OvertakingJapan
26. Overtaking
Overtaking is the act of passing another road user travelling in the same direction. It normally involves moving to another position or lane, passing the slower road user and returning to the appropriate position when it is safe.
Before overtaking, a driver should make sure there is sufficient visibility and space, check mirrors and blind spots, signal when required and ensure that no other road user is already overtaking. The manoeuvre must be completed without exceeding the speed limit or endangering other road users.

On which side do drivers normally overtake in Japan?
As traffic normally keeps left, drivers ordinarily overtake on the right. This is the general rule, not permission to pass wherever a lane is available; exceptions and restrictions depend on the local law.

When should you avoid overtaking in Japan?
Do not begin if approaching traffic, restricted visibility, road markings, an intersection, a crossing or another road user makes the manoeuvre unsafe or unlawful. Check behind and ahead, allow enough space and never exceed the speed limit to complete the pass.

What extra care is needed when overtaking slower road users in Japan?
When overtaking, comply with Article 28 and allow safe clearance for the speed and circumstances. Separately, from 1 April 2026, Article 18(3) requires a safe speed appropriate to the available gap when a motor vehicle passes to the right of a same-direction bicycle or specified small motorised bicycle, outside an overtaking manoeuvre, without sufficient clearance. Do not treat guidance distances as a fixed statutory minimum for every pass. Wait if you cannot pass safely; Article 18(2) separately protects pedestrians through safe clearance or slow travel.
