At this stage, it does not look like the Australian government will let us depart Australia for a very long time - until there is an effective vaccine!
So even though I have Easter 2021 off work, I very much doubt we will be making an appearance in Nagoya next Easter if Japan Do 8 takes place!
There are some hints that Japan will begin to open to tourists in March, but I think as we see virus numbers get worse over the winter that may be, regrettably, delayed.
