Giant sinkhole in Japan repaired in matter of days

Some days ago, a giant sinkhole which had swallowed a chunk of road of a city block in the Japanese city of Fukuoka, has been filled in only a few days after it appeared, and this is a testament to the Japanese engineering and efficiency.

After the sinkhole appeard, a group of subcontractors had worked around the clock to fill in the the 30 meter (98 ft) wide, 15 meter (50 ft) deep hole by the 12th with a mixture of sand and cement. 

This job was so complicated but after that it only took another 48 hours to reinstall all the utilites, and resurface the road. There were no reports of injuries.

This gaping hole -- which started off as two smaller ones before merging into the larger cavity -- appeared only a 300 meters from  one of the city's main transport hubs.

My opinion

I'm completely surprised about this news, first of all to the giant sinkhole that had appeared it’s so big, amazing and then for  the speed in which it has been fixed.

I am completely sure that if this happened here, in Spain, it would take months to fix it. So I admire so much japanese work.
