Between 1948 and 1951 the ashes of 105,400 people killed in the attacks on Tokyo were interred in Yokoamicho Park in Sumida Ward.
After the war, Japanese author Katsumoto Saotome, a survivor of the 10 March 1945 firebombing, helped start a library about the raid in Koto Ward called the Center of the Tokyo Raids and War Damage.
