Fifty-five years after Hiroshima and Nagasaki, their precise death tolls are also unknown. Estimates vary between a 1967 United Nations figure of seventy-eight thousand in Hiroshima and twenty-seven thousand in Nagasaki to more than thrice that in later Japanese accounting. Some experts take 140,000 and 70,000 as a best final estimate: a combined total some 25 percent higher than on Okinawa, where final guesses put the figure at about 150,000 civilians.
