Las demoliciones en Nihongo están basadas en un juego popular

Japanese construction firm Kajima Corporation is using an innovative new skyscraper demolition method to dismantle a pair of old company buildings in Tokyo. (Watch a time-lapse video.)

Unlike conventional demolition that begins at the top of the building, Kajima’s new method starts on the bottom floor, where the support columns are cut and replaced with giant computer-controlled jacks. Once the floor is demolished and the debris removed, the entire building is lowered and work begins on the next floor. The process is repeated for each floor until the entire building is gone.

Kajima informally calls this the daruma-otoshi method, after the old Japanese game consisting of a daruma doll made of stacked pieces that players knock out one by one without toppling the doll. (Watch a super slo-mo video.)
