On November 22, 1978, over 3000 bosozoku motorcycles and cars swarmed the streets of Tokyo, cruising, parading, revving and generally causing a ruckus. On the following day a new Japanese traffic law would require helmets for all motorcyclists. So a huge shukai (meet) was held the night before and from that day forth the 22nd of November of each year became a bosozoku Memorial Day of sorts. The Japanese call it doukoho, short for douro koutsu hou kaisei, or Road Traffic Law Change. So strap on yourtsurikawa, pommade up your regento, crank up some Kishidan and tear up the night!
