What are the Japanese eating over there? They’re always one-step forward than the rest of us. A demolition firm in Japan has adopted a game methodology of removing a doll made of stacked pieces, one by one starting from the bottom while not toppling it over to a real life task.

What they are doing is demolishing a 20-floor building by removing each level, floor by floor starting from the bottom to the top. They start by placing a set of strong computer-controlled jacks, replacing the column supporting the building. After they cleared everything on that floor, the jacks would slowly come down.

And then they start on the next floor. According to the firm, this is safer, faster by 20% (if bombed they would have to scrape through the debris), less noise and air pollution, and finally the materials can be recycled.

Watch the following time-lapse video and stand in awe of the Japs.

In case you’re curious, here’s the game that inspired them - it’s called Daruma-Otoshi.
