Next month will mark the 10th anniversary of the sarin gas attacks carried out by Aum Supreme Truth cult on a Tokyo subway during the morning rush hour. On Tuesday, NHK's documentary series "Project X" (NHK-G, 9:15 p.m.) will take a detailed look back at the medical-emergency measures implemented immediately after the attack.

More than 3,000 people were taken to various emergency rooms throughout the city, but the largest number went to St. Luke's International Hospital in Tsukiji. The head physician at the time, Shigeaki Hinohara, ordered all doctors to quit what they were doing and concentrate on treating the victims. Nobody knew what kind of poison had been released, and so the emergency treatment was for the most part improvised.

The documentary recreates the chaotic scenes of that fateful morning and recounts the dramas that unfolded and the heroic efforts of doctors.
