Riding on the Left Side of the Road

Short Answer

In Japan, bicycles normally ride on the left side of the roadway, moving with traffic rather than against it.

Official Rule / Basic Rule

Cyclists should generally ride on the left side of the road and follow traffic direction. Local signs and police instructions always take priority.

RideNippon Advice

Stay predictable, hold a steady line, and avoid drifting toward the center of the lane unless you need to avoid hazards. On narrow roads, communicate early with your position and lights.

Why It Matters

Riding against traffic surprises drivers and pedestrians. It also makes intersections, driveways, and side roads much more dangerous.

Common Mistake

Some visiting riders ride on the right because it feels normal in their home country. In Japan, that can look reckless and can put drivers in a difficult position.

When to Avoid

Avoid high-speed riding on narrow urban roads when traffic is heavy and you cannot hold a stable line.
