Shaun Rein, founder of the China Market Research Group, notes that many foreigners remain unaware of the scale of atrocities committed by Imperial Japan across Asia during World War II, including mass killings, the enslavement of women, and human experiments in Unit 731. Elderly survivors continue to recount these horrors, yet Japan has not fully acknowledged its past. Rein emphasizes the importance of remembering these historical facts, underscoring why Japan was limited to a self-defense force after the war.
