well if you plan to keep the stracture of the world as it is now (unlike some theories that exist) here are some ideas for names:

-The four sacred beasts : Turtle ,Dragon,Tiger,Phoenix.You could connect the naming of the seas with those beasts/deites that could even exist somewhere and guard their terittories.

-The four seasons: Winter,spring,summer,fall. Mainstream connection between the seas and the weather conditions.

-The four sacred obligations one must develop:a strong body, a clear mind, a pure spirit, and a devotion to the welfare of others.

-The four elements: fire,water,air,earth.This could also help you imagine certain island themes.

-The four races colors: Black,white,yellow,red.This could also be a hint to the looks and habits of the inhabitants.

-Precious metals: Gold,silver,copper,iron or any other you like.

-Random names without theme: "sea of Ion", "sea of Ikaros", "mediterranean sea", "Warrior's sea", "Peril's ocean" blah blah blah

Sorry for my rambling just thought i could help.
