Taxis are an expensive way of getting around cities in Japan, though nascent deregulation moves are easing the market a little. In many cities, for instance, the first 2 km (1 mile) costs ¥730 and it's ¥90 for every additional 280 meters (400 yards). Between 10 pm and 5 am there is a 20% service charge. If possible, avoid using taxis during rush hours (7:30–9:30 am and 5–7 pm).
In general, it's easy to hail a cab—simply raise your hand. Japanese taxis have automatic door-opening systems, so do not try to open the taxi door. Stand back when the cab comes to a stop—if you are too close, the door may slam into you. Only the curbside rear door opens. A red light on the dashboard (visible through the front window) indicates an available taxi, and a green light indicates an occupied taxi.
Drivers are for the most part courteous, though not necessarily chatty. Unless you're going to a well-known destination such as a major hotel, it's advisable to have a Japanese person write out your destination in Japanese. Your hotel concierge will do this for you. Remember, there is no need to tip.
