The former site of the headquarters of Unit 731, a notorious Japanese germ-warfare unit during World War II (WWII), reopened to the public on Friday, featuring a special exhibition showcasing evidence of its germ-warfare activities.
Nearly 2,100 items, including archives, historical materials, relics and publications collected by the Exhibition Hall of Evidences of Crime Committed by Unit 731 of the Japanese Imperial Army in recent years, were unveiled at the exhibition, according to Zhang Yang, deputy director of the facility.
Unit 731 was a top-secret biological and chemical warfare research base established in Harbin as the nerve center for Japanese biological warfare in China and Southeast Asia during WWII.
At least 3,000 people were used for human experiments by Unit 731, and more than 300,000 people in China were killed by Japan's biological weapons.
Since last winter, the exhibition hall has attracted over 3.5 million visitors.
