About 160 people, including Tokyo Governor Koike Yuriko and bereaved family members, offered incense and prayed for the repose of the victims. US B-29 bombers dropped incendiary bombs on parts of Tokyo, particularly on densely populated areas, burning down an estimated 270,000 residential buildings overnight. The United States dropped two atomic bombs on Japan towards the end of World War II – one called \”Little Boy\” on Hiroshima on 6th August 1945 and another called \”Fat Man\” on Nagasaki on three days later. Together, these two bombs killed some 220,000 Japanese citizens outright, with over 200,000 more dying subsequently from lethal radiation overdoses, according to a United Nations report. Japan has been leading the international discussion on disarmament and non-proliferation, promoting real change by calling on all nuclear weapon states to take measures toward nuclear disarmament while increasing transparency in military armaments, Japanese Foreign Ministry stated. \”Nuclear weapons and humanity cannot coexist,\” Japanese lawmaker Shinji Morimoto said earlier this month while addressing the meeting of the States Parties to the Treaty on the Prohibition of Nuclear Weapons.
