The second video is even better, as it deals with Japanese home appliances including clothes washers. There is even a refrigerator with a vacuum drawer to help preserve foods. LOL, the marriage of a fridge and a vacuum cleaner, who would have thought it?
My own experience in Japan was that their laundry was very rough. I stayed in a hotel there for about two months, and the staff would take my socks and such and wash them. They'd come back clean but VERY stiff, and not from starch either. I'm told they used cold water only, which explains a lot. There was actually a little laundry room at the company factory we could use... it was unusual for Americans of the day (mid 1990's) because it was a top loader with a wash plate. The American engineers were fascinated by it. I just let the hotel wash my stuff ;-).
PS-The factory was owned by Matsushita, so any appliances there were either "National" or "Panasonic"...
Oh, and the one item I found in a hotel room that to this day I wish I could get here: It was a small hot plate, not much bigger than a cup warmer. But it was a little induction plate, with a magnetic stainless jug that held maybe a pint. You just filled the jug with water, put it on the plate, switched it on, and it would very rapidly come to a boil for tea. It would shut itself off as soon as it boiled. Very handy. I've yet to be able to find anything similar here, even searching on-line. Silly me, I bought a CD/Cassette/Radio boom box when I was there, but never thought to look for one of those induction cup boilers. I just assumed I'd be able to find one stateside.
