to the north of Taiwan是某地在台灣的北方，而且某地不屬於台灣，如日本、韓國。in the north of Taiwan是某地在台灣的北部，某地就是台灣的一部分，如基隆、宜蘭。

To the north of X and north of X means that it lies beyond X on its northern side (or "above" X on a map oriented with North up). Some would infer that something which is "to the north of X" is not very distant from or relatively close to X, whereas a place "north of X" could be quite far from X.In the north of X means that it lies in the northern part of X.所以答案是 Japan is to the north of Taiwan. = Japan is north of Taiwan...
