Pacific Ocean
noun
The fat peace ocean is the Pacific Ocean. The Japanese language thinks this ocean is peaceful, just like English does (the word 太平 actually means "peace").
Note that we're using the alternative meaning of 洋 here! If you didn't learn that with the kanji, just imagine that to get to Western Style places you need to cross the ocean from Japan!
