I've wondered about this a long time. What are the general rules about J walking in Japan? Does such a law or rule even exist? There is a cross walk across a long street out in front of my dorms. The light is absolutely horribly designed and often brings traffic to a halt randomly, while never turning green if there is no cars. Many people, including myself, just don't even press the button and cross the street. Checking for cars of course. There is a police box nearby... and while I've never seen anyone get caught or in trouble for J walking, I'm very curious as to the rules here. Although most of all I want to take a hammer to this stupid crosswalk light...!
