On our recommendation on making your own designed trip driving in Japan, we strongly wish that you would follow the road rules in Japan and you to have a safe journey. The first step of safe-driving would be for you to follow the road signs correctly. Some are the same but some are different as those in your countries. Some will be difficult because they are written in Japanese. It will surely be your help if you put these signs in your mind beforehand. Trust us! It won’t be that difficult to memorize them.
