02Overview
What Suzuka is like to drive.
The 鈴鹿サーキット layout at Suzuka is 3.61 miles with 19 corners worth setting up for. A generic track-day car in our model brakes hard 14 times a lap and is at full throttle for about 43% of the distance; the longest straight runs roughly 2379 ft.
6 of the corners are slow (under 50 mph in the model), 5 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Suzuka later.

The speed trace is a model, not a real lap: a generic track-day car (about 1.1 g of cornering grip, 1 g braking, 150 W/kg) driven on the computed line through an assumed 12 m wide track. Use it to see where the braking zones and flat-out sections are, not to predict your speeds. Elevation data for this track isn’t loaded yet.
04Corner by corner
The corners at Suzuka.
TRACK’s own corner numbering (C1, C2…), found from the curvature of the mapped centerline. It isn’t the official turn numbering. Each diagram shows the computed line: the minimum-curvature path through an assumed 12 m wide track. It’s a geometric starting point. Your instructor’s line comes first.

↱ RightmediumhairpinTRACK numbering
A medium right-hand hairpin that turns about 187°, tightening to a radius of roughly 40 m (131 ft). The model car brakes for about 20 m (66 ft), from 60 to 59 mph. The computed line turns in from the left side, takes a late apex, about 40 m after the corner’s geometric apex, and lets the car run out to the left on exit.

Every mapped loop at Suzuka.
TRACK finds each closed loop in the OpenStreetMap raceway network. Named layouts come from OSM circuit relations; the rest are named by length, and some may be combinations the venue never runs. Your first session confirms which one you drove.

06Time it with TRACK
Drive Suzuka. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Suzuka and the layout from your GPS trace, then times every lap and sector with a live delta to your best.
- 1DetectTRACK matches your first few hundred metres against every mapped layout at Suzuka, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is estimated. When you’re stopped, TRACK shows it on the map: accept it or tap to move it. You’re never asked while driving.
- 3Laps, timed retroactivelyLaps you drove before confirming are timed from the recorded trace, so you don’t lose your first session.
- 4Go furtherSync a GoPro for video with telemetry and let TRACK Engineer point out where the time is. External 10–25 Hz GPS receivers for tighter sectors are awaiting hardware validation.
- Venue and layout detection is tested on simulated drives over real OpenStreetMap circuits, not yet in a real car. Compatible GPS receivers

FAQ
Suzuka, answered.
How long is Suzuka?
OpenStreetMap maps 3 closed loops at Suzuka Circuit, from 1.39 mi to 3.61 mi (5.81 km). These are mapped centerline lengths; the venue’s published figures can differ slightly. The published length we cross-check against is 3.61 mi.
Which direction does Suzuka run?
The main mapped layout runs clockwise, from one-way tagging in OpenStreetMap. Check the event’s driver briefing: some venues run reverse-direction days.
Can I time laps at Suzuka with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Suzuka and the layout you’re driving from GPS, then times laps and sectors. A phone’s GPS is good for lap times; an external 10–25 Hz receiver tightens sector splits.
Where is the start/finish line at Suzuka?
TRACK estimates the line from the mapped geometry (usually beside the pit lane, or on the longest straight). It isn’t verified on site, so the app asks you to confirm or move it before timing your first session here.
How do I find track days at Suzuka?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar (also linked) lists its events too. TRACK doesn’t list events itself.
Where can I stay near Suzuka?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Suzuka from OpenStreetMap, with straight-line distances. Book early for big event weekends.
