A photography exhibition about Japanese biological and chemical warfare in China during World War II opened in Tokyo on Saturday, marking the 70th anniversary of the end of the Chinese People's War of Resistance against Japanese Aggression. The exhibition displayed a total of 405 photographs showing how Japanese Unit 731 used Chinese for vivisection in order to develop biological weapons, and the pain Japanese war atrocities inflicted on the Chinese victims over the past 70 years. The exhibition was sponsored by the China Foundation for Human Rights Development and Japanese non-governmental organizations, including the Japan-China friendship Association. At the opening ceremony, representatives said that the exhibition was aimed at educating Japanese, especially the younger generation, about this part of WWII history in order to help build a more peaceful and friendly relationship between China and Japan. "Many Japanese don't know about the biological warfare and the Chinese victims who suffered from Japanese war crimes, even 70 years on. This exhibition is aimed at teaching more Japanese about those victims' lives," said a Japanese representative. The exhibition attracted visitors from all walks of life and will run until August 18. "This show has revealed so much damage that I wasn't aware of. I never knew that Chinese people suffered so miserably during that war," said a young Japanese visitor. On the same day, protesters took to the streets in front of the controversial Yasukuni Shrine, with those opposing the shrine and Japanese Prime Minister Shinzo Abe's security policies clashing with nationalists, who gathered to honor the soldiers who died in the war. Hundreds of riot police were deployed to separate the angry groups.
