Hiroshima, Japan is now habitable.

Japan is just a small island country with a lot of mountainous terrain, and with the many volcanic areas and frequent eruptions, thus most of the places close to the volcanoes are uninhabitable, excluding the fact that there aren't a lot of places to live. So in order to alleviate the country's housing woes, many people still live in Hiroshima and Nagasaki.

On August 6, 1945, a U.S. Army Air Corps B-29 Superfortress bomber "Enola Gay" dropped the nuclear weapon "Little Boy" on Hiroshima. The bomber was specially modified to carry atomic bombs. An estimated 71,379 civilians were killed and Hiroshima was devastated. This was the second explosion of the atomic bomb and the first time it was used in military operations. The atomic bombings of Hiroshima and Nagasaki forced Japan to surrender on August 15, 1945, the sixth day after the second attack.

After the atomic bombings, the city of Hiroshima was rebuilt as a "Peace Memorial City". The ruins of the Hiroshima Industrial Incentive Center, the building closest to the site of the detonation, were named the "Atomic Bomb Dome" and made part of the Hiroshima Peace Memorial Park. The city hall has been advocating for the abolition of nuclear weapons and world peace, and since 1968 has protested against the detonation of nuclear weapons everywhere.

Hiroshima was rebuilt after the war with new modern buildings. Several civic leaders and scholars discussed reconstruction plans, and in 1949, on the initiative of Mayor Shinzo Hamai (1905-1968), Hiroshima was declared a "city of peace" by the Japanese parliament. As a result, Hiroshima City has been attracting more and more international attention, and international conferences on peace and social issues have been held here.
