A ruptured water main caused the massive sinkhole to open up on a 5-lane road near the main Hakata railway station last Tuesday, Nov. 8, according to ABC News partner NHK, Japan Broadcasting Corporation.
The giant crevice caused power outages, prompted the evacuation of nearby buildings and disrupted traffic in the city, which is home to about 1.5 million people in southwestern Japan.
Engineers and construction crews worked around the clock and were able to restore most utilities -- including gas and water -- and fill in the hole by Saturday, Nov. 12, according to NHK.
A new road was paved, repainted by Monday, Nov. 14, and was re-opened the following day after inspections.
NHK captured a mesmerizing time-lapse video of the speedy six-day repair condensed into less than three minutes:
