Japan is Considering Building an ASAT Weapon

The government is considering launching a satellite to intercept foreign countries’ military satellites in the event of an emergency, as part of efforts to strengthen deterrence amid a rapidly increasing military threat in outer space, as seen in the development by China and Russia of satellites that can attack others, according to several government sources.

The government plans to make a formal decision on the introduction of such an intercepting satellite by the end of the next fiscal year so it can be launched in the mid-2020s, the sources said.
