Good luck with the move. I can't imagine it's going to be easy with all the restrictions right now. Mind if I ask how/why you're relocating to Japan? Just curious, as I lost a couple of clients this year who applied for spouse visas through their Japanese wives and are hiding out in the Kanto countryside till this is over.
I suppose it interests me as I actually relocated to Japan at the height of the last, last, last plague the Chinese gifted the world with (SARS in 2003). Getting off the plane at KIX and seeing everyone (but me) masked up scared the living shit out of me, and I wasn't even an OCD germophobe just yet.
I am jealous, however, stuck here stateside waiting this out. I'd probably murder someone right now for a soak in a nice rotenburo after a few rounds of real Japanese Asahi, some imo on the rocks and of course the kind of special massage found near Kanda Station.
In any event, if you need any pointers (and not just on where to get your dick played with) the abominable human beings here are a genuine treasure trove of information.
