had a lovely weekend!
