Even North Korea can build their own Tomahaqks yet J*pan cannot lol.North Korean military is far superior in both capabilities and strength than japan.
Japan is an island. What are they going to shoot land attack missiles at?On the other hand they have plenty of anti-ship missiles, since as you heard: island.I'm optimistic those could easily be repurposed to hit land targets should it become necessary, like Atlantis suddenly surfacing next to them.
