City buses

All cities offer a city bus service. One has to evaluate city by city the most convenient means of getting around. For example, in Kyoto, city buses are essential, while the metro is almost ‘useless’.
On the contrary, in Tokyo, the metro is much more convenient than buses, which you can easily do without.
Small towns, on the other hand, such as Nikko or Nara, have no metro and so the city bus service is the only way to get around.
Buses have two doors, one in front and one about halfway down. You only enter through one (in Kyoto from the back) and get off at the other.
For city buses, there is no timed ticket as here in Italy, but you pay each time for the individual route. You get on and if there is a single fare (for example in Kyoto) you pay what you owe before getting off by inserting coins in a special machine. If, on the other hand, the fare is proportional to the distance travelled, you will have to pick up a ticket when you get on, which you will need to know how much to pay when you get off. In fact, there is an illuminated board above the driver with all the prices of the various stops indicated. As with the metro, there is the possibility of buying a season ticket.
