Japan is planning to develop its own military space program, with a focus on reconnaissance, surveillance, and communications capabilities. The program, which will cost an estimated $10 billion, will be developed over the next decade, and will involve the development of new satellites and ground systems.

Japan has long been interested in space exploration, and has built satellites for both civilian and research purposes. However, the decision to develop a military space program is a significant departure from the country's previous policy of non-militarization of space.

The Japanese government says that the new space program is necessary to defend the country against potential threats, such as cyber attacks or space warfare. However, some critics have argued that the program could also escalate tensions with other countries, particularly China and Russia.

The development of Japan's military space program is still in its early stages, and it is not yet clear how far the program will ultimately go. However, it is clear that Japan is taking a significant step in its military capabilities, and the program could have a major impact on the future of space warfare.
