>>1 OP wrong place for this as it is clearly not news as it is just a toy which I have seen before, this should have been posted in the Technology board.
And I have my doubts that Japanese *government* will make an approval to use this kind of weapon "when we have the technology to make such a weapon in the future".
also you need a link to a reliable source of info stating what you are claiming is true, I,e maybe NHK world news website if it's on there.
