“We express our deepest condolences to the family and loved ones of our Marine,” the division said.

An investigation has been launched to determine the circumstances surrounding the service member’s death.

The incident took place at Marine Corps Camp Schwab in northern Okinawa, a key US military installation in a region that accommodates a significant portion of the approximately 50,000 American troops stationed in Japan under the US-Japan mutual defence treaty.

Military authorities have not yet released the identity of the deceased, stating that the name will be made public only after the next of kin have been notified, in accordance with Pentagon protocols.

The 3rd Marine Division maintains several major units across Okinawa, including the 12th Marine Littoral Regiment, 4th Marine Regiment, 3rd Reconnaissance Battalion and Headquarters Battalion.
