I may be mistaken, but I believe in Japan the standard is "build to remain habitable." as a result, skyscraper building techniques there are very different to the US.
“The Japanese Building Code (BSLJ) explicitly requires that buildings withstand moderate earthquakes with almost no damage, while collapse prevention and life-safety is required for severe earthquakes. It is expected that a typical building will be subjected to several moderate earthquakes during their service life, while the likelihood of occurrence of a severe earthquake during the same period is rare.”
