This article refers to the Space security legislation in Japan and Poland. Both states have already prepared some legislation on Security in Space- the question is the following- if there is still a need of progress and if those presented legislation are sufficient for the practical purposes of the peaceful uses of Outer Space. Japan is a much more experienced state in using space than Poland; the same seems with the legislation. Poland as less experienced state in this matter has lots of ambitions to create the efficient legislation on Space security, so it must follow the good examples of states and institution in this matter. One of them is Japan. On the other state, Poland as a Member of EU must implement the European law in space security (in particular SSA), which seems to be priceless and efficient for the international cooperation in Space.
