After releasing raw sewage into a stream for four decades, East Japan Railway Co. has finally put a plug in its faulty station toilet in Tokyo this week by fixing its plumbing.

The remodeled toilet near the south exit of JR Oji Station in Kita Ward reopened Thursday after it was shut down early last month following the discovery of unsuitable piping.

During the railway's recent check on station facilities, a sewage pipe from the toilet was found to have been erroneously connected to rain-water drainage, JR East said.
