The buildings were mostly wooden, and the bombs ​ — napalm and new incendiary devices containing magnesium and jellied gasoline — ​ set fire to the overcrowded downtown area, killing more than 77,000 people.
अनुमान लगाया गया है कि रात के 12 बजे से लेकर अगले दिन के सुबह 3 बजे तक, टोक्यो पर 7,00,000 बम गिराए गए ।
