Allied naval bombardments of Japan during World War II

Understanding the Allied Naval Bombardments of Japan

The Allied naval bombardments of Japan in July and August 1945 were a critical phase in the final months of World War II. These attacks, carried out by US Navy, Royal Navy, and Royal New Zealand Navy warships, targeted industrial and military facilities with devastating effects. Imagine these battleships as giant sentinels, their guns like thunderbolts striking at the heart of Japan’s war machine. The primary goal was to provoke a response from the Japanese military and expose their aircraft reserves to destruction by Allied fighter planes. But what if we asked: Could these naval bombardments have been avoided? Or were they inevitable given the circumstances?

Strategic Targets and Methods

The attacks were conducted with precision, using battleships and cruisers that fired over 2,000 shells in a single bombardment. The Kamaishi’s ironworks, for instance, was hit by 2,351 shells, sinking warships and merchant ships while damaging eight more. This level of destruction is almost unimaginable, yet it pales in comparison to the broader impact on Japan’s industrial capacity.

Impact on Industrial Production

The Allied bombardments disrupted industrial production significantly. For example, the attack on Kamaishi’s ironworks resulted in a loss equivalent to four weeks of pig iron production and 2+1⁄2 months of coke production. This is like halting an entire factory line for several months, causing immense economic damage. The Japan Steel Company‘s facilities and the Wanishi Iron Works in Muroran were also targeted, further exacerbating Japan’s industrial crisis.

The Hitachi Bombardment: A Mixed Bag of Results

On July 17-18, a group of Allied warships, including the battleships Iowa, Missouri, Wisconsin, North Carolina, Alabama, and HMS King George V, conducted a bombardment on the city of Hitachi. The attack was aimed at industrial facilities but resulted in only three targets being hit. While there was slight damage to industrial areas, urban areas and essential services suffered considerable damage. This scenario raises questions about the effectiveness of naval bombardments compared to air strikes.

Further Air Strikes and Submarine Attacks

The Allied fleet continued its operations with further air strikes in Tokyo on July 18, including an attempt to sink the Japanese battleship Nagato. Meanwhile, US Navy submarines like USS Barb and USS Trutta launched attacks using rockets and shells, causing significant civilian casualties. These submarine bombardments added another layer of unpredictability to Japan’s already dire situation.

Conclusion: The Impact on Civilians

The Allied naval bombardments had a profound impact on both industrial production and civilian life in Japan. While the attacks disrupted industrial facilities, they also caused significant damage to urban areas and essential services. The Kamaishi’s ironworks attack alone destroyed 1460 houses and killed 424 civilians, while the total casualties from naval bombardments reached up to 3,282.

The Allied attacks were not just about destroying military targets; they were also a psychological weapon. The unpredictability of these naval shells, unlike the more predictable air raids, made them even more terrifying for Japanese civilians. As one might ask: How did these bombardments shape the perception of war in Japan? And what lessons can we draw from their effectiveness and the collateral damage they caused?
