Relatives of the people killed in a Tokyo subway train collision on March 8, 2000, observed the anniversary at the accident site Monday.
Next of kin and Yasutoshi Tuchisaka, head of the Teito Rapid Transit Authority, which operates the line and a network of subways in the capital, placed flowers in front of a monument to the victims.
The collision happened just after 9 a.m. about 100 meters northeast of Nakameguro Station on the Hibiya Line in Meguro Ward.
The collision occurred when the rear car of one train derailed and sideswiped a train going in the opposite direction on a parallel track on a curve, peeling open the side of a packed commuter coach. It killed five passengers and injured 63 others.
