Though it's been a long time in coming, Japan announced its roll out of it's own Space Force. It seems likely it'll work side by side with the American Space Force in countering the perfidious post-Red Menace of China and Russia amd possibly deal with things like those aliens who backstab us in every Godzilla movie.
This will undoubtedly result in a glorious future where America and Japan can rule the Universe as Master and Puppet.
But yes, just FYI this was at least five years in the making.
