After the North Korean missile-flyover of the northernmost island in the Japanese island chain – Hokkaido, more focus has been turned to missile defense. Many citizens are wondering how much time they would have between the launching of such a weapon by an enemy threat (say, North Korea) and their notification. The answer – mere minutes. While there are a number of anti-missile defense systems like the Aegis, they are expensive to install and potentially unconstitutional. Japan sits in a highly volatile portion of the Atlantic, with American bases stationed around the island as well, it is a large target for the North Korean regime should it decided to launch a first strike. With many civilians only hearing about the missile-passover after the weapon had already flown over Japan, it is pertinent that the Japanese Self Defense Force (JSDF) have the proper tools to counteract this threat.
