Buses and taxis
The annual average of passengers in 1999 for buses has around 5.2 billion and for taxis, about 2.47 billion (the annual average for the JR railway trains has 8.7 billion). In 2001, there were about 256,000 taxis, both corporate and individually owned, in Japan. Fares vary, but in Tokyo the first two kilometers usually costs a little less than 700 yen. Bus fares also vary by region and route. Generally, the minimum fare is 150 yen, with the rate going up according to the distance traveled. In Tokyo, most buses charge a flat 200-yen fare regardless of distance.
