The Japanese MSDF could easily take on & launch a blockade of North Korea on their own.But Im not so sure about the offensive capabilities of JASDF.I read that a study undertaken by the Japanese government showed that Japanese warplanes had a limited stock of precision guided munitions for use on strike missions(leaving them vulnerable to enemy fire as well) & they were also hampered by a limited number of aerial refuellers.
