シンガポールには首相と大統領がいます。首相は執政の最高責任者、大統領は国の代表です。Istanaは大統領官邸。11月の一般公開の際に訪れてみました。内部は撮影禁止でした。

Singapore has prime minister and president. Prime minister is a head of government, while president is a representative of the nation. Istana is the house of the president. We visited there when it was opened to public in November. Photo of inside the house was not allowed.
