Getting that 100% road completion stat in Forza Horizon 6’s virtual Japan is proving to be a massive headache for the community. The game features a total of 671 roads. While driving through the neon-drenched streets of Tokyo or drifting down the winding hairpins of Mt. Haruna will naturally check off most of them, almost every player gets stuck at 668 or 670 roads.
The map looks fully colored, yet the tracker stubbornly sits at 99%. This is because Playground Games built a highly vertical, multi-layered map where "secret" or missing segments hide directly under overpasses, blend into dirt tracks, or lock behind late-game map expansions.
If you are tearing your hair out trying to find that one final sliver of asphalt, this guide will show you exactly how to uncover the most heavily obscured roads on the map and claim your full completion rights.
Before you spend hours squinting at your screen, check your progression. You cannot actually hit 671/671 roads purely on the mainland.
The final batch of roads is locked behind Legend Island, a late-game unlock. If you haven't unlocked this zone yet, you will cap out at 668 roads. If your stat tracker says 668/671, stop driving around Tokyo and focus on completing your festival stories and horizon campaign milestones to open up the island. Once Legend Island is unlocked, the final three roads will become accessible to complete your collection.
If you already have access to the full map and are still missing a few segments, the culprit is almost certainly one of these three notoriously bugged or layered locations:
The multi-lane highway system in southern Tokyo is a maze of stacked concrete. Players frequently assume that because they drove the top toll road, the entire segment is cleared. However, there are up to 6 lanes layered directly on top of each other in the Daikoku area.
The Culprit: A tiny lower-level lane turning left just past the second bridge from the Rainbow Bridge. Because it sits directly under an upper overpass, the grey "undiscovered" tint is visually masked by the rendering of the top road.
Dirt roads in rural biomes like the Ohtani and Ito regions use an orange dashed overlay on the map.
The Culprit: When you miss a micro-segment of a dirt road (often just 5 to 10 meters long), the missing portion only occupies the empty space between the orange dashes. Visually, the line looks fully connected and completed when you zoom out, making it completely invisible to the naked eye.
The Culprit: The literal last meter of the Tokyo drag strip and the tight service paths surrounding the traditional castle grounds. If you don't slam your car's bumper directly into the barrier at the very end of these tracks, the game registers the road as 99% explored and refuses to grant the discovery.
Since finding these slivers visually is almost impossible, the community has figured out a brilliant mechanical workaround called the "Fast Travel Scrubbing" method.
Open Map → Press RB / Filter Menu → Uncheck All Markers (Races, PR Stunts, Houses)
Once you have a completely clean view of just the roads, do not just look at them. Instead, use your mouse cursor (if on PC) or your controller thumbstick to rapidly trace along the roads section by section.
Watch the bottom info bar of your UI carefully. Because you can fast travel to any discovered road, the "Fast Travel" button prompt is constantly active as your cursor glides along the map. The exact second your cursor passes over an undiscovered pixel—even if the road looks completely colored in—the Fast Travel prompt will instantly blink out or disappear. When the prompt vanishes, mark that exact spot, drive your car over it in-game, and watch your discovery notification finally pop.
If you don't want to spend two hours scrubbing your map like a paint brush, you can leverage community-made EventLab blueprints designed specifically for road sweeping.
Experienced creators have mapped out optimized, automated routes that intentionally route through every single easily-missed sliver on the map. You can load these up by navigating to the Pause Menu → Creative Hub → EventLab → Search Blueprint, and entering these community share codes:
Tokyo Highway & Overpass Clean-up (Part 1): 114 192 942 (25–35 minutes)
Tokyo Highway & Overpass Clean-up (Part 2): 265 009 342 (10–20 minutes)
Center Map & Mountain Passes Sweep: 307 242 606 (20–30 minutes)
North Map & Rural Connectors: 752 483 668 (20–30 minutes)
To use these efficiently, hop into a heavy, stable vehicle like the Toyota Tacoma FE, turn on your steering assists, and let the auto-drive coast you through the missing zones while you sit back.
