>>14376620This floating house after a tsunami shows you the absolute thickness of Japanese walls. They're tiny.
And whats worse, this is all because of the culture of disposable housing.
Hokkaido does indeed produce well insulated, sturdy, central heated housing that also features the same prebuilt showers, baths, kitches etc... the rest of Japan has but their cold climate forced people to be practical and actually build with both heating economics and cost in mind.
The average Japanese wastes so much fucking heat and cooling because their houses aren't insulated it's a fucking joke.
I don't turn on the AC in summer it's wasteful. Yeah nigger because you have 5 unclosing non insulated vents on your house, your windows are single pane with no air tight seal and your front door is made of metal with 0 insulation on it.
