Trivia: The yen is the official currency of which country?
Libya
Australia
Thailand
Japan
The correct answer is Japan
So why is this answer correct? : The yen was adopted by the Meiji government on May 10, 1871. It replaced a complex monetary system that had been used since the Muromachi period in 1336. When introduced, people noted that the first national yen banknotes resembled U.S. banknotes. This was because they were actually printed by a U.S. company. Today, the yen (JPY) is the third-most traded currency in the world.
