(CNA Reporter Dai Ya-chen, Tokyo, 22nd) A shell explosion accident occurred yesterday while the Japan Ground Self-Defense Force (JGSDF) was conducting tank live-fire training at the Hijudai firing range in Oita Prefecture, resulting in four casualties—three dead and one injured. Initial assessments suggest the cause was an artillery shell rupturing inside the turret, triggering a massive explosion in the confined space. This abnormal explosion inside a main battle tank has drawn intense scrutiny from the Ministry of Defense.
According to reports from Jiji Press and NHK, at the time of the accident, members of the Western Army Tank Unit were executing live-fire training with 120mm shells aimed at heavily armored tanks. The JGSDF explained that the explosion occurred inside the "turret" atop the tank. The three deceased were all inside it, while a female troop serving as the "driver," situated further away, became the sole survivor.
The 120mm shells used by the Type 10 tank involved in the accident are autoloaded, ordinarily stored in the turret and mechanically loaded into the firing position. A JGSDF source noted that, theoretically, once a shell is loaded into the chamber, the interior is equipped with safety mechanisms to isolate the blast from firing. However, this accident still resulted in severe casualties.
The Type 10 tank is Japan's domestically produced high-tech main battle tank, mass-produced since fiscal 2010. It boasts lightweight features and high digitalization, capable of networked joint operations with infantry and aerial reconnaissance units. Because it is a source of pride for the JGSDF, this accident has caused profound shock within the Ministry of Defense and the Self-Defense Forces.
The highest-ranking official of the JGSDF, Chief of Staff Masayoshi Arai, stated at an ad-hoc press conference yesterday, "Within my experience, I have no recollection of an ammunition rupture occurring inside a turret. We will ascertain the cause as quickly as possible," admitting that this accident is extremely rare.
Moreover, during the training, all members were equipped with radio communication, staying in touch with troops in other tanks. The JGSDF has begun questioning other troops who communicated with the involved tank to clarify the situation inside the turret and the dialogue at the time of the accident.
The JGSDF stated that in the future, while confirming the operational conditions and safety procedures at the time, they will collaborate with the manufacturers of the Type 10 tank and the ammunition if necessary to further investigate the cause and devise preventative measures.
In recent years, the JGSDF has seen a series of major accidents. In 2023, a multi-purpose helicopter crashed near Miyako Island in Okinawa Prefecture, killing 10 people. In 2024, an accident occurred during hand grenade throwing training at the Kita Fuji firing range, where a fragment struck and killed a member. This tank explosion accident once again raises public concern over the safety of SDF training. (Editor: Wei Shu) 1150422
