We have launched an invasion of Vladivostok from across the Sea of Japan, pirates cannot get in that sea due to the immense storms that they are realistically not going to be able to take with their lack of experience and ill equipped navy, meanwhile the Japanese who have lived around that sea ever since they existed as a nation, will be able to take it with our fleet. So, we invade the city of Vladivostok Itself and the coast a little bit north with a supply line running along our naval invasion route. This will not be an easy invasion as they at least have a city to recruit from, also they would be more likely to have enough money to field an army, so we're digging it on the shore to prepare for a further invasion. Meanwhile our invasion of Sakhalin is planned to be a breeze as they are an island with no major cities and very close to our coastline. So we'll just land some Marine Divisions there and take the island without too much of a headache. Also, the islands north of us, the small ones are also being seized, they are close enough to be invaded easily, and they are so small they shouldn't have a strong defense force.
