Tokyo is pretty darn dense and the normal, legal speed of traffic in most areas with crowded crosswalks exceeds speed bump speeds. City and traffic planners are sure to be concerned with increased congestion and reduced road throughput by adding speed bumps to intersections that are already in the most congested spots.. I disagree that making it less safe to navigate intersections at currently observed speeds is a good way forward. I also believe that if speed reduction is a identified goal there are ways to accomplish this without making navigation at current speeds more dangerous; such as psychological speed bumps.
