The story

Movement (辶) that binds (束) distance: covering ground so quickly that space seems to compress. Japan's obsession with speed produced the 新幹線 (shinkansen), which travels at 速度 (sokudo) of 320 km/h. Yet Japanese speed isn't reckless: it's precise. Trains depart within seconds of schedule.

Used in 速度 (sokudo, speed), 高速 (kousoku, high-speed), and 速い (hayai, fast)
