Just a rumor, could be a guess, in some dark web posts, I saw.

So like, after Kaiba Corp withdrew as Japan's leading arms manufacturer, Leo Corp took over at least for the production of next generation ICBMs in the Japanese arms industry, and at least developed a few prototypes.

And, like I doubt this'll happen, because who's that stupid to do it.

There's rumors that one of those missiles moved recently... and there's the rumors that the Ultra Nationalists are pushing for bombing Faerie Tower.
