Q. Which of the following countries calls itself Nippon?
Answer:
Japan
Notes: Japan calls itself "Nipon" because this was the original name for the country in the native Japanese language. The word "Nipon" is derived from the Chinese characters 日本, which literally mean "sun origin" or "origin of the sun." This name was chosen because Japan is located to the east of China, and the Chinese saw Japan as the land of the rising sun.
Over time, the pronunciation of the Chinese characters for Nipon changed in Japanese, and the word became "Nippon." This is the modern Japanese name for Japan, and it is used on Japanese currency, stamps, and official documents.
In English, the country is commonly referred to as "Japan," which is derived from the name "Japannes," which was used by Marco Polo and other European explorers who visited the country in the Middle Ages. The name "Japannes" was a corruption of the Chinese name "Cipangu," which was derived from the Chinese characters for Nipon. So, while Japan is known as Nippon in Japanese, its English name ultimately has the same origins.
