Automatic opening doors but they don’t open by a proximity sensor, they open when you press the button. This is the optimal solution as the door doesn’t open needlessly but still allows for ease of access.
Ordering machines, where all your menu options are clearly listed and priced. Pressing on a combo of buttons will print a receipt which you can sit down and show the staff/cook your order.
Water (hot and cold) tapped straight to your dining table for self serve drinks.
Unfortunately becoming less applicable with the smartphone domination finally reaching Japan, but their flip phone technology.
Good livestock conditions so that food is actually edible raw
I would kill for their bidets everywhere.
If you like them, you can just buy one for your home. Expensive, but probably a better option than the murder you suggest.
Japan’s current fiber-optic commercial internet connections use optical fiber transmission windows known as L and C multi-core fiber (MCF) bands to transport data long distances at record speeds. Meanwhile we (USA) have fiber back to copper and Cat3 for the last few hundred feet in most cities at best making the entire idea into a bottle neck.
There are a lot of very good reasons to switch back to copper for the last portion of a run. I highly doubt that consumer internet in Japan is terminating fiber directly into peoples’ computers. Fiber is a lot more expensive both for the line, to run it, more prone to breakage, the network cards are more expensive, etc. It’s really not needed for most purposes.
Also no one uses cat3 for data and it can’t be run for ‘hundreds of feet’. And LC fiber IS used in the US - that’s a kind of connector not the kind of fiber.
I have fiber to home in Canada
Have fiber to home here in Arkansas in the US
