Number of motorcycles in use in Japan 2006-2023

As of March 31, 2023, Japan recorded approximately 10.3 million motorcycles in use, down from roughly 11.69 million in 2014. The development over the past decade indicates a slow, yet consistent, decrease in motorcycles owned. The Japanese motorcycle landscape The Big Four — Honda, Suzuki, Yamaha, and Kawasaki — dominate the domestic motorcycle market, splitting the lion’s share of bike sales between them. Among Japanese motorcycle owners, there is a strong preference for lighter machines with a cylinder capacity of up to 125cc. On the other hand, most larger domestically produced bikes are export products for motorcycle dealers abroad. Road safety for motorcyclists in Japan The number of motorcycle accidents in Japan had recently increased for the second time, but was overall on a declining trend, corresponding to the downwards trend of road traffic accidents in the country. An amendment of the country’s Road Traffic Act, implemented in mid-2020, imposed more severe penalties for aggressive driving and road rage. Under the revised law, obstructive driving and malicious behavior on the road are now punishable, even in the absence of accidents.

截至2023年3月31日，日本注册在用的摩托车数量约为1030万辆，较2014年的约1169万辆有所下降。过去十年的发展趋势表明，摩托车保有量呈现出缓慢但持续的下降态势。在日本的摩托车市场格局中，四大品牌——本田、铃木、雅马哈和川崎——占据主导地位，它们之间分割了大部分的摩托车销售份额。在日本摩托车车主中，对轻便车型有着强烈的偏好，这类车型的气缸容量不超过125cc。另一方面，大多数国内生产的较大型摩托车是供海外摩托车经销商出口的产品。关于日本摩托车驾驶员的道路安全，日本的摩托车事故数量最近两次均有所增加，但总体上仍处于下降趋势，这与国家道路交通事故的下降趋势相一致。2020年中旬实施的《道路交通法》修正案对鲁莽驾驶和路怒行为实施了更严厉的处罚，根据修订后的法律，阻碍交通和道路上的恶意行为现在即使在未发生事故的情况下也将受到惩罚。
