The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula and Russia. The Japanese archipelago separates the sea from the Pacific Ocean. It is bordered by North Korea and South Korea.
During the White House Siege, Kang Yeonsak ordered Speaker of the House Allan Trumbull to withdraw the U.S Seventh Fleet from the Sea of Japan along with all 28,500 U.S troops from the Korean Peninsula to allow a North Korean invasion of South Korea. The fleet was given the order to leave the Sea of Japan later on.
