NK's rocketry program advancing at rapid rate. Look what where NK is, if they have to do flight tests, they're not going to fly over PRC, RU or SKR due to geopolitics. Sometimes they're sensible and do lofted trajectories into sea of Japan, but every once in a while they need to overfly some land for proper tests, and JP is what's left. Historic grievances a bonus. Extra bonus JP can't test/overfly back without landing in countries above. Geography of missile tests gets interesting, India has to do it over ocean where foreign sigint ships can gather data, US/RU/PRC all have large empty regions to test inland away from prying eyes.
