japanese sentences are written as a mix of kanji, hiragana and katakana, you don't write japanese sentences in just kanji.
you won't see Singapore written as 新嘉坡 in Japanese except maybe on some official documents where it is some official name, just like you can see america referred to 米国 in similar instances. シンガポール is the way it is referred to and the kanji version is as good as extinct if you like, it is just not used when normally referering to your country. in the same way 豪州 is not used to refer to Australia, rather オーストラリア is used. Nagoyankee was pointing out with that reply to my post that you just won't see the kanji version in Japanese.
