Roads in Japan use a left-hand traffic system. Since right-turning cars may
be waiting in the right hand lane of a two-lane road, keep driving in the left
lane if you do not intend to turn right. Don’t forget to use your indicators when changing lanes so that cars behind know your intentions.
(2) Right turning vehicles must wait
Drivers are asked to give way to oncoming vehicles in principle when the
driver intends to turn right. Make right turns after oncoming cars have
traveled past or turned left. Priority is given to left turns in Japan. There are no rules regarding giving way to right-turning cars.
(3) Never fail to stop when a traffic light is red.
(4) Obey arrow traffic lights.
When the traffic light is red, all cars must in principle stop. However, where
there are arrow traffic lights provided below or at the side of the traffic
lights, you may turn in the direction the arrow points when it is green.
Right-turn arrow traffic lights are the most prevalent.
When a right-turning arrow is shown, turn quickly
while paying full attention to oncoming vehicles.
Many intersections where this type of traffic light is
provided have right-turn-only lanes.
(5) Always pay attention to speed limits.
Speed limits are set at 30-50km/h in urban areas and 40-60km/h in the suburbs and on major roads. The speed limit is normally set at 70-100km/h on expressways.
(6) Pay attention to the no-overtaking zones.
(7) Bring your motorcycle to a complete stop at stop signs and in front of train crossings.
(8) Watch the traffic light in front carefully and do not start to move before the traffic light turns green. Traffic lights in Japan are located on the front side of intersections and you must stop your motorcycle rather far.
(9) Never drink and drive.
All over the world it is now considered common sense not to drive a car under the influence of alcohol. It is the same in Japan, however enforcement of the law and penalties for breaking it are stricter here. If alcohol is detected by a breath test, you will be penalized with imprisonment of up to three years or a fine of up to a 500,000 yen. Even more severe penalties are imposed for driving while intoxicated. In Japan, drivers who refuse to take a breath test are also punished. Sober passengers who ride together with a drunken driver as well as those who encouraged a driver to drink will also be punished. Never drink and drive.
You must stop before the stop line (or before the intersection when there is no stop line) at an intersection with a Stop sign,and yield to vehicles traveling on the crossing road.
