Japan has established a Joint Operations Command (JJOC) that will oversee three branches of its Self-Defense Forces (SDF), a move aimed at improving coordination among its ground, maritime, and air units.
The JJOC brings the SDF in line with the U.S. and China, which have long operated under similar unified command structures. Officials said the new command will allow for faster decision-making and more flexible defense strategies, crucial for responding to growing regional security threats.
Japan’s government has framed the JJOC as part of its broader effort to counter escalating tensions in the Indo-Pacific, particularly China’s expanding military presence, North Korea’s missile threats, disputes over the Senkaku Islands, and potential conflict near Taiwan.
“Our country is now facing the most severe and complex postwar security environment due to geopolitical changes, and the expectations of the Defense Ministry and the Self-Defense Forces are becoming even greater,” Defense Minister Gen Nakatani said during a ceremony marking the command’s establishment. “Amid this environment, the establishment of the Joint Operations Command has great significance for the security of Japan.”
Chief Cabinet Secretary Yoshimasa Hayashi highlighted the significance of the new command, stating: “With the establishment of the Joint Operations Command, the SDF will be able to command its units centrally on a day-to-day basis, enabling it to maintain a flexible defense posture in response to developing events.”
The new command, based at the Ministry of Defense in Tokyo, will be staffed by approximately 240 personnel. General Kenichiro Nagumo, formerly vice chief of staff for the SDF’s Joint Staff Office, will lead the JJOC, overseeing major operational units and coordinating cross-domain missions, including cyber and space defense.
Speaking at a news conference, Nagumo underscored the urgency of modern defense preparedness. “It’s been about three years since Russia invaded Ukraine. I think it’s impossible to say a similar situation won’t happen in the Indo-Pacific,” he said.
Nagumo is expected to work closely with U.S. Forces Japan (USFJ) to enhance bilateral military coordination. The U.S. had previously announced plans to expand USFJ’s role to strengthen joint operations, aligning with Japan’s broader defense reforms.
The JJOC is also expected to oversee Japan’s newly developed counterstrike capability including the deployment of advanced weapons designed for such operations.
