One of the key features of Japanese buildings is the use of seismic isolation bearings. These bearings allow the building to move horizontally during an earthquake, reducing the stress on the structure and minimizing damage.

Japanese houses are engineered using three primary philosophies: Taishin (Resistance), Seishin (Damping), and Menshin (Isolation). The most common method for detached wooden houses is a flexible "post-and-beam" structure reinforced with specialized metal joints and "earthquake-resistant walls" that use braces or plywood to prevent the frame from collapsing. Damping (Seishin) systems involve installing shock absorbers within the walls to soak up seismic energy, potentially reducing the force of the quake by up to 80%. For high-end homes and modern apartments, Base Isolation (Menshin) is the gold standard; the entire building is decoupled from the ground using layers of lead, steel, and rubber bearings. This allows the earth to move violently beneath the structure while the house itself remains relatively stable. Strict building codes updated after the 1995 and 2011 disasters ensure that even older wooden homes are often retrofitted with concrete foundation reinforcements to meet modern safety grades.
