Road circumstances in Japan
In Japan, cars runs on the left hand side of the road, and have steering wheels on the right. For those who are planning to drive with an international license, please note this point first.
In addition, in recent years, the number of people walking around the city borrowing a rental cycle is increasing, but as for bicycles, confirmation of traffic rules tends to be neglected. Unfortunately, we live in Japan as well, and recently troubles with bicycles are increasing.
The thing you need to remember is that bicycles are classified as "light vehicles" in Japan, and they need to run along the roadway with cars and are on the left side. Also, if you drive a bicycle after drinking you can be arrested for drunk driving. Although we have explained according to the traffic law so far, in the present situation, many bicycles run on the sidewalk. On a large arterial road, the roadway and sidewalk are separated by plantings, etc., and the distinction is clear, such as having a difference in elevation, but if you ask which way bicycles run on these roads, a high-performance long-distance bicycle is ridden on the roadway according to the traffic regulations, children riding shopping bicycles or bicycles tend to run on the sidewalk. There are not many things to pay special attention to in this regard, so you can say this is a vague point of Japanese traffic rules.
Roadways include general roads and highways, and highways are charged. General roads have signs of blue letters and highways have green signs, so they should be easy to distinguish.
Finally, a word about traffic lights. The Japanese are famous as citizens who obey traffic signals. Even if there are no cars at all, we teach children to absolutely obey their signals, so the vast majority of people obey traffic lights under all circumstanced. It seems that some people feel odd about this situation. Also, it is sometimes interesting that people call the signal color, which looks green, blue, meaning GO!
