What is the "Space Operations Group"? What is Japan's intention in reaching out to space?

Recently, the Japanese Senate held a plenary session and passed amendments to the "Ministry of Defense Establishment Act," officially renaming the "Air Self-Defense Force," which has been in use for 72 years, to the "Aerospace Self-Defense Force," clearly stating that "the space domain will be designated as a new area of operations." The "Aerospace Self-Defense Force" will be established within this year, and a new "Space Operations Group" will be created, specifically responsible for the space domain, commanded by the highest-ranking officer of the Air Self-Defense Force, to advance satellite launches and enhance monitoring capabilities of space situations. So, what is the "Space Operations Group"? How powerful is it? What kind of threat will it pose to neighboring countries? Read on to find out ↓

Timeline for the establishment of the "Space Operations Group"

In fact, the establishment of the "Space Operations Group" has long been in the making.

In 2020, the Japan Air Self-Defense Force established the "Space Operations Team," which initially had about 20 personnel.

In 2022, it was reorganized into the "Space Operations Group."

In March 2026, it will be further expanded into the "Space Operations Regiment," increasing its personnel to 670.

In the fiscal year 2026, after being upgraded to the "Space Operations Group," the personnel size will increase to approximately 880.

What is Japan's intention in reaching out to space?

This is the first time in 72 years that Japan's Air Self-Defense Force has changed its name, now becoming the "Aerospace Self-Defense Force," and it has also newly established a so-called "Space Operations Group." What is Japan's intention in extending its reach into space?

Military commentator Zhang Xuefeng: The Japanese Self-Defense Forces believe that space is an important operational domain that will play an increasingly significant role in future modern warfare. Space-based platforms can provide satellite navigation, communication, and reconnaissance surveillance. Japan's next step is to vigorously develop space-based systems to support the development of offensive capabilities.

What kind of threat will the "Space Operations Group" pose to neighboring countries?

Military commentator Zhang Xuefeng: Currently, the proclaimed "Space Operations Group" is mainly used for reconnaissance, surveillance, and early warning, but in reality, it can be seen that Japan has been developing some offensive space-based capabilities in recent years. For example, in 2025, Japan's Minister of Defense claimed that Japan had made substantial progress in the technology of interfering with other countries' satellites. This interference technology is a form of soft kill capability that can disrupt the communication satellites of adversaries and may even develop certain laser weapons to interfere with the adversary's space-based reconnaissance platforms.

Additionally, Japan is also developing some so-called spaceplanes and space carriers, claiming they will be used in the future to clear space debris, but in reality, the related technology can be fully utilized to strike adversaries' low Earth orbit satellites. Japan's defense capabilities will further improve, and after the establishment of the "Space Operations Group," it can provide intelligence support for anti-satellite capabilities.
