A couple of weeks ago, a large sinkhole (30m x 30m, 15m deep) opened up in a major crossing in Fukuoka, the 8th largest city in Japan. Apparently this happened following work on an underground line nearby.
How long did it take to fix the sinkhole and re-open the road? One week.
Actually, it took only two days to fix the sinkhole, but authorities took another few days to conduct safety checks before authorizing the repair.
As the British newspaper The Guardian put it, this was “a typical demonstration of Japanese workmanship and efficiency”.
