Look at how space is utilized in LAND SCARCE states.
Seems like a lot of work for the "shop assistant" as the high volume of pedestrian meant, quick emptying of the shelves. In fact, to save cost - Japan's convenience store sells breakfast, lunch and snacks. Only for dinner, do ordinary Japanese have opportunity to eat at home or in a family restaurant. Of course higher income Japanese has better location for meals.
In the effort to be efficient, the Japanese, Singapore, Hong Kong, Korean has taken a huge effort to popularized LUNCH BOXES.
Expensive Real Estate meant spending time in a family restaurant meant big budget meals, >US$10 a person!
To save on using restaurant space, the BEYOND PETROLEUM state has develop highly efficient packaged food, similar to European Union's sandwich, pastry lunch habit.
It cost less than US$3 to have a meal.
More people can be fed on high efficient means!
These means travelling by ROAD is very expensive, however the Japanese did not see it fit to charge punitive petroleum duties unlike Hong Kong and Singapore. The High Parking charges, High Road Use pricing is quite sufficient to keep the number of vehicles low - and perhaps caused the world's highest road courier charges!
I often wonder, why the Japanese did not use a ELECTRIC RAIL platform system instead of having so many TRUCKING systems. Just moving containers of various sizes, from the standard TEU to sub TEU. Afterall, the Japanese, and now perhap Korean, Hong Kong and Singapore has so large networked rail.
Homes in Japan, Korea, Hong Kong and "less true" in Singapore is small.
This saves ELECTRICITY cost in "heating" and "cooling".
The homes has common floor Kitchen, Hall, and dining and typically two small bedroom - sufficient only to position a queen size bed, make up table and a small clothing cabinet.
