A road has caved in near a major railway station in southern Japan, forcing authorities to block off nearby areas.
The massive sinkhole near Hakata Station, the biggest station on the southern island of Kyushu, caused power outages and disrupted traffic near the site, on Tuesday morning broadcaster NHK reported.
There were no reports of any injuries.
The sinkhole opened up at 5.15am local time and kept growing, the report said.
Local authorities suspected the cause of the accident was linked to ongoing construction work for an underground rail system.
