Japanese authorities are warning cyclists that using an umbrella while riding can lead to a 5,000 yen [1] traffic fine.

This enforcement coincides with the start of the rainy season in June [4], a period when visibility is reduced and the risk of road accidents increases. Because umbrellas obstruct a rider's view, the act is classified as a dangerous behavior that threatens the safety of other road users.

The penalties are part of a "blue ticket" system for bicycle violations. While reports on the exact start date vary, some sources said the system began in April 2024 [3], while others suggest a later implementation in April 2026 [3].

Under this system, those who do not comply with police warnings or guidance may be issued a ticket. The fine of 5,000 yen [1] applies to riders aged 16 and older [2], although some reports indicate that junior high school students may also be subject to these penalties [2].

Safety advocates emphasize that the danger extends beyond the rider. One report said the act of holding an umbrella while cycling on rainy days is a dangerous behavior that can lead to serious accidents. The restricted field of vision makes it difficult for cyclists to spot pedestrians or vehicles in time to react.

Police have increased vigilance across the country to curb these violations. The goal is to shift public behavior toward safer alternatives, such as using rain gear or helmets with visors, to ensure that the rainy season does not see a spike in preventable collisions.

“Guidance or warnings not followed may result in a 5,000 yen fine.”

The transition toward a stricter 'blue ticket' system for cyclists reflects Japan's effort to treat bicycle safety with the same legal rigor as motorized vehicle traffic. By introducing financial penalties for common habits like umbrella use, the government aims to reduce the high rate of urban bicycle accidents during seasonal weather shifts.
