A museum for inheriting the misery of war and the preciousness of life

Once upon a time, a large amount of poisonous gas weapons were manufactured on Okunoshima. At that time, in order to hide the actual situation of poison gas production, the Okunoshima area was treated as a blank area even in the map issued by the Army, so it came to be called an island that was erased from the map. Today, it has been developed as a vacation village and has become a health resort for the people. On the island, there are only a few remnants of that time, such as the remains of a battery, a power plant, and a poisonous gas storage. It was heartbreaking to have caused many casualties in the process of producing poisonous gas on the island, and the museum was built in 1988 with the aim of complaining of its misery and wishing for permanent peace. Many people now visit this place every year as a place for peace learning.
