Purely incidental, but: I check housing prices in Tokyo every once in a while and I've found a lot more of what I'd consider "a good deal" in the last couple of months. Not buying a place anytime soon, just find it interesting to see.

I also took a short trip to Okinawa (the beach islands of Japan) and the Airbnb prices were anomalously low, in fact it was more expensive renting a car for the time I was there than my stay. Not surprising, considering that last year ~31 million tourists visited Japan but this year that number must be very low.
