The Okunoshima Poison Gas Museum is located on Okunoshima Island in Japan. This museum was established to educate visitors about the island's history during World War II when it was used for the production of chemical weapons, particularly poison gas. The museum features exhibits that detail the manufacturing processes and the impact of these weapons on both soldiers and civilians. In addition to the historical exhibits, the museum also highlights the island's transformation into a peaceful tourist destination. Visitors can learn about the environmental recovery efforts and the island's current status as a habitat for wild rabbits, which have become a popular attraction.
