Just as Japan was trying to handle the military threat from Russia's Navy, its neighbor, South Korea, suddenly exerted force. South Korean Naval Warships were dispatched to patrol the waters west of Japan with the aim of clearing the nearby seas of pirates.
South Korea and Japan are historical enemies, with South Korea suffering from Japanese oppression without the power to retaliate. Now, having noticed the annihilation of the Japanese Navy, they seized the opportunity to loot a burning house, threatening Japan's security with warships for the first time in hundreds of years. As for the pretext of clearing pirates, it was a sheer mockery of Japan.
