Why the U.S. Didn't Drop Nuclear Bombs on Tokyo

The dropping of Nuclear Bombs on Hiroshima and Nagasaki effectively brought an end to World War II, but the question remains: why were these two cities chosen as the targets for the first and only use of nuclear weapons in war?

This article delves into the chilling and grim reasons behind these choices, their impact on the world, and the role of the atomic bomb in the broader context of World War II.

Beginning of the nuclear age

On August 6, 1945, six B-29 Stratofortress bombers took off from a base in the Pacific Ocean. Three planes scouted weather conditions at potential targets, while the remaining three carried observers, instruments, and the atomic bomb. The bomb was dropped on Hiroshima, instantly killing thousands and bringing the world into the nuclear age. Three days later, a second bombing run destroyed Nagasaki.

Many have wondered why these cities were chosen, as they were not as large as Tokyo or Osaka and did not have the most important war industry.

How the cities were chosen for annihilation

In May 1945, Germany had just surrendered, and the US was engaged in a costly war against Japan. A top-secret project had been underway to develop a nuclear weapon that could end the war. With the weapon nearly complete, the decision to use it hinged on finding the right target to demonstrate its power.

A committee was formed to determine the best targets for the atomic bomb, using criteria such as large urban area, strategic value, and location between Tokyo and Nagasaki. Seventeen potential targets were identified, but eventually narrowed down to four: Hiroshima, Kokura, Niigata, and Nagasaki.

Tokyo was initially considered, but ultimately removed from the list for a dark reason: the city had already been heavily damaged by firebombing, rendering it less suitable for showcasing the power of the atomic bomb.

Impact of the nuclear bombs dropped on Japan

The bombings of Hiroshima and Nagasaki had a profound effect on the world, shaping the course of history and the development of nuclear weapons. The decision to use these bombs demonstrated the destructive potential of nuclear weapons, leading to international efforts to prevent their future use in war.


The decision to drop atomic bombs on Hiroshima and Nagasaki was rooted in strategic and political considerations, as well as the desire to end a costly war.

The choices made during this time continue to shape our understanding of warfare, the development of nuclear weapons, and the importance of pursuing peace.


Frequently Asked Questions about the nuclear bombs dropped on Hiroshima and Nagasaki

Why were Hiroshima and Nagasaki chosen as the targets for the nuclear bombs?

Hiroshima and Nagasaki were chosen as the targets due to their military and strategic importance. Hiroshima was a significant military hub, with several Japanese army headquarters and key communication centers. Nagasaki was an important port city with major shipbuilding facilities and naval installations. Both cities were relatively untouched by prior bombings, making them ideal for observing the effects of the atomic bomb.

Why was Tokyo not targeted?

Tokyo was not targeted for several reasons. First, the city had already been heavily damaged by conventional bombings. Second, there were concerns about the potential for increased civilian casualties if an atomic bomb was dropped on Tokyo. Third, dropping the atomic bomb on Tokyo would have made it more difficult to assess the bomb's impact due to the city's extensive destruction. Lastly, the US was seeking to maximize the psychological impact of the bombings, and hitting two less-damaged cities would demonstrate the destructive power of the atomic bomb.

What were the primary motivations behind using nuclear bombs in Japan?

The primary motivations for using atomic bombs were to force a swift end to the war and to minimize American casualties. The US military believed that a prolonged invasion of Japan would result in significant casualties, and that the use of atomic bombs would shock the Japanese into surrendering.

How did the Japanese government react to the bombings?

The initial reaction to the bombings was shock and disbelief, as the destruction was unprecedented. While some officials argued for continued resistance, others advocated for surrender.

Did the bombings of Hiroshima and Nagasaki lead to the end of World War II?

While the bombings were not the sole factor leading to the end of World War II, they played a significant role in Japan's decision to surrender. The bombings, coupled with the Soviet Union's declaration of war and invasion of Manchuria, convinced Emperor Hirohito that continued resistance was futile. On August 15, 1945, Japan announced its surrender, effectively ending World War II.

  1. I read a great many years ago that Nagasaki and Tokyo were the two primary cities to be bombed by the Flying Fortresses, but Tokyo was covered that day by a dense layer of clouds and the bombardiers couldn't clearly make the city out and the people in the B29 went to their alternate target; Hiroshima. I don't know that it's true but I read that as fact many decades ago. Dave
