Summary
The April 2026 revision of Japan’s Road Traffic Act introduces stricter rules for cars overtaking bicycles. Drivers must maintain a minimum 1-meter gap or reduce speed to 20–30 km/h to ensure safety. Violations of these rules can lead to fines or even imprisonment. Bicycles are legally classified as vehicles and must ride on the left side of the road, increasing the frequency of overtaking situations. While cyclists welcome the new rules for safer passage, some drivers express concern about slower traffic and potential rear-end pressure. Given many roads are narrow, drivers must exercise heightened caution when overtaking bicycles to avoid penalties and ensure safety for all road users.
