No, the Japanese Shinkansen (bullet train) is the opposite of violent; it is famously one of the smoothest transportation experiences in the world. Even while traveling at speeds of up to 320 km/h (200 mph), the ride is so stable that you can stand a coin on its edge on the window sill without it falling. The "violence" associated with high speed is negated by advanced active suspension systems and "long-nose" aerodynamic designs that prevent the "tunnel boom" effect. While you might feel a slight "pressure pop" in your ears when entering a tunnel or a gentle tilt when the train "banks" into a curve, there is no vibration, shaking, or lurching. It feels more like floating on air than riding on rails. This extreme level of comfort is why many travelers prefer the train over flying, even for long distances across Japan.
