Japan started collecting a departure tax 1,000 yen (about 9 U.S. dollars) on Monday. Everyone will have to pay the International Tourist Tax, regardless of nationality, and it will be included in the price of a flight or boat ticket. However, children under two years old and those transiting within 24 hours are exempt. The number of tourists visiting Japan has risen significantly in recent years. This is partly because of relaxed visa regulations and a weaker yen, meaning tourists have more purchasing power than they did in the past.
