Apologies. It was the only "foreign" / "imported" thing I paid for while in Japan (I was road-tripping around the Fuji Five Lakes which does not have a train network at all.)
Accommodation and food prices seemed to be roughly around the same as before, but I did note some bottled soft drinks seemed to come in smaller sizes than before (450ml vs 500ml).
Checking my notes again just now, I did see the Nest Mini 2nd Gen for ¥2980, but that seems to be part of a Christmas promotion going on, so not a useful data point.
