WWII-Era Bomb Explodes, Causing Significant Disruption

A World War II-era US bomb exploded near the runway at Miyazaki Airport in southwest Japan on October 2. The explosion occurred in an area known for its history as a WWII Japanese Navy training field. The bomb, weighing 500 pounds, detonated unexpectedly, causing a 23-foot-wide and 3-foot-deep crater on the taxiway. Fortunately, no injuries were recorded despite the explosion’s severity, as it took place away from aircraft and airport personnel.

The explosion led to the immediate shutdown of the runway, resulting in the cancellation of 87 flights operated by Japan Airlines (JAL), All Nippon Airways (ANA), and other regional carriers. The affected flights typically connect Miyazaki with major Japanese cities such as Tokyo, Osaka, and Fukuoka. This disruption highlights the ongoing challenges posed by unexploded wartime explosives in historically affected areas.

 

Background of Miyazaki Airport and Unexploded Ordnance

Miyazaki Airport was originally a flight training field for the Imperial Japanese Navy and a base for kamikaze pilots during WWII. Over the years, the area has transitioned to civilian use, featuring a 2,500-meter runway and a single terminal handling both domestic and international flights. However, the remnants of its wartime past continue to pose significant risks. In 2023 alone, the Self-Defense Forces disposed of 2,348 bombs weighing 37.5 tons.

A bomb disposal team confirmed that the explosion was caused by an American bomb from a wartime air raid. The incident is under investigation to establish the exact cause and to ensure enhanced operational safety at the airport. The team expects repairs to fill the crater to be completed by Thursday morning, allowing the airport to resume normal operations swiftly.

Continuing Threat of Unexploded Bombs in Japan

Unexploded bombs remain a persistent threat in Japan, especially in areas that were heavily targeted during WWII. Miyazaki Airport has had multiple bombs discovered in the past, making frequent inspections and bomb disposals crucial. Major airlines, including Japan Airlines, All Nippon Airways, and Solaseed Air, operate from Miyazaki, connecting key destinations and international routes to Taiwan and South Korea. Despite the risks, the airport has continued to function as a vital hub in Japan’s aviation network.

The unexpected detonation at Miyazaki Airport serves as a stark reminder of the lingering effects of past conflicts and the continuous effort needed to ensure safety in historically affected areas. As the airport prepares to reopen, authorities are keen to implement even stricter safety measures to prevent such incidents in the future.
