Japan's Anti-Missile Defenses -- Where They Are

To intercept an off course DPRK rocket-that-is-actually-a-long-range-ballistic-missile™ (roketto jijitsujo no chokyori dando misairu) or the an off-course jettisoned first stage of said rocket-that-is-actually-a-long-range-ballistic-missile™:

Patriot PAC-3 Missile Batteries

Protecting the Capital Area = 3

1) Ichigaya, Tokyo Metropolitan District
Grounds of the Ministry of Defense

2) Asaka City, Saitama Prefecture
GSDF Camp Asaka

3 Narashino City, Chiba Prefecture
GSDF Camp Narashino

Protecting the Nansei Islands and Okinawa = 4

1 and 2) Okinawa, Okinawa Prefecture

3) Miyakojima, Okinawa Prefecture

4) Ishigakijima, Okinawa Prefecture


Aegis Destroyers Equipped with SM-3 Missiles

Sea of Japan = 1

1) MSDF Myoko (DDG 175)
Left Maizuru Port on December 6, 2012

East China Sea = 2

2) MSDF Kongo (DDG 173)
Left Sasebo Port on December 6, 2012

3) MSDF Chokai (DDG 176)
Left Sasebo Port on December 6, 2012

Deploying three SM-3 equipped Aegis destroyers is a wee bit of overkill. For a comparative, three SM-3 equipped Aegis destroyers would be sufficient to protect all of Europe. But a) you can never be too sure and b) it is election season.


Later - The above will, of course, be supplemented by U.S. Navy anti-missile missile-bearing ships (Link).

Suffice it to say that Japan and South Korea will be over-protected from a rocket (or pieces of thereof) attempting to lift a satellite or a dummy payload weighing as much as a nuclear device.
