The line was successful, and in 2006 was extended with 4 stations, to Toyosu.
Unusually, the elevated track does not end at the last station, it oddly continues for a few meters. This is not an urban art form (although I kind of like it...), the explanation is that when the station was built, a new extension was already planned, but construction hasn't started yet...
