Most new high-rise dwellings in Japan use steel frames as the main structural component. This choice is mostly dictated by Japan's geography, which sits close to an earthquake-prone belt. Structures constructed using steel frames are lighter, stronger, neater, and easier to construct. However, they are more expensive than concrete or masonry. The steel structures are re-usable too, meaning you can move your units to a higher potential area should the need arise.
